Like the Photos App shows, all albums > all photos in a particular album > single photo view,

even I need a similar kind of a view. I have used UIImagePickerController and easily go to the second step. However, whenever I select an image, I can not show a slide show kind of a view, as UIImagePicker does not give me that.

I made another view controller , just to display these images in a pagenation form.

But, from the delegate method, didFinishPickingMediaWithInfo, when an image is selected, I get only that image using:

[info objectForKey:UIImagePickerControllerOriginalImage];

How do I know the images next to this image, and before this image, so that I can create a slide show?

查看ALAssetsLibrary的文档。要获取照片库中的图像或视频列表，您将使用对象的enumerateGroupsUsingTypes:usingBlock:failureBlock:方法ALAssetsLibrary。例如，您可以调用此方法，然后当它异步返回图像和视频时，您将为幻灯片视图构建图像数组。

另请查看此 SO 线程。答案显示了如何从 中获取 ALAsset 对象UIImagePickerController，它可以让您找到图像的 URL 和有关它的其他信息。
