ios - 使用“hidden = YES”谓词崩溃获取 PHAsset

Question

如文档中所列，PHAsset 支持hidden (or isHidden)获取密钥。但是，当我尝试获取隐藏资产时，我的应用程序因以下日志而崩溃：

*** 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“获取选项中不支持的谓词：隐藏 == 1”

这是示例代码：

PHFetchOptions *options = [[PHFetchOptions alloc] init];
options.wantsIncrementalChangeDetails = YES;
options.includeAllBurstAssets = YES;
options.includeHiddenAssets = YES;
options.predicate = [NSPredicate predicateWithFormat:@"hidden = YES"];

PHFetchResult *fetchResult = [PHAsset fetchAssetsWithOptions:options];

return fetchResult;

Answer 1

我在第一个答案中没有仔细阅读问题，也许这会有所帮助

如果您只想要隐藏的专辑，为什么不使用？子类型：PHAssetCollectionSubtypeSmartAlbumAllHidden

PHFetchOptions *options = [[PHFetchOptions alloc] init];
options.wantsIncrementalChangeDetails = YES;
options.includeAllBurstAssets = YES;
options.includeHiddenAssets = YES;
options.predicate = [NSPredicate predicateWithFormat:@"mediaType == %d",PHAssetMediaTypeImage];

PHFetchResult *albums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeSmartAlbumAllHidden options:nil];
