工具栏下方的 UIImageView CurlUp 过渡

发布于 2024-10-14 02:36:02 字数 1611 浏览 6 评论 0原文

我目前正在致力于在 iPad 应用程序中实现幻灯片控件。

我想管理图像之间不同类型的过渡，特别是 UIViewAnimationOptionTransitionCurlUp。

我的 ViewController 的 xib 由两个叠加的 UIImageView 组成，两个 UIImageView 上有一个 UIToolbar ，以便为用户提供播放/暂停控制。

它是这样的：在此处输入图像描述

我今天面临这样的问题：当我的两个 UIImageViews 之间发生 CurlUp 转换时，我也看到 UIToolbar （通常位于其他两个视图之上）动画：在此处输入图像描述

这是我的转换代码的样子：

if ([slideshow.images count] <= 1)
{
    return;
}
currentImageIndex = ((currentImageIndex + 1) >= [slideshow.images count]) ? 0 : currentImageIndex + 1;

//imageStackView contains the two UIImageViews bound as IBOutlets from my xib
UIImageView *loadingImageView = [imageViewStack objectAtIndex:1];
loadingImageView.image = [slideshow.images objectAtIndex:currentImageIndex];
UIImageView *currentImageView = [imageViewStack objectAtIndex:0];

[UIView transitionFromView:currentImageView
                    toView:loadingImageView
                  duration:slideshow.duration
                   options:UIViewAnimationOptionTransitionCurlUp
                completion:^(BOOL finished) {
                      UIImageView *swap = [imageViewStack objectAtIndex:0];
                      [self.view bringSubviewToFront:toolbar];
                      [imageViewStack removeObjectAtIndex:0];
                      [imageViewStack addObject:swap];
                      [self scheduleNextAnimation];
        }];

如果您对此有任何想法，请告诉我！

提前致谢！

I am currently working on the implementation of a slideshow control in an iPad application.

I would like to manage different kinds of transitions between the images, particularly the UIViewAnimationOptionTransitionCurlUp.

My ViewController's xib is composed of two superposed UIImageViews, with a UIToolbar over the two UIImageViews in order to give the user a play/pause control.

Here is how it looks like :

I today face the problem that when the CurlUp transition occurs between my two UIImageViews, I see the UIToolbar (which is normally over the two other views) animate as well :
enter image description here

Here is how my transition code looks like :

if ([slideshow.images count] <= 1)
{
    return;
}
currentImageIndex = ((currentImageIndex + 1) >= [slideshow.images count]) ? 0 : currentImageIndex + 1;

//imageStackView contains the two UIImageViews bound as IBOutlets from my xib
UIImageView *loadingImageView = [imageViewStack objectAtIndex:1];
loadingImageView.image = [slideshow.images objectAtIndex:currentImageIndex];
UIImageView *currentImageView = [imageViewStack objectAtIndex:0];

[UIView transitionFromView:currentImageView
                    toView:loadingImageView
                  duration:slideshow.duration
                   options:UIViewAnimationOptionTransitionCurlUp
                completion:^(BOOL finished) {
                      UIImageView *swap = [imageViewStack objectAtIndex:0];
                      [self.view bringSubviewToFront:toolbar];
                      [imageViewStack removeObjectAtIndex:0];
                      [imageViewStack addObject:swap];
                      [self scheduleNextAnimation];
        }];

Please let me know if you have any idea about this !

Thanks in advance !
