ios webView 同时添加单击和长按手势

添加手势代码：

 // 单击的 Recognizer    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapToDo)];    tap.delegate = self;    [theWebView addGestureRecognizer:tap];    //长按    UILongPressGestureRecognizer * longPressGr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressToDo)];    longPressGr.minimumPressDuration = 1.0;    longPressGr.delegate = self;    [theWebView addGestureRecognizer:longPressGr];    // 如果长按确定偵測失败才會触发单击    [tap requireGestureRecognizerToFail:longPressGr];

webView添加tap手势无效果
webView中已经内部集成了点击、滑动等手势，当我们自己新建了一个tap手势，设置代理，添加手势后，仍需要实现允许多个手势并发的代理方法，代码如下：

// 允许多个手势并发- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {    return YES;}
