UIWebview手勢iOS

Question

如何在UIWebview中識別用戶touch,tap & double tap。是否有像觸摸開始等任何代表開始？

Answer 1

這裏是實現單輕叩和雙擊上的WebView

UITapGestureRecognizer *singleTap = [[[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(doSingleTap)] autorelease]; 
singleTap.numberOfTapsRequired = 1; 
[self.myWebView addGestureRecognizer:singleTap]; 


UITapGestureRecognizer *doubleTap = [[[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(doDoubleTap)] autorelease]; 
doubleTap.numberOfTapsRequired = 2; 
[self.myWebView addGestureRecognizer:doubleTap]; 

Answer 2

將下面的代碼3個環節就能解決你的問題

關於抽頭數，你可以將它通過屬性numberOfTapsRequired

如：

UITapGestureRecognizer *myGusture = [[[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(doTap)] autorelease]; 
myGusture.numberOfTapsRequired = 1; //you can change it to any number as per your requirement. 
[self.myWebView addGestureRecognizer:myGusture]; 
[myGusture release]; 
myGusture = nil;
