touchesBegan不适用于UIImageView动画

Question

I'm having some issues over here. I've got a method called

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

for a UIImageView , it works fine while the image is static, the touchesBegan method gets called... but when I make the UIImageView animated, touchesBegan stop working. Any ideas of why this happens?

Answer 1

In order to receive touchesBegan during animations you must include the UIViewAnimationOptionAllowUserInteraction animation option when creating your animation. There is a good discussion here about it.
