TouchCollection touchLocations = TouchPanel.GetState(); foreach (TouchLocation touchLocation in touchLocations) { if (touchLocation.State == TouchLocationState.Pressed){} if (touchLocation.State == TouchLocationState.Moved){} if (touchLocation.State == TouchLocationState.Released){} }
获取上一时刻的TouchLocation
TouchLocation previousTouchLocation; bool success = touchLocation.TryGetPreviousLocation(out previousTouchLocation);
TouchLocation的对象拥有Position属性,提供一个相对于屏幕的Vector2对象
