Interesting issue. When creating a fresh project from the Xcode templates (with the Hello World label) I can cause the label to spin with this code:
[label runAction:[CCRepeatForever actionWithAction:[CCRotateBy actionWithDuration:1.0 angle:360.0]]];
However, taking that same code, and applying to another project's sprite results in nothing happening. I can set the sprite's rotation manually and it works just fine. It's not just the rotate action. In fact, NO action works on ANY of the sprites.
Why would this be happening?
iPhone SDK 3.2b3, cocos2d 0.9 release
