A framework is not the same thing as a static library, so what do you want? A static library is just code that ends up as part of your app, just like any other source code. A framework has its own bundle, which can be contained within an application's bundle. The framework's resources can be part of the framework bundle rather than the app's bundle (and will usually make sense to organise that way). Frameworks aren't hard to make but they bring some downsides, including greater complexity, potential for namespace collisions, etc. Unless you have a truly reusable piece of code that finds many different applications, there's probably little reason to make a framework. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Size limit on .icns files containing 1024x1024 version in 10.5?
I'm trying to create a retina ready version of my application's icon. The application targets 10.5+. I'm using Uli Kusterer's oldiconutil (https://github.com/uliwitness/oldiconutil) to post process the .icns file I make from a .iconset using iconutil on 10.8. The problem is that if I include a 1024x1024 icon (icon_512x...@2x.png), the icon does not display on 10.5. Finder doesn't display the icon, and when it is opened in Icon Composer on 10.5, it appears to be blank/empty. If I remove this largest size, the icon displays correctly on 10.5. Interestingly, if I substitute a completely different, simpler 1024x1024 image with a much smaller file size (~300K instead of ~1MB), the icon again works fine on 10.5. So it seems that there may be some limit on the file size of the overall .icns file and/or the individual image chunks in a .icns file that when exceeded breaks compatibility with Leopard. Compressing the 1024x1024 image with TinyPNG (http://tinypng.org/) was not enough to fix the problem. It did result in a significantly smaller .icns file before running it through oldiconutil, but the final, JPEG2000 compressed output of oldiconutil was still much larger than the variant using a simpler substitute image, presumably because the more complicated image is simply not as compressible. Has anyone else run into this problem before? Have you found a solution? If I can't figure out a solution, I'll have to just omit a retina ready application icon until I drop support for 10.5.

NSTextFieldCell assertion failure messages?
Can anyone tell me what I ought to be doing in response to the following
message?
*** Assertion failure in -[NSTextFieldCell
_objectValue:forString:errorDescription:],
/SourceCache/AppKit/AppKit-1187.34/AppKit.subproj/NSCell.m:1532
This is cropping up in a table delegate/datasource when I bind: the textField
in an NSTableViewCell to my model object.
Each model object has three fields and any of them may be empty. So in my
tableView:viewForColumn:row: method I set each of the textFields' stringValue:
to @ before binding it to it's object.
- (NSView*) tableView:(NSTableView *)tableView
viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
RSPerson * person = (RSPerson*)[self.personAC.content objectAtIndex:row];
NSTableCellView * cellView = [tableView makeViewWithIdentifier:[NSString
stringWithFormat:@%@Cell,[tableColumn identifier]] owner:self];
cellView.textField.stringValue = @ ;
[cellView.textField bind:@stringValue toObject:person
withKeyPath:[tableColumn identifier] options:nil];
return cellView;
}
Any advice appreciated.

All suggestions here are reduced to an external file (bundle) usage. Just for a case, if you really wish to store any data (non-executable code, like images, etc.) within the executable (regardless of the type: the main project, a static library, a dynamic library) there is a way to do it. But you'll need to know how to use assembler in the Cocoa project. If you know it, this way is for you. I used it in my Windows project, but never in Cocoa. AFAIK, you need to create a .s file and add it to your Xcode sources. Then Xcode will know what to do with this file. And you need to write something like this within the .s file: .text .globl _MyFunc pushl %ebx callL1 jmp L2 .align 1 .byte 0x0,0x1,0x2,0x3,0x4 .byte 0x5,0x6,0x7,0x8,0x9 L1: popl%eax movleax, ebx pushl %eax ret L2: addl5, %ebx movl%ebx,%eax popl%ebx ret As a result, you'll have the address of the embedded information in the eax register. I.e. you just need to create the function declaration like this one: (void *) myFunc(void); and call it. Hope this code is close to correct one, as I never dealt with Mac OS assembler. And please take it into account, that 5, mentioned in the code above, means the size of the jmp L2 instruction, which is five in 32-bit assembler, but it will take nine bytes in the 64-bit one. And of course, I'm talking only about x86/64 assembler. Don't know anything about PowerPC one. The only what is left out is how to fill out the .byte with a useful information. Personally I used a specially written simple utility, transcoding any binary file into the fixed length lines of .byte hex codes. You can use decimal or octal codes too. as far as the assembler allows it.
