如何在webview被連續觸摸10秒後顯示一個視圖？

Question

我在webview中顯示一個pub或一個pdf文件。但我無法檢測到在web視圖上的觸摸。

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 

上述方法，當我接觸到PDF或酒吧file.How的任何文字，我可以檢測其上顯示的PDF或酒吧file.Please幫我out.Thanks web視圖點擊被調用。

這是我的代碼：

- (void)viewDidLoad { 
[super viewDidLoad]; 
NSURL *url = [NSURL URLWithString:@"http://dblog.com.au"]; 
NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
[webView loadRequest:request]; 
UILongPressGestureRecognizer *longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)]; 
longPressGestureRecognizer.minimumPressDuration = 6.0; 
[self.webView addGestureRecognizer:longPressGestureRecognizer]; 
[longPressGestureRecognizer release]; 

} 

- (void)handleLongPress:(UIGestureRecognizer *)gestureRecognizer { 
NSLog(@"Long press detected"); 
} 

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

請檢查一下，我有沒有犯任何錯誤？

嘗試類似：

UILongPressGestureRecognizer *longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)]; 
longPressGestureRecognizer.minimumPressDuration = 10.0; 
[self.webView addGestureRecognizer:longPressGestureRecognizer]; 
[longPressGestureRecognizer release]; 

然後：

- (void)handleLongPress:(UIGestureRecognizer *)gestureRecognizer { 
    NSLog(@"Long press detected"); 
}

補充一點：

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

但按同一地點10秒是一個真的很長時間... defa長按的最大值爲0.4秒。請記住，如果手指被拖動，它不再是一個長按..
