Assetslibrary/assetslibrary.h album Get

Ios8.0 previously obtained the album has Uiimagepicker (but only one at a time), if you need to select multiple, you can only customize picker

The framework used here is assetslibrary.framework, resource pool,

#import <AssetsLibrary/ALAsset.h>//Picture basic information

#import <AssetsLibrary/ALAssetsFilter.h>//group Filter, remember that only one

#import <assetslibrary/alassetsgroup.h>//Get albums

#import <assetslibrary/alassetslibrary.h>//the whole class library management class bar

#import <AssetsLibrary/ALAssetRepresentation.h>//images for more information

My side of the simple package, the general process is to get the album first, and then get the photos in the album, relatively simple, directly on the code bar

iOS 8, Apple abandoned the class library, a new photos class, next time to clean up the class library
