UIWebView响应单机事件

在UIViewController中，加入协议UIGestureRecognizerDelegate，然后.m文件里加入以下代码：

UITapGestureRecognizer*singleTap =[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleTap];　

//这个可以加到任何控件上,比如你只想响应WebView，我正好填满整个屏幕
singleTap.delegate=self;
singleTap.cancelsTouchesInView =NO;

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

-(void)handleSingleTap:(UITapGestureRecognizer *)sender{
CGPoint point =[sender locationInView:self.view];
NSLog(@"handleSingleTap!pointx:%f,y:%f",point.x,point.y);
}
