互动白板阻截父视图的tap事件

iOS13.4之后， 互动白板会拦截掉superView的tap事件。
丛原理上看， 白板是WKWebView，理论上来子视图是无法拦截父视图的tap事件的，
但是互动白板就是这么操蛋
于是乎，我开始遍历白板中的所有事件，从中辨别究竟是什么事件拦截掉父视图的tap事件,
经过一番寻找之后

最终锁定UIWebTouchEventsGestureRecognizer， 自己尝试之后发现这个手势有点类似UILongPressGestureRecognizer， 所以可以区分点击和长按

- (void)showGestureRecognizers:(UIView*)view{

    for (UIGestureRecognizer *gesture in view.gestureRecognizers)
    {
        NSLog(@"gesture:%@", gesture);
        if ([gesture.className isEqualToString:@"UIWebTouchEventsGestureRecognizer"]) {
//            r.delegate = self;
            [gesture addTarget:self action:@selector(longPressEvent:)];
        }
    }
     
    for (UIView *v in view.subviews){
        [self showGestureRecognizers:v];

    }

}

- (void)incrementCounter {
    self.counter++;
}
