How to get videos using ALAssetsLibrary in iOS?

Question

Tarun Kumar · Answer

For getting videos ALAssetsFilter class is very helpful during enumeration on group,
Here is an example:

ALAssetsLibrary* library = [[ALAssetsLibrary alloc] init];
[library enumerateGroupsWithTypes:ALAssetsGroupAll usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
    if(group){
        [group setAssetsFilter:[ALAssetsFilter allVideos]];
        [group enumerateAssetsUsingBlock:^(ALAsset *asset, NSUInteger index, BOOL *stop){
            if (asset){
                NSDictionary *meta = [[asset defaultRepresentation] metadata];
            }
        }];
    }
} failureBlock:^(NSError *error) {
    NSLog(@"Enumerating problem with AssetLibrary groups %@", error);
}];

We can also filter allPhotos, allAssets instead of allVideos.
