UIWebView的手势

直接在UIWebView添加手势是没有反应的。需要实现一个代理方法。
1.给webView添加手势

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handle)];
                tap.delegate = self;
                [webView addGestureRecognizer:tap];

2.遵守协议UIGestureRecognizerDelegate，实现代理方法

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
    return YES;
}

3.点击事件的处理

-(void)handle{
// 打开自带浏览器
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.baidu.com"]];
}
