使用获取资产集合排除 iCloud 共享相册

Question

我正在尝试获取用户照片库中所有相册的列表，不包括任何 iCloud 共享相册。这是我目前使用的代码：

PHFetchOptions *userAlbumsOptions = [PHFetchOptions new];
userAlbumsOptions.predicate = [NSPredicate predicateWithFormat:@"estimatedAssetCount > 0"];
userAlbumsOptions.includeAssetSourceTypes = PHAssetSourceTypeUserLibrary;

PHFetchResult *userAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeSmartAlbumUserLibrary options:userAlbumsOptions];

for (PHAssetCollection *album in userAlbums) {
    [self.albums addObject:album];
}

如果我没理解错的话，userAlbumsOptions.includeAssetSourceTypes 属性应该过滤掉 iCloud 共享相册；但是，它们仍然显示在列表中。谁能建议我可能做错了什么？

Answer 1

一个可能的解决方案：

PHFetchOptions *userAlbumsOptions = [PHFetchOptions new];
userAlbumsOptions.predicate = [NSPredicate predicateWithFormat:@"estimatedAssetCount > 0"];

PHFetchResult *userAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:userAlbumsOptions];

for (PHAssetCollection *album in userAlbums) {
    if (album.assetCollectionSubtype != PHAssetCollectionSubtypeAlbumCloudShared) {
        [self.albums addObject:album];
    }
}

基本上，检索所有资产集合，但仅当子类型不是 PHAssetCollectionSubtypeAlbumCloudShared 时才将它们添加到相册数组中。这行得通，但我对此并不满意。 PHAssetCollectionSubtypeAlbumCloudShared 检查应该没有必要。
