Does a single rotation gesture event not work?

Question

I am using the following code

recognizer = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(handleRotationFrom:)]; [self.view addGestureRecognizer:recognizer]; [recognizer release]; 

but when I do the one finger rotation event. function handleRotationFrom not called? any help please? I added the delegation method also in my UIView .. any help please?

Answer 1

The rotation gesture always includes two touches. If you want to test it in the iphone simulator, hold down the options key when pressed.
