用相框保存图片到指定相册ios 8

Question

我刚刚使用此代码创建了一个新相册：

 [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^
     {
         //Checks for App Photo Album and creates it if it doesn't exist
         PHFetchOptions *fetchOptions = [PHFetchOptions new];
         fetchOptions.predicate = [NSPredicate predicateWithFormat:@"title == %@", @"ChameleonSensors"];
         PHFetchResult *fetchResult = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAlbumRegular options:fetchOptions];

         if (fetchResult.count == 0)
         {
             //Create Album
             PHAssetCollectionChangeRequest *albumRequest = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:@"ChameleonSensors"];
         }

     }

      completionHandler:^(BOOL success, NSError *error)
     {
         NSLog(@"Log here...");

         if (!success) {
             NSLog(@"Error creating album: %@", error);
         }else{
             NSLog(@"Perfecto");
         }
     }];

没关系，但现在我需要将照片保存到这个相册中。

我正在使用 objective-c 和照片框架。

谢谢

您应该将资产添加到 albumRequest

    //Create Album
    PHAssetCollectionChangeRequest *albumRequest = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:@"ChameleonSensors"];
    PHAssetChangeRequest *createImageRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:[UIImage imageNamed:@"test"]];
    [albumRequest addAssets:@[createImageRequest.placeholderForCreatedAsset]];
