ios-获取原始多点触摸x、y位置

我正在移植一个具有内置专有手势系统的windows touch应用程序，其中一个要求是我必须使用它。该手势系统获取一系列x、y点（每个接触点一个），并从这些原始点推断手势

---

我以前从未在iOS中这样做过，我想知道最好的（唯一的？）方法是什么。

您需要使用触摸屏：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [[event allTouches] anyObject];
    CGPoint touchLocation = [touch locationInView:self];

    touchLocation.x; // x coord
    touchLocation.y; // y coord
}

迅速：

确保ViewController实现UIgestureRecognitzerDelegate:

class MyViewController: UIViewController, UIGestureRecognizerDelegate{...} 

在ViewController内部，覆盖以下内容：

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
    super.touchesBegan(touches, withEvent: event)
    if let touch: UITouch = touches.first as? UITouch{
        let touchLocation = touch.locationInView(self.view) as CGPoint
        touchLocation.x
        touchLocation.y
    }
}
override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {
    //When gesture ends
}
override func touchesMoved(touches: Set<NSObject>, withEvent event: UIEvent) {
    if let touch: UITouch = touches.first as? UITouch{
        let touchLocation = touch.locationInView(self.view) as CGPoint
        touchLocation.x
        touchLocation.y
    }
}

override func touchsbegined（touchs:Set，withEvent-event:UIEvent）{
super.touchsbegind（touchs，withEvent:event）
如果让触摸：UITouch=touch.first as？UITouch{
让touchLocation=touch.locationInView（self.view）作为CGPoint
touchLocation.x
触动位置
}
}
覆盖func touchesEnded（触摸：设置，withEvent事件：UIEvent）{
//手势结束时
}
覆盖功能触摸移动（触摸：设置，withEvent事件：UIEvent）{
如果让触摸：UITouch=touch.first as？UITouch{
让touchLocation=touch.locationInView（self.view）作为CGPoint
touchLocation.x
触动位置
}
}
