Für iOS9,ALAssetsLibrary ist veraltet. Also, wie man es als @ ändePHPPhotoLibrary Anstatt vonALAssets?

if (RecordedSuccessfully && recording == NO) {
    //----- RECORDED SUCESSFULLY -----
    NSLog(@"didFinishRecordingToOutputFileAtURL - success");
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:outputFileURL])
    {
        [library writeVideoAtPathToSavedPhotosAlbum:outputFileURL
                                    completionBlock:^(NSURL *assetURL, NSError *error)
         {
             if (error)
             {

             }
         }];
    }

// Ich habe es versucht, aber es hat nicht funktioniert

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{

        PHAssetChangeRequest* createAssetRequest = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:outputFileURL];

        NSParameterAssert(createAssetRequest);
    }
                                      completionHandler:^(BOOL success, NSError *error) {}];
    }
}
