［分享］iOS開發－view手勢點擊響應

實現view手勢點擊響應

在UIViewController中，加入協議UIGestureRecognizerDelegate，而後.m文件里加入如下代碼：

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

[self.view addGestureRecognizer:singleTap];

　//這個能夠加到任何控件上,好比你只想響應WebView，我正好填滿整個屏幕

singleTap.delegate = self;

singleTap.cancelsTouchesInView = NO;

[singleTap release];

而後有一個關鍵的，要實現一個方法：

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

{    

      return YES;

}

最後，響應的方法中，能夠獲取點擊的座標哦！

-(void)handleSingleTap:(UITapGestureRecognizer *)sender

{   

     CGPoint point = [sender locationInView:self.view]; 

     NSLog(@"handleSingleTap!pointx:%f,y:%f",point.x,point.y);

}
