I am trying to use Gestures in a game that I am working on and when I use the following code it is giving me the above error.
UISwipeGestureRecognizer* up = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeUp)];
[up setDirection:(UISwipeGestureRecognizerDirectionUp)];
[self addGestureRecognizer:up];
Please help.
You can only add Gesture Recognizers to views.
The last line in your code should be changed to:
[self.view addGestureRecognizer:up];
