获取每张专辑的所有相册和缩略图列表 [英] Get list of all photo albums and thumbnails for each album

问题描述

如何获取iOS中所有相册的列表？我知道图像选择器必须有一个列表，因为它将它们全部显示给用户。一旦我有了相册，我将如何显示特定相册中所有图像的缩略图？我似乎无法在文档中找到任何内容，但我确信必须有一种方法可以做到。

How do I get a list of all the photo albums in iOS? I know the image picker has to have a list of them somewhere since it displays them all to the user. Once I have the photo albums, how would I go about displaying thumbnails of all the images in a particular album? I can't seem to find anything in the docs, but I'm sure there's got to be a way to do it.

推荐答案

你不能从 UIImagePickerController 那里得到那种信息，如果这就是你要问的。

You can't get that kind of information from UIImagePickerController if that is what you are asking.

Take查看 AssetsLibrary 框架。甚至有示例代码实现自定义图像选择器。

Take a look at AssetsLibrary framework. There is even sample code that implements a custom image picker.
