Pop Up Menu in NSTableView
I have a table which has a list of items on which multiple actions can be
performed. Initially, I thought to use check box cells (there are only two
possible actions that can be performed on each item right now - so the list of
columns is manageable) I thought a little further about the problem and it
became apparent to me that, whilst there are only two possible actions right
now, there might be twenty in the future - and, given the limited amount of
space available to the table, twenty columns might become unmanageable.
My idea, and whether it's good or not remains to be seen, is to use an
NSPopUpButtonCell in the NSTableView instead. When an action is selected from
the NSPopUpButtonCell the check mark against its name would be toggled
(multiple selections would be permitted, so multiple items in the menu might
have a check mark next to their names). In this manner, the table would only
have two columns (item and menu) and the whole thing would be far more
manageable.
SO:
Question 1. Is this possible, and am I even using the correct tool to do the
job?
Question 2. Are there any examples of how to achieve what I am trying to do?
At the moment, my code looks like this (nothing is happening yet - I'm just
trying to see if I can get the toggle to work - and I can't):
- (IBAction)cellPreferenceChanged:(id)sender
{
[[sender selectedItem] setState:NSOnState];
}
cellPreferenceChanged is bound to the NSPopUpButtonCell in IB. Oddly, despite
this binding, this code results in [NSTableView selectedItem]: unrecognized
selector sent to instance. Why is this? Surely, since it is the
NSPopUpButtonCell that is bound it should be the NSPopUpButtonCell instance for
the selected row that is sent?
I am utterly perplexed, and clearly grasping the wrong end of the stick. Any
help would be most gratefully received.

Code Signing for Mountain Lion
I'm just updating one of my more useful little tools (Locamatic) so that it is code signed for Mountain Lion. I know in advance that this program won't be suitable for the app store, firstly because it's a Preference Pane and secondly because it schedules shell scripts (packaged within the pref pane) to execute when certain conditions are met (gateway changes). I'd like to code sign it so that users can download it from my website and use it without breaching the default gatekeeper configuration though. I have two questions regarding this: 1. Do the internal shell scripts have to be signed separately (and as a corollary, can shell scripts be signed)? 2. When I sign the preference pane (using codesign) everything appears to be successful. When I verify with codesign, it returns nothing (which I understand to be a good thing). However, when I then download my finished prefpane to my test vm, also with Mountain Lion, it fails to pass GateKeeper (can't be opened because it is from an unidentified developer). What am I doing wrong? Thanks as always, and regards, Pascal ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSDocument window opens - even if the document didn't read properly.
I hope that someone here might be able to help me with a couple of queries.
1. I'm trying to open a document (NSDocument). If the file is good then my
program opens it without problem. If the document fails to parse correctly
then the NSDocument window still opens - but it opens empty. Of course, if
parsing of the document fails then I want the document window not to open at
all. The document data gets read as so and if it fails then I return NO - the
document window still opens though. Can anyone suggest what I might have
missed or messed up?
- (BOOL)readFromData:(NSData *)data ofType:(NSString *)typeName error:(NSError
**)outError
{
BOOL success = NO;
success = [self loadTextViewWithInitialData: data];
if (!success)
{
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory,
NSUserDomainMask, YES);
NSString* URLString = [[[paths objectAtIndex:0]
stringByAppendingString:[self
fileURL].lastPathComponent]stringByAppendingString:@.bad];
NSURL* destinationURL = [NSURL URLWithString:[URLString
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
BOOL success = [[NSFileManager defaultManager] copyItemAtURL:[self
fileURL] toURL:destinationURL error:nil];
}
return success;
}
2. If the document fails to open then I want to copy it to a new location,
with a new extension (see above). This fails. I can't think why!

Uh-oh, if this call failed, you’re returning NO without filling in the error
pointer. This will either blow up or provide a poor message to the user.
Hopefully your -loadTextView… method can report why it failed.
Good point - I've now fixed this. That still doesn't explain why the
window stays open though. When I fix this problem, it doesn't provide an error
message to the user either. Perhaps this is connected to the reason that the
window opens anyway, even if the data can't be read.
NSMutableDictionary *errorDetail = [NSMutableDictionary dictionary];
[errorDetail setValue:@This file is corrupted and could not be read.
forKey:NSLocalizedDescriptionKey];
*outError = [NSError errorWithDomain:NSOSStatusErrorDomain code:1
userInfo:
errorDetail];
if (!success)
{
NSArray* paths =
NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask,
YES);
Cocoa has URL-based methods for this in NSFileManager these days; you should
consider adopting them.
Thank you - I will. But I want to get this working first. By examining the
path provided in the string, I can see that the destination is valid - and I've
used code like this successfully in the past. Is the problem that the file
being copied is also the file that I'm attempting (unsuccessfully) to open? Is
it that there's a temporary lock on the file that prevents it from copying
successfully?
NSString* URLString = [[[paths objectAtIndex:0]
stringByAppendingString:[self
fileURL].lastPathComponent]stringByAppendingString:@.bad];
This is some seriously mangled code. Cocoa provides path
manipulation-specific string routines. USE THEM.
NSURL* destinationURL = [NSURL URLWithString:[URLString
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
This is NOT how you convert from a path to a URL. Use +fileURLWithPath:
instead.
Again, it's worked in the past. I changed it to fileURLWithPath - but the end
result is the same.
BOOL success = [[NSFileManager defaultManager] copyItemAtURL:[self
fileURL] toURL:destinationURL error:nil];
You’ve just stored success into a *new* variable. I’m guessing you wanted to
store it into the existing success variable. Unless you’ve changed the
default compiler settings, the compiler should be warning you here that the
success variable is unused. Compiler warnings are useful. HEED THEM.
I do use the variable - just not in that little example I gave. And rest
assured that I heed all compiler warnings, and deal with them.

Re: Watching a variable in Xcode 4.3
Thanks for your thoughts and advice. I really thought that you might be onto
something with stack overflow page - I tried all the suggestions, cleaned my
project and tried again. Boom! Crash.
I then tried a completely new project and… No luck. Boom and crash again.
Is no one else having this problem with Xcode 4.3.2 on Lion 10.7.3? Am I
really the only one? This is consistently reproducible on both my Macs - a Mac
Pro 4,1 with 12GB RAM and a MacBook Air 2010 with 4GB RAM.
Sadly, I can't see how I can move forward with my project until this Xcode
problem is fixed. Fingers crossed for a quick update or solution :-D

Very odd. And very annoying. I mean, I guess that this does normally work

should happen on both my computers, of very different type, so consistently.

Evadne, I saw that before - sadly, it doesn't seem to work for me.

NSAffineTransform on iOS
I'm trying to write some code for iOS and Wow! I didn't expect it to be so unfamiliar. Kind of like walking into a familiar city, like London, and discovering that everyone is speaking Dutch and no one speaks English. Weird. I'm slowly getting to grips with the differences and similarities - but I'm a bit perplexed by transforms. As I say, I'm writing a tile based game and the following code works very nicely in Mac OS X: NSGraphicsContext *context = [NSGraphicsContext currentContext]; [context saveGraphicsState]; id transform = [NSAffineTransform transform]; [transform translateXBy:NSMidX(tileFrame) yBy:NSMidY(tileFrame)]; [transform concat]; [self drawTile:tileFrame]; [context restoreGraphicsState]; Unfortunately, my iOS version doesn't work. That isn't to say that it crashes - it just doesn't produce the expected output. CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSaveGState(context); CGAffineTransform transform; CGAffineTransformTranslate(transform, CGRectGetMidX(tileFrame), CGRectGetMidY(tileFrame)); CGContextConcatCTM(context, transform); [self drawTile:tileFrame]; CGContextRestoreGState(context); I'm sure that my error will be obvious to anyone who isn't a complete newb, but I am - so it isn't obvious to me!

makeObjectsPerformSelector on a sub class
I'm doing a little development on iOS (but hopefully this will apply equally to Mac OS X, so fingers crossed that someone will be able to help me out here), and I'm having a little bother with makeObjectsPerformSelector. I've created a custom view (which will be a tile in my game) as follows: @interface gameTile : UIView And I've successfully drawn my tiles onto the iOS Simulator screen. Now I want to scramble the state of each of the tiles. In the game controller, I'm using the following code: [[self.view subviews] makeObjectsPerformSelector:@selector(scrambleState)]; I've put a breakpoint in scrambleState - and it never gets called. I'm guessing that 'makeObjectsPerformSelector' fails to work because scrambleState is not a method in UIView. Question is, what do I need to do in order to ensure that this code gets called?

Playing Music in Objective C
My game is playable - so I'm polishing the hell out of it right now.

The music isn't written yet, but I was planning on MP3. The sound effects will most likely be short WAVs. I've investigated OpenAL - and the example that Apple provides is impressively complex. Googling gives a lot of iOS suggestions, but none for Mac OS X. So my question is, if you were me, how would you play music? I'm not interested in surround sound or other fanciness - I just want the music and effects files to play easily. Can anyone point me in the direction of a primer or a short example?

Loading Typeface from NSBundle
I'm trying to load a custom typeface from my application bundle (a TrueType
font of my own design). Hunting around on the web reveals only methods which
are deprecated to the extent of not working under OS X Lion (FMActivateFonts):
#import QD/Fonts.h
---
NSString *fontsFolder = [[NSBundle mainBundle] resourcePath];
if (fontsFolder) {
NSURL *fontsURL = [NSURL fileURLWithPath:fontsFolder];
if (fontsURL) {
FSRef fsRef;
FSSpec fsSpec;
(void)CFURLGetFSRef((CFURLRef)fontsURL, fsRef);
OSStatus status = FSGetCatalogInfo(fsRef, kFSCatInfoNone, NULL,
NULL, fsSpec, NULL);
if (noErr == status) {
FMGeneration generationCount = FMGetGeneration();
status = FMActivateFonts(fsSpec, NULL, NULL,
kFMLocalActivationContext);
generationCount = FMGetGeneration() - generationCount;
if (generationCount) {
NSLog(@app - %@ added %u font file%s, name,
generationCount,
(generationCount == 1 ? : s));
}
}
}
}
My question is (I hope) simple. How does one load fonts from the Application
Bundle in Lion?

OutlineView Wierdness - 'item' not being stored.
I'm trying to populate an OutlineView. I've had success in the past but
now, apparently, I'm unable to do it!
Looking at this code:
- (id)outlineView:(NSOutlineView *)outlineView child:(int)index
ofItem:(id)item
{
if (item == nil)
{
[mailListDict writeToFile:@/test.plist atomically:YES];
item = mailListDict;
}
if ([item isKindOfClass:[NSArray class]])
{
return [item objectAtIndex:index];
}
else if ([item isKindOfClass:[NSDictionary class]])
{
[item writeToFile:@/test2.plist atomically:YES];
return [item objectForKey:[[item allKeys] objectAtIndex:index]];
}
return nil;
}
- (id)outlineView:(NSOutlineView *)outlineView
objectValueForTableColumn:(NSTableColumn *)tableColumn byItem:(id)item
{
if ([[[tableColumn headerCell] stringValue] compare:@Key] ==
NSOrderedSame)
{
id parentObject = [outlineView parentForItem:item] ? [outlineView
parentForItem:item] : mailListDict;
if ([parentObject isKindOfClass:[NSDictionary class]])
{
return [[parentObject allKeysForObject:item] objectAtIndex:0];
}
else if ([parentObject isKindOfClass:[NSArray class]])
{
return [NSString stringWithFormat:@Item %d, [parentObject
indexOfObject:item]];
}
}
else
{
if ([item isKindOfClass:[NSString class]])
{
return item;
}
else if ([item isKindOfClass:[NSDictionary class]])
{
[mailListDict writeToFile:@/test3.plist atomically:YES];
[item writeToFile:@/test4.plist atomically:YES];
return [item objectAtIndex:0];
}
else if ([item isKindOfClass:[NSArray class]])
{
id parentObject = [outlineView parentForItem:item] ?
[outlineView parentForItem:item] : mailListDict;
return [[parentObject allKeysForObject:item] objectAtIndex:0];
}
}
return nil;
}
Test, Test2 and Test3 get written correctly but Test4 is empty. This is
rather frustrating - does anyone have any ideas why item seems to be empty
by the time Test4 is reached?

I'm not sure what the problem is, but the code is a mess, which will
probably explain much of it.
If you can't reduce this method to:
- (id) outlineView:(NSOutlineView*) outlineView
objectValueForTableColumn:(NSTableColumn*) tableColumn byItem:(id) item
{
return [item valueForKey:[tableColumn identifier]];
}
Then your controller design should be looked at and reorganised until you
can. It might mean wrapping up certain elements of your data model into
presentable objects that can be passed to the outline view and treated
consistently. Outline views become ultra-easy when you do this.
I'd also be very wary of writing files in any of these methods, even for
test purposes.

Re: Getting filename in NSDocument readFromData
Sometimes, I find, I get so fixated on one particular solution that I can't see the wood for the trees. Thanks for your response though - it did, at least get me thinking. So, if anyone else has the same (slightly numpty) query, the answer is to forget NSData - remember that we're talking about an NSDocument window. So [self fileURL] will provide the answer. Sorry for wasting your time! -Pascal On 28 Apr 2010, at 19:40, Kyle Sluder wrote: On Wed, Apr 28, 2010 at 11:37 AM, Pascal Harris 45rpmli...@googlemail.com wrote: How do I get the filename of the source document when using NSDocument readFromData?

Getting filename in NSDocument readFromData
How do I get the filename of the source document when using NSDocument
readFromData?
By and large, readFromData works excellently. My app is able to get the NSData
object and process it and all works well. But now I want to write a refinement
which would require my app to pass details (i.e. the file name and path) of
files that it can't understand natively to a helper application (if present).
In order to do this I need to know how to get the filename and path within
readFromData. Given that NSDocument displays the name and path (when command
clicking) of documents that it can read in the window title, this information
is clearly somewhere!
- (BOOL)readFromData:(NSData *)data ofType:(NSString *)typeName error:(NSError
**)outError
{
BOOL success = NO;
success = [self loadTextViewWithInitialData: data]; // I need to either
perform the check and processing here or in loadTextViewWithInitialData
return success;
}
Thanks in advance, Pascal___

OS X Game Programming
I've never programmed games before, although I've got a fair bit of useful OS X utility software under my belt. I've now had a few ideas that I'd like to implement - and I'm stuck at almost the first hurdle. I've managed to create an OpenGL view (by way of experimentation) and chuck a few graphics into it (triangles, circles (well, the closest OpenGL can get to a circle anyway!) and so forth). But I can't work out how to get that OpenGL view to accept keystrokes from my event loop. When it comes to tile based games I'm at a complete loss. Obviously, there are various resources out there (SDL, Blitz etc), but I'd rather not use those because I want to understand the ins and outs of my engine. I've googled and come up with plenty of resources for Windows game programming - but not so many for the Mac. In fact, the only book that approaches what I'm after (with friendly examples) is Pangea Software’s Ultimate Game Programming Guide for Mac OS X - but that's rather out of date. What I really want is something like the excellent guides written by luminaries like Kochan or Hillegass, but focussed on game programming for OS X. Does anyone know if such a guide exists? Failing that, is anyone able to suggest a noddy guide to programming games that I might be able to find on the 'net (because so far my efforts have been rather below par). Sorry to post such a non-technical question - I didn't know who else to ask.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Saving position in NSTextView
Okay, I think I have this kind of sorted (courtesy of this source and, of course, Google) - so if anyone else needs to do this in the future, they can do it with this code: To save position: NSPoint containerOrigin = [textViewLarge textContainerOrigin]; NSRect visibleRect = [textViewLarge visibleRect]; visibleRect.origin.x -= containerOrigin.x; // convert from view coordinates to container coordinates visibleRect.origin.y -= containerOrigin.y; NSRange visibleGlyphs = [[textViewLarge layoutManager] glyphRangeForBoundingRect:visibleRect inTextContainer:[textViewLarge textContainer]]; return visibleGlyphs; To retrieve position: [textViewLarge scrollRangeToVisible:scrollRange]; In these 'examples', of course, the NSTextView being considered is called textViewLarge. I do have one proviso though - and that is that this isn't perfect. If you can guarantee that your NSTextView will always be the same size (xy) and that the size (or font) of the text will never change, then this should work without problems. If, however, you cannot guarantee those things then it'll be a little unreliable. Unreliable isn't good, but I don't have any better ideas so it'll have to do. After all, a bookmark within a few pages of the page you actually want marking is better than no bookmark at all.

If I understand correctly, what you want to be able to determine is the range of text that is currently visible. This can be a bit tricky, since depending on the arrangement of text, the visible text might not be a single contiguous range in the document, but one way to do this is to get the text view's visibleRect, convert it into container coordinates (by subtracting the textContainerOrigin), ask the layout manager for glyphRangeForBoundingRect:inTextContainer:, and convert the resulting glyph range to a character range.

Efficient searching of an NSArray of NSDictionary
I have an application with an NSArray of NSDictionary (with 18 keys) which populates an NSTableView. I am concerned that my method of accessing the contents of my array are sub-optimal and I'm therefore seeking advice from the experts. My current method is to iterate through the array, searching for a match for a particular key. I suspect that there may be a faster way - but I cannot find a tutorial (especially since all the example code seems to have gone AWOL in Snow Leopard). This has come to a particular head because I need to implement an NSSearchField and I would like to be able to search for any instance of a string in any key of any array entry. At this stage I would rather not use Core Data (even if this is the most optimal method) because I don't yet have a manual for it. Help!
