[英]How do I determine the indexPath for cell with a switch that has been tapped?
[英]iOS how to determine if the screen has been tapped
我正在使用iOS 5.x SDK,我想确定屏幕是否被轻按
就目前而言,建立一个NSLog很好,但是我不知道从哪里开始
通常使用手势识别器 ,例如
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapOnView:)];
[self.view addGestureRecognizer:tap];
然后,您将获得如下方法:
- (void)tapOnView:(UITapGestureRecognizer *)sender
{
CGPoint location = [sender locationInView:self.view];
NSLog(@"Tap at %1.0f, %1.0f", location.x, location.y);
}
您可能想从实现touchesBegan:withEvent:
, touchesMoved:withEvent:
, touchesEnded:withEvent:
, touchesCancelled:withEvent:
。
