Menus with cocos2d

If you intend to use the Menu class in cocos2d, remember that each method used as an invocation target by a MenuItem must take exactly one argument which is going to receive the object that invoked the method. If you don't conform to this, you will see an error message like:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSInvocation setArgument:atIndex:]: index (2) out of bounds [-1, 1]'

Here's a sample method that will work:

- (void) doMenuItemAction: (id) sender;
