您可以将控制器或视图（无论哪个创建手势识别器）设置为UITapGestureRecognizer.
然后在委托中你可以实现-gestureRecognizer:shouldReceiveTouch:.
在您的实现中，您可以测试触摸是否属于您的新子视图，如果是，则指示手势识别器忽略它。类似于以下内容：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    // test if our control subview is on-screen
    if (self.controlSubview.superview != nil) {
        if ([touch.view isDescendantOfView:self.controlSubview]) {
            // we touched our control surface
            return NO; // ignore the touch
        }
    }
    return YES; // handle the touch
}
