I just got this after releasing an update:
Thank you for submitting your update to Ballz! - Pro Lite to the App Store. During our review of your application we found it is using private APIs, which is in violation of the iPhone Developer Program License Agreement section 3.3.1; "3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs." While your application has not been rejected, it would be appropriate to resolve this issue in your next update.
The following non-public APIs are included in your application:
touchBegan:withEvent:
touchEnded:withEvent:
touchMoved:withEvent:
If you have defined methods in your source code with the same names as the above mentioned APIs, we suggest altering your method names so that they no longer collide with Apple's private APIs to avoid your application being flagged with future submissions.
Please resolve this issue in your next update to Ballz! - Pro Lite.
Is this a problem with something cocos2d does?
