See ALAssetsLibrary class.

An instance of ALAssetsLibrary provides access to the videos and photos that are under the control of the Photos application.

Code might be something like this

void (^assetEnumerator)(struct ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger index, BOOL *stop) {
    if(result != NULL) {
        NSLog(@"See Asset: %@", result);
    }
    };

    void (^assetGroupEnumerator)(struct ALAssetsGroup *, BOOL *) =  ^(ALAssetsGroup *group, BOOL *stop) {
    if(group != nil) {
            [group enumerateAssetsUsingBlock:assetEnumerator];
    }
    };

    library = [[ALAssetsLibrary alloc] init];
    [library enumerateGroupsWithTypes:ALAssetsGroupAlbum
                       usingBlock:assetGroupEnumerator
                     failureBlock: ^(NSError *error) {
                         NSLog(@"Failure");
                     }];
