Answer 1

您可以查看SimpleGestureRecognizers示例项目。

http://developer.apple.com/library/ios/#samplecode/SimpleGestureRecognizers/Introduction/Intro.html

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {

    // Disallow recognition of tap gestures in the button.
    if ((touch.view == button) && (gestureRecognizer == tapRecognizer)) {
        return NO;
    }
    return YES;
}

Answer 2

在斯威夫特：

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
    if touch.view is UIButton {
        return false
    }
    return true
}
