Load photos

APPhotolibrary *photolibrary = [[APPhotolibrary alloc] init];
[photolibrary loadPhotosAsynchronously:^(NSArray *assets, NSError *error)
{
    if (!error)
    {
        // show assets
    }
    else
    {
        // show error
    }
}];

Sort photos

photolibrary.sortComparator = ^NSComparisonResult(ALAsset *asset1, ALAsset *asset2)
{
    // return result of comparsion two assets   
};

Default sort is by date

Get photo from asset

#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;
}];
