Weird exception after converting to autolayout
I'm getting this happening at certain unpredictable times - I haven't found a repeatable trigger for it, but it only started happening after I switched to autolayout. The ruler views here are in the scroller that hosts my main content view. I have no constraints set on this view at all, though it works normally most of the time other than this problem. Since the problem seems to be with ruler marker images, note that I am supplying some custom images for ruler markers, but again, they seem to be working as expected. Anyone come across this one before, or have any insight into what this is implying? (n.b. '' is my redacted app name) 2014-07-30 19:10:58.654 [5110:303] Overflow allocating bitmap backing store.

I think you're on a wild goose chase here - the most likely explanation to me is that something somewhere is deliberately calling -[NSString boolValue] (and it may not be 'your' code - I wouldn't put it out of the realms of possibility that a call to it sneaked into Sparkle), which didn't exist until 10.5. If this is the problem, and you want to target Tiger, the best solution would be to find the use of boolValue in the code base and replace it with something that will work on 10.4. The category method you made on NSString is not the right solution - it almost certainly does less than the 10.5+ framework implementation, and it'll replace that method when system frameworks call it, which could cause all sorts of problems (this hit me in the past - the SYCK YAML parsing framework implemented -[NSString boolValue], and it caused problems with, of all things, the iPhone keyboard in iPhone OS 3.0).

Under XCode, you select 'run with performance tool' - 'zombies'.
This will launch your app with the 'zombie instrument' attached, that will
signal you if you app tries to message a released entity.
@implementation NSString (MissingMethods)
-(BOOL) boolValue {
return strcmp([self UTF8String], true) == 0;
}
@end
and I don't see any exceptions now. Doesn't it mean the problem is fixed?
What you've done is like putting a band aid over a broken bone. It might cease
bleeding, but you won't go very far anyway.
Dosvedania!

I've created a category and set a breakpoint within this method. Call
stack leads me to NSApplication applicationWillFinishLaunching method,
but what can I do with it? Really, I'm using this delegate method, but
I don't use any boolValue calls there.
Now I've written this one:
@implementation NSString (MissingMethods)
-(BOOL) boolValue {
return [self value] == @true;
}
@end
Because debugger shows just true value, when this method is called.
I have no idea how to switch between OS versions, because this
category is useless (if not worse) in 10.5+, but it does something
useful in 10.4. I can build release with 10.4 SDK, but it will be not
correct, as I believe.
Any ideas?

I've scanned all my project but couldn't find any reference to boolValue. What could cause the problem? Unrecognized selector exceptions are usually caused by memory management bugs. It looks like an NSNumber is getting overreleased somewhere, and its memory is being taken up by an NSString. Since you don't do any -boolValue calls yourself, Keary's thought about bindings is probably correct.

Weird exception
Hi, All, Browsing the console log I've found that my app raises an exception, when it is launched in Mac OS X 10.4. I built it in 10.5 with 10.4 as a target setting. I didn't see any problems there. The exception is caused by unsupported selector calling [NSString boolValue]. I've scanned all my project but couldn't find any reference to boolValue. What could cause the problem? Visually my app is working nice in 10.4. BTW, I'm using Sparkle framework, but AFAIK it is compatible with 10.4. Any ideas? -Thanks ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
