iCloud超时.(使用iCloud +核心数据+魔法记录

Question

我开始使用app测试Core Data和iCloud(使用Magical Records).在配置Provisioning Profiles和权利很多麻烦后,应用程序最终运行.一段时间后,应用程序崩溃并抛出此消息::

2012-12-31 03:42:07.079 iCloudTest[252:1103] -[PFUbiquitySafeSaveFile waitForFileToUpload:](268): CoreData: Ubiquity:  <PFUbiquityPeerReceipt: 0x1cd5a420>(0)

我使用这种方法来设置核心数据栈:

[MagicalRecord setupCoreDataStackWithiCloudContainer:@"XXXXXXXX.com.gazapps.iCloudTest" localStoreNamed:@"PersonDB.sqlite"];

谁有过这个问题？

Enviroment:
OSX 10.8.2,
Xcode 4.5.2,
app -> iOS 6,
device -> iPhone 4S

是的,比我记得的次数多.

这意味着Core Data的内部结构无法以一种模糊和无证的方式连接到iCloud.没有恢复路径或修复 - 您只需稍后再试.这些错误不是来自Magical Record或您的代码,它们是内部Core Data/iCloud失败.

事情就是这样:这并不意味着你做错了什么.其中的必然结果是,你无法解决它.将iCloud与Core Data一起使用时,有时会发生这种情况,您只需处理它.提交一个错误,并祈祷你相信他们相信的任何神或神,他们有一天会修复它.使用iCloud的核心数据基本上是片状的,你遇到了最疯狂的部分之一.

有时候再次尝试呼叫会有所帮助.但魔法记录会返回void,因此检测代码中的失败并不像您希望的那么简单.

在测试期间,可能有助于从iCloud中删除所有应用程序的数据,以开始清理.您可以在iOS中的设置 - > iCloud - >存储和备份 - >管理存储 - >(此处为您的应用程序名称) - >编辑 - >全部删除.另外,请务必查看http://developer.icloud.com/以查看云中存在的内容.此外,当您遇到问题时,请务必从设备中删除您的应用,以便不会存在旧数据.
