singleTap.numberOfTapsRequired = 1; 
[self.myWebView addGestureRecognizer:singleTap];

关于点击次数，可以通过属性numberOfTapsRequired设置

例如：

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;
