Question

我使用iCloud存储iPad应用的核心数据信息。我使用Magical Record提供的帮助方法来处理与Core Data相关的所有内容。

昨天我的应用程序在访问Core Data时开始表现得很奇怪。即使数据库完全为空（应用程序的干净安装），应用程序也会完全冻结并花费大量时间加载。等了好几分钟之后会发出一个错误，说iCloud超时了。出现以下错误：

我读过几篇帖子说iCloud表现得很奇怪，最好只是试着等。这就是我所做的，当我今天18小时后尝试或多或少地发生同样的事情时。

首先，当我启动应用程序时，它给了我另一个错误。启动应用程序时会发生这种情况，因为我在-application:didFinishLaunchingWithOptions:中配置了Core Data和iCloud。我收到以下错误：

}

现在，在尝试了论坛上提到的几个解决方案后（例如，清理构建，重新安装应用程序，删除iCloud数据等），我收到的错误与昨天相同。

我真的无法弄清楚为什么会这样。我不记得用iCloud配置做了什么。我已经更新了我的数据模型，但是在完成应用程序的干净安装，删除所有以前的iCloud数据后，这应该不重要。

我希望有人可以帮助我更接近发生这些错误的原因。

现在这似乎是iCloud的一个已知问题。它一直在使用CoreData和iCloud为我的应用程序间歇工作。很多错误域= NSCocoaErrorDomain代码= 512“文件上传超时。”它可能与您的应用程序完全无关，而与iCloud服务器有关。我一直在关注开发者论坛上的一个帖子，指出它在Apple方面是错误的。（至少自2003年12月30日以来的问题）以下是讨论：
