Assigning to 'id<Delegate>' from incompatible type 'ViewController *const_strong'

At this line :

gameAddViewContoller.delegate=self;

Notice that self is of type ViewController which does NOT conform to the GameAddViewController protocol.

For me what ended up happening is that I wasn't adding the delegate to the @interface on my header file

For example

@interface TheNameOfYourClass : UIViewController <TheDelegatorClassDelegate>

@end

You are putting the < GameAddViewControllerDelegate > in the wrong place. It doesn't go on GameAddViewController, it goes on ViewController.
