if let first = gestureRecognizer as? UITapGestureRecognizer, second = otherGestureRecognizer as? UITapGestureRecognizer {
return false
}
if otherGestureRecognizer.view !== self.view {
return false
}
return true
}
func handleTap(sender: UITapGestureRecognizer) {
}
func handleGesture(sender: UIGestureRecognizer) {
}
}this simple code is always get crash with UITapGestureRecognizer in release mode when handle the tap event.
i don't know what the problem
and i get this error with NSZombieEnabled
