ios - ALAssetsLibrary enumerateGroupsWithTypes :ALAssetsGroupPhotoStream doesn't contain videos in the group

Question

照片流组在过滤视频时返回计数 0。这是要重现的代码:

ALAssetsGroupType groupTypes = ALAssetsGroupPhotoStream;
ALAssetsFilter* assetTypes = [ALAssetsFilter allVideos];
ALAssetsLibrary* library = [[ALAssetsLibrary alloc] init];

ALAssetsLibraryAccessFailureBlock failureBlock = ^(NSError *error)
{
};

ALAssetsLibraryGroupsEnumerationResultsBlock enumGroupsBlock = ^(ALAssetsGroup *group, BOOL *stop)
{
    if (group)
    {
        [group setAssetsFilter:assetTypes];
        NSString* name = [group valueForProperty:ALAssetsGroupPropertyName];
        NSUInteger count = group.numberOfAssets;
        NSLog(@"name: %@, count: %lu", name, (unsigned long)count);
    }
};

[library enumerateGroupsWithTypes:groupTypes usingBlock:enumGroupsBlock failureBlock:failureBlock];

“我的照片流”和“共享流”都会发生这种情况。请注意，照片应用会显示视频。另请注意，过滤照片(使用上面的 [ALAssetsFilter allPhotos])确实有效。我在 iOS 7.1.2 和 8.1 上重现了这个。

有没有其他人看到这个或找到解决方法？谢谢!

更新(2014 年 10 月 29 日):我的照片流不支持视频，只有共享流支持。

Which photo formats does My Photo Stream support?

My Photo Stream supports JPEG, TIFF, PNG, and most RAW photo formats. My Photo Stream doesn't work with video.

在我的 iPhone 上，“我的照片流”相册中没有视频，只有照片。
