xamarin.ios 上的视图之间的翻译动画 [已解决]

Question

我正在尝试在 xamari.ios 上开发，动画包含视图的翻译，当检测到滑动手势时，动画跟随手指，当它从屏幕上抬起时，会出现第二个视图。为了更好地解释，iOS、iMessage 和 Whatsapp 设置的动画（当你返回时）

我正在尝试手动管理视图并对其运动进行编程，但是当我必须将第二个视图连接到目标视图时，我发现很难......与故事板中存在的现有视图..

 public void AnimazioneSwipe(UIView view1, NSObject view2)
    {
        float displayW = (float)DeviceDisplay.MainDisplayInfo.Width; //Ottengo le informazioni del display corrente

        CAKeyFrameAnimation animation = (CAKeyFrameAnimation)CAKeyFrameAnimation.FromKeyPath("transform.translation.x");
        animation.TimingFunction = CAMediaTimingFunction.FromName(CAMediaTimingFunction.Linear);
        animation.Duration = 1;
        animation.Values = new NSObject[]
            {
                NSNumber.FromFloat(0),
                NSNumber.FromFloat(-displayW)
            };

        view1.Layer.AddAnimation(animation, "shake");



        /* CAKeyFrameAnimation animation2 = (CAKeyFrameAnimation)CAKeyFrameAnimation.FromKeyPath("transform.translation.x");
         animation2.TimingFunction = CAMediaTimingFunction.FromName(CAMediaTimingFunction.Linear);
         animation2.Duration = 1;
         animation2.Values = new NSObject[]
             {
                 NSNumber.FromFloat(880),
                 NSNumber.FromFloat(0)
             };



         view2.Layer.AddAnimation(animation2, "shake");*/
    }

谢谢你

我用这段代码解决了，还有待完善……
