Get list of all photo albums and thumbnails for each album(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.
