Iphone 如何获得任何控制目标c的触摸屏位置？

嗨，我想获得任何控件或任何发生触摸的位置/点

为此，我已经实现了这一点，但我没有得到正确的接触点

   // Create gesture recognizer, notice the selector method
UITapGestureRecognizer *oneFingerTwoTaps =
[[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneFingerTwoTaps)] autorelease];
oneFingerTwoTaps.delegate=self;
// Set required taps and number of touches
[oneFingerTwoTaps setNumberOfTapsRequired:1];
[oneFingerTwoTaps setNumberOfTouchesRequired:1];
[[self view] addGestureRecognizer:oneFingerTwoTaps];

及

当我试图点击任何UIButton、UIImage、UITableView时，它没有给我正确的点击点。我有什么做错了吗？请帮帮我。多谢各位

您的代码将在视图中打印发生触摸的位置。如果你在中间触摸一个50x100大小的按钮，它会打印“点25，50”。

如果要查找UIScreen的触摸位置，必须转换以下值：

 - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {

    CGPoint point = [touch locationInView:touch.view];
    CGPoint pointOnScreen = [touch.view convertPoint:point toView:nil];
    NSLog(@"Point - %f, %f", pointOnScreen.x, pointOnScreen.y);
    NSLog(@"Touch");
    return NO; // handle the touch
}

或者直接获取窗口（屏幕）空间中的坐标：

这是@DrummerB答案的快速版本

// add as property
var tapRecognizer: UIGestureRecognizer! 

// add in viewDidLoad() 
tapRecognizer = UIGestureRecognizer()
tapRecognizer.delegate = self // inherit UIGestureRecognizerDelegate
self.view.addGestureRecognizer(tapRecognizer)

// listen for delegate method
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        let pointOnScreen: CGPoint = touch.location(in: nil)
        print("Point - \(pointOnScreen.x), \(pointOnScreen.y)")
        print("Touch")
        return false
}

//这对我有用。xcode 9.2，ios 11.2

谢谢你，它对我来说很酷。我能得到正确的休息点我能做到的…thanx伙计。。。

 - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {

    CGPoint pointOnScreen = [touch locationInView:nil];
    NSLog(@"Point - %f, %f", pointOnScreen.x, pointOnScreen.y);
    NSLog(@"Touch");
    return NO; // handle the touch
}

// add as property
var tapRecognizer: UIGestureRecognizer! 

// add in viewDidLoad() 
tapRecognizer = UIGestureRecognizer()
tapRecognizer.delegate = self // inherit UIGestureRecognizerDelegate
self.view.addGestureRecognizer(tapRecognizer)

// listen for delegate method
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        let pointOnScreen: CGPoint = touch.location(in: nil)
        print("Point - \(pointOnScreen.x), \(pointOnScreen.y)")
        print("Touch")
        return false
}
