从iCloud备份中排除文件 [英] Excluding files from iCloud backup

问题描述

我正在使用iOS 5.1 我使用这种和平的代码

I'm using iOS 5.1 I use this peace of code

[pathURL setResourceValue:[NSNumber numberWithBool:YES]
                   forKey:NSURLIsExcludedFromBackupKey
                    error:nil];

我放置内容的文件夹是(在应用沙箱内部).../Library/Application Support/，而不是/Documents文件夹

The folder where I put my content is (inside app sandbox) .../Library/Application Support/, not a /Documents folder

我没有收到任何错误，并且setResourceValue:的结果为是

I do not receive any errors and the result of setResourceValue: is YES

为什么我看到2 MB是设置-> iCloud-> ...等，可以在其中检查应用程序的数据大小?

Why do I see 2 MB is Settings -> iCloud -> ... etc. where I can check the apps data size?

推荐答案

最后，我自己找到了解决方案 提示是将NSURLIsExcludedFromBackupKey应用于根文件夹，而不是应用于要从备份中排除的每个文件

Finally I found the solution by myself The clue is to apply NSURLIsExcludedFromBackupKey to root folder not to every file you want to exclude from backup

因此，一开始，您应该使用库/应用程序支持"文件夹来调用它

so at very beginning you should call this with (for example) "Library/Application Support" folder
