如何使用以前的视图控制器中的id将图像保存到单独的相册中

#import <Photos/Photos.h>

- (void)saveImageToAlbum:(UIImage *)image {
    PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
    if (status == PHAuthorizationStatusAuthorized) {
        [self saveImage:image];

            if (status == PHAuthorizationStatusAuthorized) {
                [self saveImage:image];
            }
        }];
    }
}

- (void)saveImage:(UIImage *)image {
    PHAssetCollection *album = [self getOrCreateAlbum];
    if (album) {
        [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
            PHAssetChangeRequest *assetRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:image];

        } completionHandler:^(BOOL success, NSError *error) {
            if (success) {
                NSLog(@"Image saved to album");
            } else {
                NSLog(@"Error saving image to album: %@", error);
            }
        }];
    }
}

    NSString *albumTitle = @"My Album";
    PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
    fetchOptions.predicate = [NSPredicate predicateWithFormat:@"title = %@", albumTitle];
    PHFetchResult *fetchResult = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:fetchOptions];
    
    if (fetchResult.count > 0) {
        return fetchResult.firstObject;
    } else {
