问题
Under iOS 6 all my CCMenus appeared centered on the screen by default, if I did not assign an explicit position. Under iOS 7 the menus are positioned off screen.
Do I have to assign an explicit position under iOS 7?

Basically there are two underlying problems.
If you have hidden your status bar under iOS 6, this will not work for iOS 7 without adding an additional value to your Info.plist (View controller-based status bar appearance -> NO)
Due to a bug in Cocos2D your screen size will be calculated wrong, if your status bar is visible.
You have to different options to solve this problem:
- Set a CCMenu position explicitly instead of using the implicit
positioning (e.g:
menu.position = ccp(self.contentSize.width/2, self.contentSize.height/2);) - Set View controller-based status bar appearance -> NO in your Info.plist if you don't want to show the status bar anyway
