Re: iPhone Simulator auto-rotation touches detection bug?

void CallOBJC(void);
}
MyClass::CallOBJC()
{
[objcptr updateText];

Just like that. Put this into a .mm file, and it'll compile as Objective-C++.
You'll get a compiler warning that objcptr may not respond to updateText, which
you can eliminate by casting objcptr to the appropriate class.
I've done this very thing, but from plain ol' C.

Detect links in UITextView fails on email addresses?
I have 2 UITextViews in a view; one contains a web address, the other an email address. The former, when touched, launches Mobile Safari and loads the web page. The latter, the email address, when touched, does nothing, even though the view has colored it blue and underlined it. If I touch-and-hold, I do get the action sheet asking whether to make a New Message, Create a Contact, etc. Am I wrong in assuming that touching the e-mail address should actually launch Mail and create a new message to that address?

Image gets wrong resolution value on Snow Leopard
In this application, I have a method that reads in an image and writes it back
out with a different resolution. This resolution is specified by the user via
a textfield in a sheet.
On Leopard, the method works as expected; whatever value for the resolution is
specified is what is actually used to write out the image.
But on Snow Leopardsigh. The client has asked that this textfield's value
default to 250, indicating the image should be written out with a DPI of 250
pixels/inch. When that value is used, the resulting image does NOT have a
resolution of 250, but rather 72.05 x 72.03 pixels/inch as indicated by
Preview's Info window. GraphicConverter and Photoshop agree with this. I
tried various values, including 249, 248, 245, and 239--all these resulted in
the wrong value, but lo and behold 240 *works*.

Maybe you should make your implementation signature match the

The error in the Debug Build Configuration leads to an interruption
of the build process, hence I cannot debug my application, **this is
my main problem!!!**.
Actually, you're main problem is your code doesn’t match the
prototype; inability to build and/or debug is merely a symptom.
The warning in the Release Build Configuration however leads to a
properly built application. After running the application, the
expected behavior works well, no issues at all.
Sounds like a difference in compiler settings between the two
configurations. This, however, is not the problem though.
Using Xcode 3.1.3 (and Leopard 10.5.8), there is nor an error
neither a warning in both, Debug and Release mode. Everything works
fine.
The compiler used by Xcode 3.2 is stricter than previous
versions.___

Shark newbie needs help with perf-opt
I'm trying to optimize an iPhone app. I have dozens of objects (as many as 60 at a time) moving around the screen at once. Under certain conditions, these objects will collide, and during these collisions, the rest of the objects (the ones not involved in the collisions) slow down noticeably. I had assumed it was the collision detection code that was causing this problem; I still think so, but the results I'm seeing in Shark beg to differ. I have to believe that it's a matter of interpretation of the Shark data, and I'm hoping someone can set me straight. The objects are moved in as NSTimer callback; after all the objects are moved on screen, collision detection is done, via a nested loop involving all the already-collided objects against all the rest of the objects. When I run an instance of this behavior in Shark, it tells me that 16.9% of the time is spent in object movement, while only 5.0% of the time is spent detecting collisions. The reason I don't think this is correct is because the object movement degrades noticeably in direct proportion to the amount of collisions currently in progress. When the maximum number of objects are moving absent any collisions, the movement is fluid; only while collisions are occurring does the movement degrade (objects involved in collisions are currently only being drawn at a different size (via the frame property being adjusted). So I turned my attention to the movement code. The objects are UIViews, whose -drawRect currently consists of only setting a color and drawing a circle (and takes 8.5% of the CPU time). My original code for this consisted of explicit Core Animation, um, animations, which caused other problems with collision detection. So I changed the movement code to manually calculate where each object should be at a given time, and simply set its center property to move it. Of the 16.9% of the time spent in my move method, more than half of that time (9.3%) is spent in CALayer -setPosition:. I got rid of explicit CA animations, but I guess I'm stuck with implicit ones? Is is possible to disable these on iPhone? I don't really care to have *any* animation done during the move method, as I'm setting the absolute position of the objects where they need to be when they need to be there, so I think I want to get rid of the implicit CA stuff--am I right? I think the reason I'm seeing so much activity in the move method is because that's happening constantly during the run of the program, while the collision detection code happens only sporadically, but clumps enough to slow down the movement code. Reasonable? Am I off my rocker? Am I misinterpreting the Shark data? Any other optimization tips? I'm continuing to tinker with stuff, but while working on that I wanted to post this before I got too far down the road/into the weeds.

I create the object in the first place in order to pass it as the past argument to a document's - saveIn:as:copying:appending:withOptions: method. It doesn't really belong to a container object (AFAICT), so when the doc says Immediately after creating the object, insert it in the appropriate element array. The object is not “viable” in the application until it has been added to its container. Consequently, you cannot set or access its properties until it’s been added., I'm at a loss figuring out which container it is supposed to be added to before I can even do options.quality=12; in order to pass it to that method. I'd love to be able to query the document to get this (so that I can do this only if the quality is not already 12), but I've found no way via AppleScript to find this out. Currently, I'm using do shell script to run the command line tool 'exiftool' to query the image file for the PhotoshopQuality EXIF value, but I'd like to avoid this if possible.

Scripting Bridge link error
I am trying to use Scripting Bridge to do some minor control of Adobe
Photoshop CS3 from my Cocoa app. I have followed the instructions in
the Scripting Bridge Programming Guide for Cocoa, specifically:
1. Generate header files for all scriptable applications that your
code is sending messages to: I used sdef /Users/Shared/Adobe\
Photoshop\ CS3/Adobe\ Photoshop\ CS3.app | sdp -fh --basename
AdobePhotoshopCS3 to generate this header.
2. Add these files to your project. (done)
3. In your header or implementation files, add #import statements for
the generated header files. (done)
4. Add the Scripting Bridge framework to your project. (done)
Here is the modest amount of code I'm using right now:
AdobePhotoshopCS3Application *psApp = [SBApplication
applicationWithBundleIdentifier:@com.adobe.Photoshop];
if ([psApp isRunning]) {
SBElementArray *docs = [psApp documents];
NSUInteger index ;
AdobePhotoshopCS3Document *doc;
AdobePhotoshopCS3JPEGSaveOptions *options =
[AdobePhotoshopCS3JPEGSaveOptions new];
options.quality = 12;
for (index = 0; index [docs count]; index++) {
doc = [[docs objectAtIndex:index] get];
[doc saveIn:doc.filePath
as:AdobePhotoshopCS3SvFmJPEG
copying:NO
appending:AdobePhotoshopCS3E300NoExtension
withOptions:options];
}
[options release];
}
It compiles fine, but I get this link error:
Undefined symbols:
.objc_class_name_AdobePhotoshopCS3JPEGSaveOptions, referenced from:
literal-
poin...@__objc@__cls_r...@adobephotoshopcs3jpegsaveoptions in
AMBatchEditMonitor.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
It's in the header file that got generated
@interface AdobePhotoshopCS3JPEGSaveOptions :
AdobePhotoshopCS3SaveOptions
@property BOOL embedColorProfile; // embed color profile in document
@property AdobePhotoshopCS3E270 formatOptions; // ( default: standard )
@property AdobePhotoshopCS3E880 matte;
@property NSInteger quality; // quality of produced image ( 0 - 12;
default: 3 )
@property NSInteger scans; // number of scans. Only valid for
progressive type JPEG files ( 3 - 5 )
@end
but where's the object code for it? The other classes used
(AdobePhotoshopCS3Application and AdobePhotoshopCS3Document) are
apparently linked OK, so what gives with the JPEGSaveOptions?
Thanks!

So anyone has an idea for this?
In the -touchesBegan, set a timer for 2 seconds; in the timer
callback, do whatever it is you want to do (jiggle icons, for
example). However, if you get a -touchesEnded (or -touchesMoved, as
appropriate for your use case) *before* the timer fires, invalidate
the timer and carry on as if nothing happened.

You want to change the contentMode on the UIView if you want it to redraw (and understand that there is a performance penalty for doing this). That thought actually did occur to me, but I dismissed it for several reasons: 1) The event that causes the explosion is another ball being placed into the view by a click, and everything about this catalyst ball is exactly the same as all the other balls, except it never gets the initial movement animation applied to it. This catalyst ball correctly animates its diameter change animation. B) My interim fix was to remove the original ball view that was moving, create a new ball view with the same properties as the old one and insert it into the parent view, then apply the explosion animation--essentially the same thing as the catalyst ball above. Works great, no jaggies, perfect circle. Again, this object is the same type, created the same way, as all the others, it just doesn't have the initial animation applied to it. That was enough to convince me that there was something else going on, implicating the animation as being part of the problem. Regardless, I changed the contentMode of the animated balls to UIViewContentModeRedraw just to see what would happen, and now it doesn't expand at all. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Core Animation rendering problem
Probably not the best subject line, but best I could come up with...
I an animating a ball across the screen, using this code:
CABasicAnimation *animation = [CABasicAnimation
animationWithKeyPath:@position];
animation.duration = duration;
animation.delegate = self;
animation.timingFunction = [CAMediaTimingFunction
functionWithName:kCAMediaTimingFunctionLinear];
animation.fromValue = [NSValue valueWithCGPoint:self.center];
animation.toValue = [NSValue valueWithCGPoint:intersectPt];
self.layer.position = intersectPt;
[self.layer addAnimation:animation forKey:@position];
No problem. Works great. Now, something happens and I want to stop
the motion of the ball, and start a new animation that increases the
diameter of the ball. I do so by doing
[self.layer removeAllAnimations];
if (speed 0) {
self.speed = 0.0;
CGPoint here = ((CALayer *)(self.layer.presentationLayer)).position;
self.center = here;
}
to stop the ball in place (which seems to work, as the following
animation is done at the correct location) and then I start a new
animation that increases the size of the ball, like so:
[UIView beginAnimations:nil context:NULL]; {
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView
setAnimationDidStopSelector:@selector(explosion:finished:context:)];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
CGFloat delta = (kParticleSizeExplode - kParticleSizeNormal);
CGRect newBounds = self.bounds;
newBounds.origin.x -= delta/2.0;
newBounds.size.width += delta;
newBounds.origin.y -= delta/2.0;
newBounds.size.height += delta;
self.bounds = newBounds;
} [UIView commitAnimations];
The problem occurs while drawing the ball during this 2nd animation;
instead of redrawing the ball at increasing sizes, so it's nice and
round, instead it appears that the small ball is simply being scaled
up, and is very jaggy.
Here's my -drawRect: for the ball:
CGContextRef context = UIGraphicsGetCurrentContext();
const CGFloat *components = CGColorGetComponents(self.color);
CGContextSetRGBFillColor(context, components[0], components[1],
components[2], 1.0);
CGContextFillEllipseInRect(context, [self currentBounds]);
The -currentBounds method is a convenience method to get the current
bounds of the object, whether it is part of an animation currently or
not:
- (CGRect)currentBounds
{
CGRect bounds = CGRectZero;
CALayer *presLayer = self.layer.presentationLayer;
if (presLayer == nil) {
bounds = self.bounds;
}
else {
bounds = ((CALayer *)presLayer).bounds;
}
return bounds;
}
Any idea why the drawing is screwing up for the 2nd animation? Are
the 2 different methods of animating messing up each other somehow
(even though I've removed the 1st animation)?
Tips/suggestions/comments appreciated.

SecRandom.h on iPhone OS 2.2.1?
I started working on a new project, and started out using the 3.0 SDK; I'm now far enough along to realize that I don't really need to eliminate older versions, so I switched the Base SDK to 2.2.1. I do, however, use the Security framework, specifically SecRandomCopyBytes() to generate random numbers. For 3.0, this simply required adding Security.framework to my project and #importing Security/Security.h. However, when I switch to 2.2.1 and build the project, SecRandomCopyBytes and kSecRandomDefault are undeclared, even though they are documented as being Available in iPhone OS 2.0 and later. When I look at the Security.framework in my project, SecRandom.h (which is where those two things are documented as being declared in) is not included in the list of files. I found it in the file system, at /Developer/Platforms/ iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/System/Library/ Frameworks/Security.framework, but when I try to add *this* framework to the project, Xcode *actually* adds /Developer/Platforms/ iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.2.1.sdk/ System/Library/Frameworks/Security.framework instead. This latter location is where all the other frameworks (Foundation.framework, CoreGraphics.framework, et al.) in the project live, but that Security.framework does not contain SecRandom.h. Is this a situation where it works only on the device, not the simulator? That would suck rocks.

Custom log file for NSLog
I want to have a custom log file for my app, so that my client can
send it to me when things go different.
In reading the docs for NSLog, it seems that it is just a front-end
for asl. So here's what I thought should work:
directories = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,
NSUserDomainMask, YES);
NSString *logFileName = nil;
int result = 0;
if ([directories count] 0) {
logFileName = [directories objectAtIndex:0];
logFileName = [logFileName stringByAppendingPathComponent:@Logs];
if ([fileMgr createDirectoryAtPath:logFileName
withIntermediateDirectories:YES attributes:nil error:nil]) {
logFileName = [logFileName
stringByAppendingPathComponent:@MyLogFile.log];
int fd = open([logFileName fileSystemRepresentation], (O_RDWR|
O_CREAT|O_TRUNC), (S_IRWXU|S_IRWXG|S_IRWXO));
if (fd != -1) {
result = asl_add_log_file(NULL, fd);
}
}
}
This results in the file being created, but nothing ever being written
to it. In Console.app, I can see the messages when I select All
Messages, Console Messages, and system.log, but *not*
MyLogFile.log.
I assume it has something to do with this comment in the docs for
NSLogv (which NSLog calls): If the STDERR_FILENO file descriptor has
been redirected away from the default or is going to a tty, it will
also be written there. If you want to direct output elsewhere, you
need to use a custom logging facility. This seems contradictory to
the statement that NSLog Logs an error message to the Apple System
Log facility. If anyone would like to educate me on my obvious
misunderstanding of this, I'd appreciate it.
Anyway, I tried it, and yes, redirecting stderr to my log file does
put all my NSLogs into my log file. But, it also prevents the
messages from being seen in Xcode's Console window.
How can I have my cake and eat it too?

You have now just overwritten the previous value of arraySubType, thus
leaking it. You now have a handle to a completely different object,
which is autoreleased. This is why when you do release it, you crash
later.
If you do not use arraySubType between the alloc/init above and this

NSTextView Undo behavior
In my app's window there is an NSTextView, a place in which to enter notes associated with a selected object. Currently, when the user is finished editing those notes and switches to a different view (like clicking in another text area), I capture that edit session and store the new notes by calling -setNotes: on that object; this creates an Undo action, allowing the user to undo the entire edit session in one fell swoop. I had initially turned on the Undo flag in IB for that text view, so that the user could undo (and redo) sub-edits while the edit session was in progress (Undo Typing is pushed onto the Undo stack by the text view, apparently), while my custom Undo action pushed onto the Undo stack would undo the entire edit session itself (Undo Edit Notes). I find when I do this, with the text view's Undo flag enabled, there is some zombie undo action left on the Undo stack, that does nothing, and doesn't go away. Here's the entire process: 1. Select and object and start typing in the Notes field 2. The Edit menu contains Undo Typing, and does just that--reverts the typing while I'm in still in that text view. 3. If I select Undo Typing, that works, and now the Edit menu contains Redo Typing (there is no Undo available, and it is disabled). Redo works, and the Edit menu contains Undo Typing (and Redo is disabled). 4. With changes in the text view, I click a different text area in the window; this action ultimately causes the object's -setNotes: method to be called, in which I set up the Undo action with the current notes and then update the object with the new notes. 5. The Edit menu now contains Undo Edit Notes (Redo is disabled). 6. If I select Undo Edit Notes, the change is reverted; the Edit menu now contains Redo Edit Notes, but also an enabled Undo item. 7. At this point, I can select Undo as long as I have the patience to continue doing so. Nothing (apparent) happens, I never get to the end of the Undo stack, and *my* Redo Edit Notes Undo action remains available. 8. I can select my Redo Edit Notes, and the right thing happens; the Edit menu goes back to Undo Edit Notes (Redo is disabled) and selecting it again takes me back to step 7, ad infinitum. I can only assume this anonymous Undo action is left over from the NSTextView undo stack (since using that is the only way I can get this to appear). Turning off the Undo flag for that text view in IB makes this all go away. I s'pose I could liberally interpret the customer's specification to make my custom Undo action the right thing to do (and eliminate the undo ability whilst editing the field), but that just doesn't sit right with me. But I haven't been able to figure out why this anonymous Undo action is left on the stack, or a good away to get rid of it, or even figure out what happens when I select it. Any ideas?

More on Undo and Redo
I think I must be missing something fundamental, or have a misunderstanding to begin with. Or maybe I'm just doing something wrong to begin with... I'm working on an app, implementing Undo features. Undo basics are simple: you supply the Undo manager an object, a method, and some arguments that effectively mirror the operation just [about to be] performed: when changing a yellow object blue, you pass the Undo manager the object, the -setColor: method, and the current color, so that upon invoking Undo the color is changed back to what it was. Nice and symmetrical. However, I have a case where symmetry is not involved. The program manages cards; it uses custom code to manage the backing store file, which is in a cross-platform format (i.e., it uses open, seek, write, close et al, instead of, say, writing out dictionaries). One of the operations I need to support Undo for is Delete Card. When a card is deleted, the data in the file is deleted, and the GUI removes an entry from the array controller managing the display. In order to support Undo, I cache all the pertinent information that the card would normally hold onto, and upon Undo being invoked, I recreate a new card from scratch. (I cannot hold onto the card object itself because it loads its data lazily; data is not loaded from the file until it actually needs to be displayed on screen. So if I held onto the object itself, some fields would be nil, and once the data is deleted from the file, I can no longer get it back in order to restore it. Not that this is really pertinent to my real question...) I have Undo working just great: I delete a card, I cache its attributes with the Undo manager, it gets deleted from the file, it's removed from the display, I Undo, a new card gets created and populated with the cached attributes, saved in the file and displayed, all is well in the world. The problem is Redo. This is not a symmetric operation, like changing the color of an object on screen. All I need to do to Redo is call the method that deletes the card. It seems I need to tell the Undo manager to invoke a different method, with different arguments, when Redo is invoked, but I've not found how to do that. Anyone care to set me straight on this?

I was told I should be able to disable the animations, but never could, so I ended up writing my own replacement for the IKImageView that behaved correctly.

Getting *my* object out of a tree controller?
I have an NSOutlineView backed by an NSTreeController.
selectedObject = [[treeController selectedObjects] objectAtIndex:n]
gives me back an object (of the type) that I expect. However, when I
then try to find where that object lives in the tree
[treeView rowForItem:selectedObject]
returns -1 (not found). I ultimately need to remove the object from
the tree controller (using -removeObjectAtArrangedObjectIndexPath:
presumably), but how do I get an index path to an object when I have
*just* a pointer to that object? I can get an index path to the
selection, but in this case, the object to be deleted may not actually
be selected in the view. Based on the stuff I discovered below, I
assume I need to be searching for the tree node representation of my
object? How do I get that just from the object itself? Or do I need
to remember that tree node information at the same time I get a handle
to the object?
Thanks!
randy
-
OK, I figured out the following part: NSTreeControllerTreeNode must be
a NSTreeNode, on which I can call -representedObject, which returns me
an object of the type I expect; I left the rest in here in case I'm
mistaken somehow, someone can set me straight.
Even when I query the tree controller directly for its items, I don't
get *my* object types back, but rather NSTreeControllerTreeNodes:
(gdb) po [treeView itemAtRow:1]
NSTreeControllerTreeNode: 0x2a4a00, child nodes {}
(gdb) po [treeView itemAtRow:0]
NSTreeControllerTreeNode: 0x2d82b0, child nodes {
0:NSTreeControllerTreeNode: 0x2a4a00, child nodes {}
1:NSTreeControllerTreeNode: 0x2a4fb0, child nodes {}
}
Not only can I not find any documentation on this type, I can't even
cmd-double-click or search to find *any* mention of it at all.
Casting that to my object type was an exercise in futility (what was
displayed was obviously not a valid object).

Restoring selection to NSOutlineView
Man, I'm feeling dumb today...NSOutlineView/NSTreeController is kicking my butt... I'm trying to determine a sane new selection for when I delete the currently selected item in an NSOutlineView. I'm failing. My thought was to get the index path of the item I deleted, then try to select that same index path, thinking that that would now be the next sibling if there was one, and the selection method would return NO if there was no next sibling (since the index path would be invalid). However, if I've just deleted the last sibling (and thus there is not next sibling), the selection method (-setSelectionIndexPath:) actually returns YES, because instead of *not* changing the selection because the index path is invalid, it changes the selection to nothing because the index path is invalid (thus necessitating the YES return value). If there was no next sibling, I was going to try to select the previous sibling, if there was one, and only if there wasn't, then proceed to select the deleted item's parent (if there was one). But I can't get this far, because of the problem described in the previous paragraph. So, it seems like I need to try to get the actual *object* pointed to by the index path and see if there is a valid object there, but I can't figure out how to do that, either from the NSOutlineView or its backing NSTreeController.

Observing edits make to a table using bindings
Perhaps I just can't get my head around the terminology sufficiently to search on the right thing...feel free to enlighten me. I have an NSTableView, whose content is supplied through bindings to an array controller. Column A is supplied via FieldListController.arrangedObjects.name, Column B via FieldListController.arrangedObjects.value; column B is editable, column A is not. I'm trying to observe when a cell in Column B is edited by [thing addObserver:self forKeyPath:@fieldList options:(NSKeyValueObservingOptionOld | NSKeyValueObservingOptionNew) context:nil]; When I edit a field (by double-clicking it) and commit the edit (pressing Return), in my - observeValueForKeyPath:ofObject:change:context: method, keyPath is fieldList and object is the object that owns the fieldList that is being observed. The NSKeyValueChangeKindKey in the change dictionary is NSKeyValueChangeSetting; NSKeyValueChangeNewKey and NSKeyValueChangeOldKey are both arrays containing all the observed fields in fieldList. But those fields are not the values that are being edited, they are the objects which contain the values that are being edited (i.e., [field value] is what's getting edited (and [field name] is what's displayed in Column A). OK, so all that makes sense, in that I'm observing fieldList, and the notification hands me an array (which is fieldList). However, it doesn't tell me *which* field in the array was edited; I have to iterate over all the fields, comparing the values from old and new to figure out which specific field was edited. I tried changing the observed keyPath to @fieldList.value, but that only succeeded in having the table not display anything at all (which doesn't make sense to me either). Is it possible to know exactly which array element was edited, without registering observers on the entire contents of the array? I figure it has something to do with the keyPath, but the exact something has thus far eluded me.

UTIs and type codes and extensions
I'm just making sure I'm not missing something...
There's no system-defined way to go from a UTI to an old-style file
type code (which the UTI docs seem to refer to as a tag) and back
again, am I correct?
For instance, my app can export files as TIFF, JPEG, or PNG. When the
user makes the selection, I convert the selection popup menu to the
appropriate UTI using the defined constants in UTCoreTypes.h
(kUTTypeTIFF, et al). I'd like to generalize the subsequent code to
take that UTI (public.tiff for example) and convert it to the
appropriate type code ('TIFF'). The next logical step would be
producing a file name extension based on that as well (public.tiff -
tif).
*All* this information is contained in the table at http://developer.apple.com/documentation/Carbon/Conceptual/understanding_utis/utilist/chapter_4_section_1.html#//apple_ref/doc/uid/TP40001319-CH205-CHDIJFGJ
, but I could discern no way to actually do these types of
conversions in a general manner.
History: The reason I need to do this is, Photoshop is brain-dead when
it comes to opening image files that happen to have no extension in
the filename (and no file type code). Preview, QuickTime Player and
GraphicConverter (and sometimes Safari) have NO problem identifying
and opening the exact same files, sans extension, but PS simply says
Could not complete your request because Photoshop does not recognize
this type of file. I am working around this by attaching type and
creator codes to all the image files I export. (Yes, my client could
avoid all this by simply including an extension to the image name, but
old dogs, new tricks, and all that...)
Thanks!

NSTrackingAreas, mouse entered/exited not firing
Yet another simple operation I've apparently managed to miss something with... I have an NSTableView subclass (actually, a subclass of BGHUDTableView), that contains a bunch of custom cells. For a couple types of those cells, I want to switch the cursor while it's in that cell. I'm following the code in the PhotoSearch sample project that's been mentioned here a couple times recently. I've overridden -updateTrackingAreas in my table class, and I can see it adding the correct rect relative to the appropriate view, with options (NSTrackingEnabledDuringMouseDrag | NSTrackingMouseEnteredAndExited | NSTrackingActiveAlways). I've called [[self window] setAcceptsMouseMovedEvents:YES]; from the table subclass's -awakeFromNib. But -mouse[Entered|Exited]: is not being called when I move the mouse into those areas. On a whim I even overrode -acceptsFirstResponder to return YES, but still no joy. Any ideas?

other things.
So, How do you change __MyCompanyName__?
defaults write com.apple.Xcode PBXCustomTemplateMacroDefinitions
'{ ORGANIZATIONNAME = Your Company, Inc.; }'
works (I just tested it again in Xcode 3.1.1).
You have to quit Xcode and *then* run this for it to work, though.

Core Animation glitch
OK, not a good subject line, but I couldn't come up with anything more descriptive. I hope I can explain the issue clear enough...I'm a fair Core Animation newbie... (I know this is long, sorry, but if nothing else, watch the video linked at the end, and see if that rings any bells.) I have integrated the Lemur Flip code (http://tinyurl.com/ 4ftovo*)into my Mac program, to simulate the same sort of view flipping as seen on the iPhone. (See, for example, the Stocks app on the iPhone, when you press the (i) button at the bottom left, and then the Done button.) I reworked it such that it uses my existing views, not using an overlay window like the Lemur Flip code uses. It's working pretty darn good, kudos to Mike Lee for this. Doesn't look quite as good as the animation on the iPhone, but it's still nice. Anyway, the issue crops up *after* this animation finishes. Here's my set up: The 2 views I'm flipping reside in the same parent view (obviously); one view is smaller (maybe 200pix wide by 300 pixels high), the other takes up almost the entire area of the parent view (about 400x500). Also in that parent view is a button that I use to initiate the flip. This button is at the very top of the view hierarchy, drawn on top of everything. However, when the animation flips from the small view to the larger view, the button is no longer drawn. I can still click on where it's supposed to be and it works, it's just not drawn. The weird thing is, the button is visible all the time *during* the animation (as the animation is being rendered behind the button); it's only after the animation completes that it disappears. The - animationDidStop:finished: delegate method that gets called at the end doesn't appear like is should have any affect on my button; in fact, I did not change that code *at*all* from the Lemur Flip sample code. I can enlarge the window, and since the button is bound to the corner of the window, and the animated views are of a fixed size, I can see the button slide out from underneath the large view, even though I can click on it *through* the view! If I take out the section // Although the back layer seemed to rotate forward, in reality it's still flipped. [CATransaction begin]; // Since this is already our assumed state, do not animate this [CATransaction setValue:[NSNumber numberWithBool:YES] forKey:kCATransactionDisableActions]; // Remove all transforms by setting the identity (standard) transform frontView.layer.transform = CATransform3DIdentity; backView.layer.transform = CATransform3DIdentity; [CATransaction commit]; then the button stays drawn on top of everything, as it should, but then, of course, the view is drawn backwards (as indicated by the comments in the code)! Can anyone set me straight on why my button is getting buried beneath a view after the animation, yet is still clickable? Here's a video screen capture I took of it behaving like this: http://www.not-pc.com/CoreAnimationGlitch.mov .

Consistent scroll-to-visible of text view?
I have a table that contains representations of various types of data. As a row is selected another view changes to show details of that data. For instance, some display images and some display text in an NSTextView. As I change from one row to the next, I populate the detail display area with the relevant detail data. When I populate the text view, it was always displaying the text view scrolled to the bottom, presumably because that's where the insert point was left after I inserted the text into the view. Fine, I'll just stick [notesView scrollRangeToVisible:NSMakeRange(0, 0)]; in there, after I insert the text, before it gets displayed. BOOL wasEditable = [notesView isEditable]; [notesView setEditable:YES]; [notesView selectAll:nil]; [notesView insertText:textToDisplay]; [notesView setEditable:wasEditable]; [notesView scrollRangeToVisible:NSMakeRange(0, 0)]; Well, now it alternates between being scrolled to the beginning of the text and being scrolled to the end of the text on subsequent row selections. It'll keep alternating as long as I keep changing the selection. And, it seems to be sensitive to manual scrolling as well: If, when it's scrolled to the top, I manually scroll it to the bottom, change the selection and then come back, the alternating now picks up with it being scrolled to the top again, in an opposite phase. What am I missing to always start the display of this newly-unhidden text view with it scrolled to the top such that the start of the text is always visible?

Funky behavior with layer-backed views
In this one window I have, I have 2 views and 2 buttons, all living in the same parent view (there's more than just that, but these are the relevant bits). The Notes button shows/hides the notes view, and the Info button shows/ hides the MoreInfo view. I have turned on Wants Core Animation Layer for the parent view containing these items, so that I can animate the showing/hiding of them as appropriate. When the Info button is pressed to show the MoreInfo view, I need to hide the Notes button, and I also do this by animating the opacity of the Notes button to 0 and then actually hide it, therefore I need the Wants Core Animation Layer turned on for the parent view. This seems to have a bad side effect: The z-ordering of the Notes button and the MoreInfo view appears to be swapped, but only kind of. What happened before I added this animating was, the Info button is pressed and the MoreInfo view was shown; the MoreInfo view happened to cover the majority of the window, and in fact occupied the space of the Info button, but it was behind the button so that the button was seen overtop the MoreInfo view. Now that I've turned the CA layer on, when the MoreInfo view is shown, it is now covered up *visually* by the MoreInfo view, but the Info button is still clickable, even though it cannot be seen. If I stretch the window wider, the size of the MoreInfo view stays the same, but the button is bound to the corner, so it moves out from under the MoreInfo view. So it's being drawn, but being drawn under the MoreInfo view, but it gets the clicks instead of the MoreInfo view. Does that explanation of what's happening make sense? I tried adding [showInfoBtn display]; in the animationDidStop:finished: delegate method, to try to force the Info button to redraw itself in the correct location, but that had no effect. What is it about CA layering that is causing this, and how do I get my button (which is on top of everything) to actually be *drawn* on top of everything.

Arggg...overrelease in table view cell, but where?
Still fighting with the table view custom cell...sorry for the length
of this, I'm trying to include as much info as I can to help you help
me figure this out.
I have subclassed NSTextFieldCell (NSTFC) so that I can do custom
drawing in my table cells (basically multiple text strings within the
cell). My datasource object maintains an NSMutableArray, which gets
populated each time the user selects a something in the rest of the UI.
-numberOfRowsInTableView: simply returns the number of objects in the
array.
-tableView:objectValueForTableColumn:tableColumn:row: simply returns
the object at index row of the table.
In -tableView:willDisplayCell:aCellforTableColumn:aTableColumn:row:, I
set a couple of instance variables in my NSTFC subclass using
properties that are set to (readwrite, retain), so they are available
in the -drawInteriorWithFrame:inView: method, such as
aCell.cellObject = [tableValues objectAtIndex:rowIndex];.
I have implemented -copyWithZone in my NSTFC subclass as such:
- (id)copyWithZone:(NSZone *)zone
{
MyTableCell *copy = [super copyWithZone:zone];
copy.cellObject = [self.cellObject copy];
copy.gridController = [self.ViewController copy];
return copy;
}
All the rows fit into the visible area of the table (no scrolling).
Everything fine so far?
I can get it to crash by selecting a third row of the table. First
selection, OK; 2nd selection, OK; 3rd selection, boom:
-[GFController release]: message sent to deallocated instance 0x16d97890
Doesn't happen if I select row 1, then 2, and then 1 again; it has to
be 3 different rows.
Here's the stack trace:

#2 0x938c320f in NSPopAutoreleasePool
#3 0x95dc7b8c in -[NSApplication run]
I can also get it to crash with this message: [GFController name]:

Re: Arggg...overrelease in table view cell, but where?
Of course, right after posting I figured something out. If I return a
retained object from -tableView:objectValueForTableColumn:row:, all
the crashes go away. I took out all my extra retains I added in, and
it's still behaving.
But now I'm confused. Based on the standard memory management rules,
I should be returning an autoreleased (or a non-retained?) object,
right? Is the table view doing a release on the value I return, or is
there still something I should be tracking down?
I'm sure I must be missing something, but I sure would like to be
educated.
Thanks.

Still fighting with the table view custom cell...sorry for the
length of this, I'm trying to include as much info as I can to help
you help me figure this out.
I have subclassed NSTextFieldCell (NSTFC) so that I can do custom
drawing in my table cells (basically multiple text strings within
the cell). My datasource object maintains an NSMutableArray, which
gets populated each time the user selects a something in the rest of
the UI.
-numberOfRowsInTableView: simply returns the number of objects in
the array.
-tableView:objectValueForTableColumn:tableColumn:row: simply returns
the object at index row of the table.
In -tableView:willDisplayCell:aCellforTableColumn:aTableColumn:row:,
I set a couple of instance variables in my NSTFC subclass using
properties that are set to (readwrite, retain), so they are
available in the -drawInteriorWithFrame:inView: method, such as
aCell.cellObject = [tableValues objectAtIndex:rowIndex];.
I have implemented -copyWithZone in my NSTFC subclass as such:
- (id)copyWithZone:(NSZone *)zone
{
MyTableCell *copy = [super copyWithZone:zone];
copy.cellObject = [self.cellObject copy];
copy.gridController = [self.ViewController copy];
return copy;
}
All the rows fit into the visible area of the table (no scrolling).
Everything fine so far?
I can get it to crash by selecting a third row of the table. First
selection, OK; 2nd selection, OK; 3rd selection, boom:
-[GFController release]: message sent to deallocated instance
0x16d97890
Doesn't happen if I select row 1, then 2, and then 1 again; it has
to be 3 different rows.
Here's the stack trace:
#0 0x94568907 in ___forwarding___
#1 0x94568a12 in __forwarding_prep_0___
#2 0x938c320f in NSPopAutoreleasePool
#3 0x95dc7b8c in -[NSApplication run]

Re: Table view containing cells with both an image and text

My first inclination is to subclass NSCell and have my subclass manage both a NSImageCell and a NSTextFieldCell.

Then, assuming I am on the right track, is it also then correct that what - (id)tableView:(NSTableView *)aTableView objectValueForTableColumn: (NSTableColumn*)aTableColumn row:(NSInteger)rowIndex would return is what NSCell's setObjectValue gets called with? Can't think of any reason why this wouldn't be the case... Yeah, you are right, that is the case. However, I'd recommend subclassing NSTextFieldCell and having it draw an image. It'll make other stuff work for you automatically (cell expansion tooltips, type selection). See: http://developer.apple.com/samplecode/PhotoSearch/ I'm working through this exact thing right now. Couple things I noticed: - that example uses an NSOutlineView instead of an NSTableView, but close enough, withsome translation... - the cellFrame passed into -drawInteriorWithFrame:inView: is not really the interior of the frame; I've had to do cellFrame.origin.x -= 1, cellFrame.origin.y -= 1, cellFrame.size.width += 3, cellFrame.size.height += 1; to actually completely fill the cell, otherwise I get a white border around the edges (since I'm filling the cell with a custom dark color). I gather I must be doing something wrong, or not doing something I should be, but doing the above completely fills the cell whereas the default value doesn't. One additional question I have (sorry, Eric, don't mean to hijack your thread): in my -drawInterior... method, I draw an attributed string with an NSFont attribute of LucidaGrande-Bold 13.00 pt. P [] (0x16b8c4e0) fobj=0x16b8c450, spc=4.28, however, it sure looks like it's drawing in non-bold, instead. I compared it with a LucidaGrande- Bold 13 point sample in TextEdit, and it's vastly different. I could see something changing behind my back when I simply pass an attributed string back as the object value, but how is that being done when I'm drawing it explicitly? attrs = [NSDictionary dictionaryWithObjectsAndKeys: NSFontAttributeName, [NSFont boldSystemFontOfSize:13.0], NSBackgroundColorAttributeName, [NSColor blackColor], nil]; nameRect = NSInsetRect(cellFrame, 2, 0); attrStr = [[NSAttributedString alloc] initWithString:name attributes:attrs]; [attrStr drawInRect:nameRect]; Screenshot of this (blue) versus TextEdit: http://www.not-pc.com/LucidaGrande-13.png ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Yeah, you don't want to do this; you will have re-draw issues when
the cell is invalidated. It sounds like you want to set the -
intercellSpacing to 0,0, or override the -drawRow/drawRect method
and first fill in the area with a solid background color.
Essentially, what you are doing is undoing the intercell spacing.
OK, I set intercellSpacing to (0,0), take out my hack, and:
(gdb) p (NSSize)[controlView intercellSpacing]
$1 = {
width = 0, height = 0
}
(gdb) p (NSRect)[controlView bounds]
$2 = {
origin = {
x = 0, y = 0
},
size = {
width = 425, height = 460
}
}
(gdb) p (NSRect)aCellFrame
$3 = {
origin = {
x = 0, y = 0
},
size = {
width = 422, height = 18
}
}
Notice the cellFrame is still 3 pixels narrower than the table view
itself.

Custom NSTableView cells
I could use a little guidance, please, on customizing cells for display in an NSTableView. (My app is Leopard-only.) I looked around the Apple docs and cocoadev, but didn't really find anything useful. Other pointers would be appreciated. My table has but one column, but each cell in that column is made up of 2 or more views. I think I have what I need as far as the cells go, but it's feeding them to the table view that's giving me problems. I know the required datasource methods are -numberOfRowsInTableView: and -tableView:objectValueForTableColumn:row:; the first is a no- brainer, the 2nd one stumps me. I assume I must implement -tableView:dataCellForTableColumn:row: to feed the table my custom cells for each row, right? What purpose then does the -tableView:objectValueForTableColumn:row: method serve? What should be returned from that if I'm already feeding ready-made cells from the other one? (This table is not editable, so I do not need to worry about -tableView:setObjectValue) The docs also say that my cells must properly implement - copyWithZone:, but I don't know what properly means in that context.

Drawing a string with a clearColor background

I want the background image to show through the holes in the string I'm drawing. I tried adding [[NSColor clearColor] set]; NSRectFill(textBounds); before the -drawInRect: call, to no avail.

Programmatically adding an NSTableView to another view
I have configured a view .xib with an NSTableView; I load the nib and add the table view to another parent view. I've implemented the necessary delegate and data source methods. It's all working just peachy, except... It's placement in the parent view is wrong, and I can't figure out how to place it correctly. In the .xib file, I've configured all 4 exterior sizing connections to be struts, both interior sizing connections to be springs, for the view, the scrollview, and the table view. [NSBundle loadNibNamed:@FlexViewTable owner:self]; [view addSubview:tableView]; (tableView is an outlet defined in self and connected to File's Owner in the xib; all the connections look right when I view them in gdb) As the tableView fits into the view, it occupies about 90% of the space (there are 2 other views that take up the rest, both above the table). However, there are usually very few rows in the table, and instead of row 0 being towards the top of the view with all the extra space at the bottom of the view, instead, all the rows are compressed towards the bottom of the view, with the last row exactly at the bottom of the view and all the extra space above the table. Row 0 moves up in the view as there are more rows added to the table. Like so: --- -top of view [view header][icon] | | | empty space | | | --- |row0 | |row1 | |row2 | |row3 | |row4 | |row5 | --- -bottom of view I've tried subclassing NSTableView and returning YES from -isFlipped:, but that did nothing (useful). I've tried playing around with the springs and struts in the view xib, but not found the right combination yet. Is there something else I should be doing to move that table up and move the empty space down? I imagine this is going to be another DOH! moment, so feel free in reveling in the moment of pointing out my dumb mistake (it's been a lon day).

Button title irregularities
I am porting an iPhone app to the Mac, and the client desires the exact same look-and-feel on the Mac as they have on the iPhone. So I am doing some custom drawing to achieve that. It's mostly going OK, but I've found myself wasting far too much time on this one little detail, and it's killing me... I'm drawing a button with a custom background, and setting an attributed title on it. There is no border, custom background image for both normal and alternate states, and a title for both normal and alternate states. When I set an attributed title on it, using a custom font, custom paragraph style (necessary to center the title), and a custom color, the text of the title is shifted down 1 pixel when compared to the standard button. Thinking that that 1 pixel difference was due to the different font, I tried again, setting an attributed title that *only* contain the custom color. This time, the title was shifted UP 1 pixel from that of a standard button (2 pixels higher than with the fully attributed title). I tried playing around with the line spacing of the paragraph style, but that made no difference. You can see for yourself in this image: http://www.not-pc.com/Buttons.png . (The custom background was not drawn and the border was added to make it easier to see.) Here's the code I'm using to create the button: button = [NSButton new]; [button setButtonType:NSToggleButton]; [button setBezelStyle:NSRegularSquareBezelStyle/ *NSRoundRectBezelStyle*/]; //[button setBordered:NO]; NSDictionary*attrs; NSMutableParagraphStyle *style = [NSMutableParagraphStyle new]; [style setAlignment:NSCenterTextAlignment]; [style setLineSpacing:10]; attrs = [NSDictionary dictionaryWithObjectsAndKeys: // labelFont, NSFontAttributeName, [NSColor blackColor], NSForegroundColorAttributeName, // style, NSParagraphStyleAttributeName, nil]; [button setAttributedTitle:@Show attributes:attrs]; Is there anything standard I can do to fix this? Yeah, I know 1 pixel isn't that much of a difference, but that's like a 5% error, and it's noticeable. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Interface Builder Wiring Objects

I am trying to learn Cocoa and am having difficulty remembering which direction to CTRL-drag controls to wire up the controls in Interface Builder.

Aaron Hillegass, in his Cocoa Programming for Mac OS X book explains it this way: Now you are going to introduce some objects to each otherTo introduce one object to another, you will control-drag from the object that needs to know to the object it needs to know about. So, for instance, a class needs to know about its NSButton outlet, so you control-drag from the class to the NSButton in the window (to set the IBOutlet). The NSButton needs to know what method to call when it is pressed, so you control-drag from the button to the class (to set the IBAction). Or do what Luke said in his response... :) It seems to me that a button should make a call to my App Controller when the click event is fired; therefore I should CTRL-drag FROM the button TO the NSObject. This would allow me to select the appropriate Received Action (ie, doSomething, etc.). Yep, sounds like you have the basic gist of it... However, if I need to do something with a text box (read from it) and a table view (insert an item), I should go the other way... since I'm going to fetch from the text field and then insert into the NSArray that is feeding the text view. But, what triggers the action of reading from the text field and inserting that into the array that feeds the table (you said text, but I assume that's a typo) view? A button gets pressed? The user presses Enter?
