Hi, All,
This is my first attempt to deal with Cocoa container class, so I have some
unclear points. I've found one of many tutorials here:
http://www.cocoadev.com/index.pl?NSTableViewDataSource
where it is said, among other, that NSTableView items may be filled out
like this:
- (id)tableView:(NSTableView *)aTableView
objectValueForTableColumn:(NSTableColumn *)aTableColumn
row:(int)rowIndex {
return [[myTableViewArray objectAtIndex: rowIndex]
objectForKey:[aTableColumn identifier]]
}
My specifics is that the data (strings) are delivered by an external
procedure, located out of ObjC stuff, and returning C-style strings. My
table has only one column. My question is, as usual, about memory manager:
May I write something like this:
exern void getString(int row, char *s, int *len);
- (id)tableView:(NSTableView *)aTableView
objectValueForTableColumn:(NSTableColumn *)aTableColumn
row:(int)rowIndex {
char buf[255];
int len;
getString(rowIndex, buf, len);
return [NSString stringWithCString:buf length:len
encoding:NSUTF8StringEncoding];
}
I.e. is it possible to return a NSString without its preliminary retaining?
Or should I add [... retain] to the returning string?
All examples operate by some values, stored in retained structures, like
NSArray. Here my question originates from.
Thanks.

NSTableView: Out-Of-Bounds Array Error on reloadData
Hello Panel--
Ok, this is really annoying me. My app works fabulously on 10.4, but on 10.5,
gives an out-of-bounds array error when I reloadData on a tableView with a
dataSource.
The gist of the code is:
code
-(void)awakeFromNib
{
if ([entryArray count] == 0) addNewEntry; // which it does on app opening
[tableView reloadData] // which should display the new entry but bombs out on
10.5 with an OOB array error and the doc window does not display
}
/code
The entryArray is, of course, the dataSource for the tableView.
Opening a data doc rather than generating a new doc gives the same error, also
on a reloadData elsewhere in the code.
I am assuming I am hitting a bug in 10.4 that was fixed in 10.5, but for the
life of me, I cannot figure out what it may be. Recompiling in 10.5 does not
give me any clues.
What am I missing? If anyone can steer me in the correct direction, I would be
most grateful. Unfortunately, Google has been most unhelpful on this topic.
Thanks in advance,
Kevin

Re: iPhone List? - few questions
If you're trying to use data which has been sms'ed to your user, which is something I've thought about doing before, the only way which I thought it could be done is to register your own url for the application and then have the sms you send include the data in a URL format, eg if your app registered URL is foobar you might have foobar://yourdatahere in the SMS. I believe that you'll then have the opportunity in the SMS screen to click the arrow at the side of the screen and your app will launch with that URL as data and you can process it. I don't think you can get any more automated than that. It also relies on you sending the data in a compatible format. Not totally sure this is related to the UIRequiredDeviceCapabilities though, go hunt around the docs for url or 'phone:' and 'text:', I think those are a couple of the URLs that apple registers for stuff and the documentation is around there.

Outline view bound to an NSTreeController's content shows all children at the top level
Hi all, Subject is pretty self-explanatory. The problem: I don't want that behavior. A little longer explanation: The data is a CoreData entity with a self- referencing children-parent many-to-one relationship, which can go arbitrarily deep. The problem is, when call addChild: or insertChild: instead of only appearing one level down, the new instance appears at the top level as well. Likewise, if I make a child from a node on THAT level, the child appears 3 times, once where it's supposed to be, once in the top level, and once one level below its parent's instance at the top level. I get the feeling there's a simple fix for this, but I can't figure out what it is. If it's relevant, I'm not calling add/insertChild: (is there a difference, BTW?) in code, but rather hooking up a button to the treecontroller directly in IB.

Re: iPhone List? - few questions
The sms: URL on the iPhone only supports phone number, unless if you're willing to go deep into the private API, but you couldn't distribute your app into the App Store. My advice is, better to install some kind of sms application or gateway on your server, so your iPhone app could send the text into the server, and the server will forward the message through sms.

Re: iPhone List? - few questions
Right, but you can register your own url schemes which will launch your app and let it handle the data. I've assumed that the SMS displaying framework will parse out such URLs, realize they are registered and put the correct hotlink into the message to launch your app. On Jul 23, 2009, at 9:55 PM, Jesse Armand wrote: The sms: URL on the iPhone only supports phone number, unless if you're willing to go deep into the private API, but you couldn't distribute your app into the App Store.

[iPhone] Zero opacity causes UIView to go numb
Hi, I *KNOW* this must be something absolutely stupid I'm missing, but I'm stuck with this: I have an UIView that's supposed to display an explanatory overlay image whenever it's touched. When the user lifts the finger, the overlay should fade away. To accomplish this I do the following Inside my OverlayView's init method: self.layer.contents = (id)[UIImage imageNamed:@overlay.png] CGImage]; self.layer.opacity = 0.0; and then, inside the touchBegan: and touchEnded: methods I set the opacity to 1.0 and 0.0 respectively. Now, this doesn't work at all, the view doesn't receive the touchBegan: and touchEnded: methods. But everything works fine if I set the opacity to 0.1 instead of 0.0!! And for instance, when I do this: 1. set opacity to 0.1 in the init call... 2. set opacity to 1.0 in the touchBegan call... 3. set opacity to 0.0 (!!!) in the touchEnded call... all subsequent touches are ignored, touchBegan:, touchEnded:, etc. are never called again. Any help on this is very very much appreciated! Thanks, Sebastian ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSTableView is not updated on [reloadData]
Hi, All,
So, I'm continuing :)
I've connected my NSTableView with AppController (in IB) setting
AppController, as NSTableView's datasource. Then I've added a couple
of methods to the AppController to implement NSTableDataSource protocol:
- (int)numberOfRowsInTableView:(NSTableView *)tableView;
- (id)tableView:(NSTableView *)tableView
objectValueForTableColumn:(NSTableColumn *)tableColumn
row:(int)row;
Also I have a timer in my app, which should recalculate something from
time to time and, as a result of this procedure, table row count (as
well as values) should be updated. onTimer: method is like this one:
- (void)onTimer:(NSTimer*)timer {
//
// here we do some actions, leading to actual changes in the table
content.
//
[myTable reloadData];
}
It all is correct for the first look. Isn't it? Now what is
happening. numberOfRowsInTableView: is called only once, yet before
AppController's awakeFromNib is called. At that moment nothing yet is
initialized (initialization goes in awakeFromNib), so
numberOfRowsInTableView: returns zero.
Nothing happens when [myTable reloadData] is called within onTimer:
procedure. None of delegated methods are called, so my table is always
empty, though new data (of nonzero length) are created.
So, my question is - how to make table view to change its row count
and update the data?
Thanks.

Are you sure
[myTable reloadData];
is being executed? reloadData will cause numberOfRowsInTableView to
be called.

Re: NSTableView: Out-Of-Bounds Array Error on reloadData
Hi Graham-- Thanks for the reply. Sorry about the thumbnail code. I was just trying to get all of my other crap out of the way. The problem is, the reloadData statement is throwing the error and -(id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row -(void)tableView:(NSTableView *)tableView setObjectValue:(id)object forTableColumn:(NSTableColumn *)tableColumn row:(int)row are never even called! This is why this problem is annoying me so much. I am assuming I am hitting a bug in 10.4 that was fixed in 10.5, but for the life of me, I cannot figure out what it may be. Recompiling in 10.5 does not give me any clues. So show us the real datasource code. The -awakeFromNib snippet tells us nothing useful. Your assumption is very unlikely to be the case, since thousands of tables have been working since the release of Leopard without a hoard of angry developers clamouring for blood... Then the other probability is that 10.5 introduced a bug, which I strongly doubt. I'll just have to stare at the code another week and see if anything comes to mind.

Re: iPhone List? - few questions
@ Jesse: Yes the idea is to distribute the App through the AppStore, so I guess I can't go any deeper.

(well that is what its on my mind due that i can't get the data of the incoming sms without leaving my iPhone app ).

Are the 2 different methods of animating messing up each other somehow (even though I've removed the 1st animation)? This is working as expected (for the default case at least). By default a view (or layer) is not redraw when it is resized, but the content is scaled. 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.

since you are looking at all classes but it still seems to be pretty
quick. Here is the quick and dirty routine as it works for me with

that anyone looking for a reasonable way to do this can find it on the
list. Also note that I am looking in the main bundle for my classes
because this is just a prototype. In the real world this would almost
certainly be different bundle. Thanks for the pointers guys.

If the bundle is loaded, you should be able to iterate through all
the classes in the system (using the various routines in the
runtime), and check to see if bundleForClass returns the bundle you
are looking for.
If it hasn't been loaded, you can parse the macho file format and
examine the objective-c sections, but that's a lot of work...

NSSliderCell question
I am employing an NSSliderCell in my table view, and I want to slow down the rate of change or increase the resolution of change using a modifier key like commands as I drag. This is employed in a few audio programs to assist a mixer in fine tuning either volume or pan when mixing. Where do I start? I have bound my NSSliderCell to a NSNumber in my NSObjectController.

Re: iPhone List? - few questions
I have been there before, for a mobile banking project, and they don't want to accept my suggestion to process all of the sms processing (incoming / outgoing) on the server, in order for the iPhone app to communicate with server only. That would provide better user experience, because there's no need to use the carrier-specific features in the iPhone. You can observe CitiMobile for US, see how do they do it, it's just like an internet banking, no need for SMS. In my opinion, iPhone apps shouldn't depend too much on carrier specific features.

Re: NSSliderCell question
Hi,
I am using the following two methods for a scrolling number box which
is essentially a slider in the form of a NSTextField subclass. I have
yet to implement this for my custom sliders but maybe this is a good
starting point for you? When I first dabbled with custom sliders all
I did was override the mouseUp, mouseDown, mouseDragged methods etc
now my custom sliders are subclasses of NSControl rather than NSSlider.
-(void)mouseUp:(NSEvent*)theEvent
{
if(drag) drag = NO;
}
-(void)mouseDragged:(NSEvent*)theEvent
{
float val = [self floatValue];
if(!drag) {
// float start_x = [self convertPoint: [theEvent locationInWindow]
fromView: nil].x;
start_y = [self convertPoint:[theEvent locationInWindow] fromView:
nil].y;
prev_y = start_y;
drag = YES;
};
// key modifier key flags
unsigned int flags;
flags = [theEvent modifierFlags];
float next_y = [self convertPoint:[theEvent locationInWindow]
fromView: nil].y;
float deltaY = (next_y - prev_y) / dragSize;
prev_y = next_y;

val += range * deltaY;
[self checkBounds:val];
[self setFloatValue:val];

Comparing NSImages
We're having problems where the same code is producing corrupt output on certain OS versions but not others. We're trying to track this down, but are running into issues trying to verify intermediate results in the process, in particular NSImage data. Question 1: Is it normal for [NSImage TIFFRepresentation] to differ from release to release on identical images? There are pieces of very basic code [1] that are producing NSImages with different TIFFRepresentations on the same input on the different OSes, so I'm not convinced that's a reliable way to tell whether it's producing the expected output. Question 2: Assuming TIFFRepresentation isn't unique, what's the best practice to verify programmatically, say in a unit test, that the output matches an expected output? Thanks, Benjamin Rister [1] Very basic code: // input is NSImage* img, identical on both OSes (TIFFRepresentation exactly identical) int height = [img size].height; int width = [img size].width; NSBitmapImageRep *imageRep = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:width pixelsHigh:height bitsPerSample:8 samplesPerPixel:3 hasAlpha:NO isPlanar:NO colorSpaceName:NSDeviceRGBColorSpace bytesPerRow:width * 3 bitsPerPixel:24]; NSImage *newImage = [[NSImage alloc] init]; [newImage addRepresentation:imageRep]; [imageRep release]; [newImage lockFocus]; NSRect imgRect = NSMakeRect(0,0,width,height); [img drawInRect:imgRect fromRect:imgRect operation:NSCompositeSourceOver fraction:1.0f]; [newImage unlockFocus]; // output [newImage TIFFRepresentation] is different on the different OSes ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Model index and Array Controller index
I have a simple situation that I can't decide on a good solution to. I have a model object that has an index property. These objects are displayed in a simple table view which should be ordered by index. This is easily done by adding a sort descriptor to the array controller that feeds the tableview. The array controller also implements drag n' drop reordering as per mmalc's Bookmarks example. The problem I'm having is that I can't find a decent way of propagating index changes in the array controller back down to the model. Does anyone have a good method of doing this?

Re: Comparing NSImages
Well, before you worry about release differences, you should probably worry about the NSDeviceRGBColorSpace - if you want consistency between different platforms, I'd think you should be using sRGB, Adobe RGB or similar.

Re: NSSliderCell question
Thanks for your ideas Here is what I did:
Here is what I did. I set up KVO for the variable that I attached to
my NSSliderCell. When I made any changes to the underlying variable,
the obersever method would trigger. When you add an observer you can
retrieve the old and new values from the change dictionary and derive
your new value. I temporary suppressed kvo so the routine didn't
infinitely recurse when I set the value using kvo compliant setters
(look at _ignoreObservation). I also updated the slider using the
setFloatValue method. This constrained the slider as well. Now when I
press the command key, I query the current event using your idea for
getting the current event, [NSApp currentEvent], in my oberve value
method. This works sufficiently for my purposes.

Subtract the test's output image from the reference image, pixel by pixel, and look for any non-zero differences. This assumes compatible representations and no differences introduced by any other image-handling steps (e.g. device-RGB is device-dependent, so can't be assumed to be unvarying). Even so, you might encounter small non-zero differences that originate from outside your code-under-test. If these are larger than +/-1 they could be significant; +/-1 I'd probably accept as within the margin-of-error for rounding. -- GG ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Challenge: Block Main Thread while Work is done, with Timeout
I'd often like to block the main thread while another thread or
process performs a little task, but subject to a short timeout. A few
weeks ago, I was able to achieve this by running the main thread's
run loop while an NSTask completed. But I did this after hours of
experimenting and still don't understand how it works. Today, when I
tried to generalize the code, waiting for a little worker thread
instead of an NSTask, my run loop just gets stuck.
I know the trouble is that, although I have read the NSRunLoop
documentation and related material in the Threading Programming Guide
many times, I just don't understand the magic behind this:
while ([[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode
beforeDate:[NSDate distantFuture]])
{
// do something
}
I know that it only runs when an input source fires, and so I
believe I need to add an input source, but when I try to do that I end
up creating ports and distributed objects, which is obviously wrong.
Below is a little demo project. If you look at the end, in main(),
you'll see that, in Test #1, I start a job with a duration of 1.0
seconds and a timeout of 2.0 seconds. Expected result: The job should
complete and program should continue. Actual result: Run loop never
fires, so the program gets stuck. (In Test #2, I would start a
similar job which ^should^ time out.)
Can anyone show how to fix this?

Jerry Krinock

There's probably a better way to do it, but it only took me a few minutes to dream it up and implement it as above and it works perfectly for me and is quite readable / maintainable. -- I.S. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: iPhone List? - few questions
Well you can't register to listen to SMSes, that hook just doesn't exist. So if you rely on proving who someone is by sending something to a specific phone (ie making use of the telephone companys vast network ability to locate one device with that particular SIM card in it at that point in time anywhere in the world), SMS is kind of about the only way to do it. I took a look to see what happens when you're running an app and an SMS comes in, with a URL on it . it's not totally pretty, you get to option to 'reply', which closes your app, or 'close' which closes the SMS. So the best you could do like that is hit reply, close your app, hit the link in the SMS which opens it up again, you'd need a quick-start app for that. The only other way is to have done the SMS thing way in advance and cached a token on the phone you use at the time direct to the server, but that's not very good security, the token would go with the phone, swap SIM cards and someone else is now you. Gustavo Pizano wrote: @ Jesse: Yes the idea is to distribute the App through the AppStore, so I guess I can't go any deeper. The idea is that in the server there is gonna be a sms application that will send the Authorization code to the registered iPhone that is asking for it, then My app should take that access code and connect to the server, its kinda a 2 step Login system. So if there is gonna be an inpediment, then the sms app in the server will send the sms with the Auth Code, then my iPhone will receive the sms, and the sms app of the iPhone will say Hey you I have a new sms, so now that I have the code, I can just copy-paste it in the access code of my app and do the second part of the authentication. (well that is what its on my mind due that i can't get the data of the incoming sms without leaving my iPhone app ). I dunno how user friendly is to do such a authentication, as you can see we are working with very critical data that requires a strong authentication and data encryption , like a bank sort to speak.

I believe that you'll then have the opportunity in the SMS screen to click the arrow at the side of the screen and your app will launch with that URL as data and you can process it. I don't think you can get any more automated than that. It also relies on you sending the data in a compatible format.

Confusion about Lablel Font Size: 13 or 10 ?
I am writing a genealogy program that provides a variety of forms for entering data from many sources, eg, censuses, marriage registers. Instead of custom designing user input panels for each type of record, I am using a specification file that describes the fields and tool tips needed for each form and then use a custom layout manager to layout a specific user interface panel/dialog for each form on the the fly. In writing this I have discovered that the font used in labels is LucidaGrande with a font size of 13. The value of labels is generally just an NSString which Aqua lays out in LucidaGrande/13. For the layout manager I must calculate the lengths of all the labels to be used on a given form so I can lay them all out together using Apple UI guidelines. To find the sizes of the label text I create an NSAttributedString for each one with the correct font and font size and then ask for the length of this attributed string. This all works and seems to be fine, but I have found something that bothers me a little bit. As mentioned I have discovered that the font size in labels (when created directly from Interface Builder) is 13. However, when using the NSFont method +(CGFloat)labelFontSize the value returned is 10. Before I discovered that the font size used in labels was 13 I was using the labelFontSize when setting up the attributed strings, so things didn't work. My question is. Why are labels rendered at 13 font when the NSFont method labelFontSize returns a value of 10? What deep dark secrets do I still have to learn?

[solved] Outline view bound to an NSTreeController's content shows all children at the top level

The problem is, when call addChild: or insertChild: instead of only appearing one level down, the new instance appears at the top level as well. Likewise, if I make a child from a node on THAT level, the child appears 3 times, once where it's supposed to be, once in the top level, and once one level below its parent's instance at the top level. I get the feeling there's a simple fix for this, but I can't figure out what it is.

Re: [iPhone] Zero opacity causes UIView to go numb
Completely transparent views (opacity 0.0) don't receive touch events - you're not missing anything there. As you have found, a little opacity is enough to catch them again. Depending on what's in your view, you might be able to set the background color to [UIColor clearColor] to get the same effect. Or, maybe you can replace the view you're hiding with another (empty) one that has a transparent background color.

mouse entered/exited in nscollectionviewitem's view
Hi there, I hope someone can help me with this. I have an NSCollectionView set up in IB with a connected NSCollectionViewItem and its View prototype. What I want to do is draw a different colored background for a view in the collection when the user mouses over it. I tried to set it up using tracking areas in the view prototype, but since it's just that - a prototype - the setup code only gets called once and then none of the actually displayed views in the collection handle any of my intended mouse tracking. Could anyone please point me into the right direction where to go on from here? Any help is appreciated.

iPhone: getting the pixel data from a PNG file
Hello, all ... I need to be able to make an iPhone app read a PNG file and retrieve the values of its' pixels. I know that libPNG can do this, but my questions are: 1. does libPNG already exist on the iPhone, or do I need to compile it as a .a and link with it? 2. are there Cocoa Touch or other iPhone APIs to help me do this, maybe without needing to use libPNG?

memory allocation different in simulator and on the iPhone
Hi,
I am working on a animal encyclopedia on iPhone. One of the pages displays
one photo of an animal. When the user swipes the screen the image is
replaced with another one.
This works fine and when tested in the simulator with the Instrument for
Object Allocation, all looks cool.
When I tested on the real iPhone with Instrument, the memory used increases
slowly but constantly so that eventually the application dies.
Here is the method that is doing the image changing (direction means if the
new image should come from left or from right). The class is a
UIViewController
-(void) displayAnimal: (int) animaIndex fromDirection:(int)direction{
crtIndex = animaIndex;
NSString* animalName = [[animalList objectAtIndex:animaIndex] objectForKey:
@name];
NSString* fileName = [[animalList objectAtIndex:animaIndex] objectForKey:
@file];
self.title = animalName;
//remove all the subviews
for (UIView *view in self.view.subviews) {
[view removeFromSuperview];
}
UIView* backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320,
480)];
backgroundView.backgroundColor = [UIColor blackColor];
[self.view addSubview:backgroundView];
[backgroundView release];
UIImage* image = [UIImage imageNamed:fileName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
[image release];
CGRect imageFrame = imageView.frame;
imageFrame.origin = CGPointMake(320*direction,0);
imageView.frame = imageFrame;
[self.view addSubview:imageView];
[UIView beginAnimations: nil context: @identifier];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.5];
imageFrame.origin = CGPointMake(0,0);
imageView.frame = imageFrame;
[UIView commitAnimations];
[imageView release];
}
Can you see anything that is not right? Why is the memory allocation showing
different in simulator and on the iPhone?
Thanks a lot,
Dragos

Re: Text is flipped vertically

Any idea how to reset CGContextRef? Maybe it's a better idea to figure out where you're flipping the context. How are you drawing the text? The text system is extremely sensitive about the flippedness of the views it draws into. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Using the Document Architecture and Reading files one buffer at a time
Actually, I think you'll need to cut in before the file wrapper gets made - it looks like it does load the file content into memory. So, instead, override - (BOOL)readFromURL:(NSURL *)absoluteURL ofType: (NSString *)typeName error:(NSError **)outError and then you can get at the original URL before the file wrapper gets created, and do whatever. Note that NSData has the method + (id)dataWithContentsOfURL:(NSURL *)aURL options:(NSUInteger)mask error:(NSError **)errorPtr and one of the options is NSMappedRead which allows you to memory map the file, or you can get a NSFileHandle using the URL's path, which would be another way to read from the file in sections. --Graham On 24/07/2009, at 1:24 PM, Graham Cox wrote: On 24/07/2009, at 5:46 AM, Korei Klein wrote: I'm trying to use the document architecture in an application that will create documents for some very big files.

You then ask the array controller to -rearrangeObjects. So when do you actually do this, in the drop methods or somewhere more central?
