iCloud：如何管理iCloud停用？

[英]iCloud : how to manage iCloud deactivation?

原文 2012-07-17 14:09:25 5 1 iphone/ objective-c/ ios/ icloud

I'm facing a problem concerning the iCloud synchronization process. 我正面临着有关iCloud同步过程的问题。

When a user decide to activate iCloud, the document stored locally in the app sandbox is moved to the local iCloud directory and then the file in the sandbox is deleted. 当用户决定激活iCloud时，将本地存储在应用程序沙箱中的文档移动到本地iCloud目录，然后删除沙箱中的文件。 This is done by the setUbiquitous method. 这是通过setUbiquitous方法完成的。

My problem arise if the user deactivates iCloud in the iPhone settings ( by switching off "iCloud documents and data save" ). 如果用户在iPhone设置中停用iCloud（通过关闭“iCloud文档和数据保存”），我的问题就出现了。 In this case the iCloud directory is no more accessible and the app sandbox is void ( because it was deleted by the setUbiquitous method ). 在这种情况下，iCloud目录不再可访问，并且应用程序沙箱无效（因为它已被setUbiquitous方法删除）。 Therefore, the user lost all it's data... 因此，用户丢失了所有数据......

One solution could be to always maintain a copy of the iCloud file in the app sandbox... but that seems quite a lot of work. 一种解决方案可能是始终在应用程序沙箱中维护iCloud文件的副本......但这看起来相当多。 There should be an easier way to do... Anyone has a better idea/solution ?? 应该有一个更简单的方法......任何人都有更好的想法/解决方案？

Thanks for reading ;) 谢谢阅读 ;）

The files are not actually deleted and will be re-downloaded when iCloud is enabled again. 这些文件实际上并未删除，并且会在再次启用iCloud时重新下载。 Couldn't you just show a message with that information? 难道你不能只显示包含该信息的消息吗？ In a way, that's similar to removing an email account in the settings app. 在某种程度上，这类似于在设置应用中删除电子邮件帐户。 The user probably expects that his/her emails are then deleted from the device, but are still available "in the cloud". 用户可能希望他/她的电子邮件随后从设备中删除，但仍然可以“在云中”使用。
