ios - 如何在 iOS 上删除相册？

Question

我正在使用PhotoKit并且我已经创建了一个相册

PHAssetCollectionChangeRequest.creationRequestForAssetCollection(withTitle: RooPhotoAlbum.albumName)

但是我发现第一次将文件保存到相册时出现一些问题所以我需要删除它，以便我可以重现这个问题。如何在 iOS 上以编程方式删除相册？

Answer 1

下面是一个通过错误处理以编程方式删除自定义相册的函数:

func deleteAlbum(albumName: String) {
    let options = PHFetchOptions()
    options.predicate = NSPredicate(format: "title = %@", albumName)
    let album = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: options)

    // check if album is available
    if album.firstObject != nil {

        // request to delete album
    PHPhotoLibrary.shared().performChanges({
        PHAssetCollectionChangeRequest.deleteAssetCollections(album)
    }, completionHandler: { (success, error) in
        if success {
            print(" \(albumName) removed succesfully")
        } else if error != nil {
            print("request failed. please try again")
        }
    })
    } else {
        print("requested album \(albumName) not found in photos")
    }
}

如何使用 -

deleteAlbum(albumName: "YourAlbumName")
