Iphone 在webView中获得联系

我在

UIViewController

上添加

UIWebView

，然后在同一

ViewController

上添加另一个

UIViewController

，然后我想接触

UIWebView
我有一个
UIWebView
作为
UIViewController
视图的子视图。我的解决方案（制表符手势）是：

My
UIViewController
正在通过
UIgestureRecognitizerDelegate
协议实现以下方法（只需重新运行YES）：

你必须加上手势

在.h文件中第一次设置委托

 -(void)ViewDidLoad
   {
          UITapGestureRecognizer   *gesture = [[UITapGestureRecognizer alloc]
       initWithTarget:self action:@selector(HandleGesture:)];
         gesture.delegate=self;
          gesture.numberOfTapsRequired = 1;
         [YourWebview addGestureRecognizer:gesture];
    }
   -(void)HandleGesture:(UITapGestureRecognizer *)sender
    {
        if (gesture.state == UIGestureRecognizerStateEnded)
        {

        }
        if (gesture.state == UIGestureRecognizerStateBegan)
        {
                    // You can write here any action
        }
    }
    - (BOOL)gestureRecognizer:(UITapGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
      // test if our control subview is on-screen
        if ([touch.view isKindOfClass:[UIWebView class]]) {
             // You can handle any thing
            return YES;
         }return NO; // handle the touch
      }

要识别
UIWebview
，
UIScrollview
的触摸事件，您可以使用手势。不要忘记在.h文件中添加
UIgestureRecognitizerDelegate

UITapGestureRecognizer *single = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap)];
    single.numberOfTapsRequired = 1;
    single.delegate = self;
    [webview addGestureRecognizer:single];

-(void)oneTap{
    NSLog(@"single");
}

请注意，手势识别器的触摸是指向视图的，而不是基于页面的。因此，如果你想让你的应用程序响应网页上的某个特定项目，不管它被滚动或缩放到哪里，你最好使用URL方案向你的应用程序发送信号

 -(void)ViewDidLoad
   {
          UITapGestureRecognizer   *gesture = [[UITapGestureRecognizer alloc]
       initWithTarget:self action:@selector(HandleGesture:)];
         gesture.delegate=self;
          gesture.numberOfTapsRequired = 1;
         [YourWebview addGestureRecognizer:gesture];
    }
   -(void)HandleGesture:(UITapGestureRecognizer *)sender
    {
        if (gesture.state == UIGestureRecognizerStateEnded)
        {

        }
        if (gesture.state == UIGestureRecognizerStateBegan)
        {
                    // You can write here any action
        }
    }
    - (BOOL)gestureRecognizer:(UITapGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
      // test if our control subview is on-screen
        if ([touch.view isKindOfClass:[UIWebView class]]) {
             // You can handle any thing
            return YES;
         }return NO; // handle the touch
      }

UITapGestureRecognizer *single = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap)];
    single.numberOfTapsRequired = 1;
    single.delegate = self;
    [webview addGestureRecognizer:single];

-(void)oneTap{
    NSLog(@"single");
}
