安装
将 APPhotolibrary pod 添加到 Podfile
使用
加载照片
APPhotolibrary *photolibrary = [[APPhotolibrary alloc] init];
[photolibrary loadPhotosAsynchronously:^(NSArray *assets, NSError *error)
{
if (!error)
{
// show assets
}
else
{
// show error
}
}];
排序照片
photolibrary.sortAscending = YES;
photolibrary.sortComparator = ^NSComparisonResult(ALAsset *asset1, ALAsset *asset2)
{
// return result of comparsion two assets
};默认排序为日期
从资源获取照片
#import "ALAsset+Photo.h"
...
ALAsset *asset = // assign asset
// photo thumbnail
self.thumbnailImageView.image = asset.photoThumbnail;
// load fullscreen photo (size depends on device screen)
__weak __typeof(self) weakSelf = self;
[asset loadPhotoInFullScreenAsynchronously:^(UIImage *image)
{
weakSelf.fullScreenImageView.image = image;
}];
// load full resolution photo
[asset loadPhotoInFullResolutionAsynchronously:^(UIImage *image)
{
weakSelf.fullScreenImageView.image = image;
}];
