如何将图片保存至自定义分组(11)

                                //should be the last iteration anyway, but just in case
                                return;
                            }
                           
                        } failureBlock: completionBlock];
}

           作者写了一个小demo：CustomAlbumDemo.zip 上面的代码用到了ARC，如果你的工程没有使用ARC，记得做相应处理。

      如何添加分组：

[plain]
[[DataCenter defaultAssetsLibrary] addAssetsGroupAlbumWithName:[alertView textFieldAtIndex:0].text 
                                                   resultBlock:resulBlock 
                                                  failureBlock:nil]; 

            [[DataCenter defaultAssetsLibrary] addAssetsGroupAlbumWithName:[alertView textFieldAtIndex:0].text
                                                               resultBlock:resulBlock
