Cocos2d unsigned int showing up everywhere

Question

I'm not sure what I did - I was coding away merrily.. I think it might have something to do with updating Xcode to 4.1.1, but all of a sudden, when I build and run my project, the following compiler warning shows up in about 20 different cocos2d modules..

'format specifies unsigned int but the argument has ['CCTimer'] (or whatever module it's in)

the line in question in the cocos2d module is:

return [NSString stringWithFormat:@"<%@ = %08X | target:%@ selector:(%@)>", [self class], self, [target class], NSStringFromSelector(selector)];

and it's the '%08X' that's causing the problem..

And since this error, I can't compile on my iphone, although it runs fine in the simulator. I updated my phone OS to the latest, but it didn't help..

Has anyone else had this?

That's one of many format strings in cocos2d trying to print out the pointer value. While %08X works the correct way to do this is to use %p. So you can change the line to this:

[NSString stringWithFormat:@"<%@ = %p | target:%@ selector:(%@)>", [self class], self, [target class], NSStringFromSelector(selector)];

You will have to change all these lines, there's about a dozen or so of them.

Example output for anyone curious what the difference looks like:

%08X: 0976DC80
%p:   0x976dc80

PS: I have recently fixed all these incorrect cocos2d logs in Kobold2D.
