Question

I’m getting an error in an iOS App with Cocos2d. Here it is.

First, I create a Label:

         CCLabelTTF *_alertaGC;

         ...
         ...

        _alertaGC = [CCLabelTTF labelWithString:@"" fontName:@"Marker Felt" fontSize:16];
        _alertaGC.color = ccc3(0, 0, 0);
        _alertaGC.position = [self convertiPad:ccp(110, 220)];
        _alertaGC.anchorPoint = CGPointMake(0.5f, 0.5f);

        [self addChild:_alertaGC z:100];

Pressing a button, I change the string of that label:

...
_alertaGC.string = NSLocalizedString(@"LogFirst", @"Logueate primero");
...

But I’m getting an error when pressing the button. It just happens since I Updated Cocos2d from 0.99 to 2.0rc… So I think something has changed, o something is wrong. It has to be something stupid, but I don’t get it…

Here is the log:

Thank you!

Notice that version 2.0rc is considered unstable for now. I do not have this version but I advise you to simply look in the source code of CCLabelTTF and see how the class methods are declared.
