Question

I thought UIControlEventTouchCancel is triggered when I tap on a button and then drag out of it. But I’m doing exactly that and my event handler is never called.

I have a class that inherits from UIControl and I’m doing this in the init:

[self addTarget:self action:@selector(onTouchCancel)forControlEvents:UIControlEventTouchCancel];

How do I trigger the cancel event?

Thanks for your help!

Use “UIControlEventTouchUpOutside” if you want an event when the finger is outside the bounds of the control.
