C# 向UIImageView添加翻转动画

我正在尝试向Xamarin中的UIImageView添加翻转动画。翻转动画确实可以工作，但是，它翻转整个根视图。我只希望UIImageView翻转，而不是整个屏幕。以下是我所拥有的：

    back = new UIImageView(UIImage.FromBundle("CardBack.jpg"));
    back.UserInteractionEnabled = true;
    back.Frame = new RectangleF(110, 20, 100, 100);
    RootView.AddSubview(back);

    front = new UIImageView(UIImage.FromBundle("jack.jpg"));
    front.Frame = new RectangleF(110, 20, 100, 100);

用户触摸图像时出现的转换代码如下所示：

    UIImageView.Transition(
        fromView: back,
        toView: front,
        duration: .5,
        options: UIViewAnimationOptions.TransitionFlipFromTop | UIViewAnimationOptions.CurveEaseInOut,
            completion: () => { Console.WriteLine("transition complete"); });

如何翻转UIImageView，而不是整个UIView？

[UIView动画宽度：0.5延迟：0.0选项：UIViewAnimationOptionCurveEaseInOut] 动画：^（无效）{ imageview.transform=CGAffineTransformMakeScale（1，-1）； }

完成：无]

您可以将此代码用于imageview上的翻转动画

[UIView beginAnimations:@"bucketsOff" context:nil];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationDelegate:(id)self];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.ImageView cache:YES];
//animate off screen
[UIView commitAnimations];

AnimationTransition类型包括：

typedef NS_ENUM(NSInteger, UIViewAnimationTransition) {
UIViewAnimationTransitionNone,
UIViewAnimationTransitionFlipFromLeft,
UIViewAnimationTransitionFlipFromRight,
UIViewAnimationTransitionCurlUp,
UIViewAnimationTransitionCurlDown,

})

我不认识Xamarin。。但对于Objective-C，您可以检查或
