推荐答案

将文件移至从icloud你可以使用下面的代码。

For moving any file to and from icloud you can use this code below.

[[[NSFileManager alloc]init] setUbiquitous:YES itemAtURL:your iCloudURL destinationURL:localDirectoryURL error:&errorsss];

唯一的问题是，如果你要转向icloud，代码应为：

only thing is if you are moving to icloud the code should be :

[[[NSFileManager alloc]init] setUbiquitous:YES itemAtURL:localDirectoryURL destinationURL:your_iCloudURL error:&errorsss];

如果您从iCloud获取到Apps Documents目录

and if you are getting it from iCloud to Apps Documents directory

[[[NSFileManager alloc]init] setUbiquitous:NO itemAtURL:your_iCloudURL destinationURL:localDirectoryURL error:&errorsss];
