You can create a custom album and add an image pretty easy with these lines of code in iOS:

// Create the new album.
__block PHObjectPlaceholder *myAlbum;
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
    PHAssetCollectionChangeRequest *changeRequest = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:title];
    myAlbum = changeRequest.placeholderForCreatedAssetCollection;
} completionHandler:^(BOOL success, NSError *error) {
    if (success) {
        PHFetchResult *fetchResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:@[myAlbum.localIdentifier] options:nil];
        PHAssetCollection *assetCollection = fetchResult.firstObject;

        [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
            PHAssetChangeRequest *assetChangeRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:image];

            // add asset
            PHAssetCollectionChangeRequest *assetCollectionChangeRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:assetCollection];
            [assetCollectionChangeRequest addAssets:@[[assetChangeRequest placeholderForCreatedAsset]]];
        } completionHandler:^(BOOL success, NSError *error) {
            if (!success) {
                NSLog(@"Error: %@", error);
            }
        }];
    } else {
        NSLog(@"Error: %@", error);
    }
}];
