获取所有相册的列表和每个相册的缩略图

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在某处列出它们，因为它将它们全部显示给用户.拥有相册后，我将如何显示特定相册中所有图像的缩略图?我似乎在文档中找不到任何内容，但我确信一定有办法做到这一点.

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

如果这是您所要求的，您无法从 UIImagePickerController 获取此类信息.

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

看看 AssetsLibrary 框架.甚至还有示例代码 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.
