iphone - 像 iPad 上的 iTunes 一样翻转+缩放过渡

Question

我检查了一些其他帖子，发现一些 UIAnimation 过渡提供了执行 Flip+Scale 过渡的解决方案，就像 iPad 上的 iTunes 应用程序一样。但是，我没有得到完全相同的结果。我试过循环 UIView 动画但不起作用。

有人可以对此有所了解吗？

所以我一直在努力，我终于找到了解决方案:)

[UIView animateWithDuration:0.4 delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations:
 ^{
     rect = placeHolderView.frame;

     rect.origin.x += 100;
     rect.origin.y += 70;

     [UIView beginAnimations:nil context:NULL];
     [UIView setAnimationDuration:0.5];
      placeHolderView.frame = rect;
     [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:placeHolderView cache:YES];
     [UIView setAnimationDuration:0.5];
     CGAffineTransform transform = CGAffineTransformMakeScale(3.0, 3.0);
     placeHolderView.transform = transform;

     [UIView commitAnimations];

     self.view.layer.cornerRadius = 5.0f;
     self.view.clipsToBounds = YES;

 } completion:^(BOOL finished) {

         [UIView setAnimationBeginsFromCurrentState:YES];
         [UIView transitionWithView:placeHolderView duration:0.8 options:UIViewAnimationOptionTransitionFlipFromRight|UIViewAnimationOptionBeginFromCurrentState animations:
          ^{
              CGAffineTransform transform = CGAffineTransformMakeScale(10.0, 10.0);
              placeHolderView.transform = transform;
              [UIView beginAnimations:nil context:NULL];
              [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.purchaseItemView cache:YES];
              [placeHolderView setAlpha:0.0];
              [self.myMainView setAlpha:1.0];
              [UIView setAnimationDuration:0.8];
              [UIView commitAnimations];



          } completion:nil];

 }
 ];

placeholderView 是将从一个小的 16x6 图像缩放的视图。而 myMainView 是翻转+缩放过渡结束后显示的视图。希望能帮助任何希望实现这一点的人:)
