删除并重新部署应用程序后，iOS CoreData + iCloud中的错误消息 [英] Error messages in iOS CoreData + iCloud after deleting and redeploying app

问题描述

应用程序从一开始就放在iCloud中，因此我有机会用数据填充它，并看到在其他设备上发生的同步。
但是，在一个设备上删除和重新部署应用程序后，我开始遇到问题。

The application has been put in iCloud since the beginning, so I have the opportunities to fill it with data, and see synchronization happening on other devices. However I am starting to have problems after deleting and redeploying the application on one device only.

特别是，在启动时，现在需要花很多时间：

In particular, at startup, it's taking a lot at this point:

NSLog(@"add coordinator");
if (![__persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error]) {
    NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
    abort();
}
NSLog(@"finish");

我可以在控制台中看到添加协调器，然后它似乎永远处于暂停状态。

I can see "add coordinator" in console, then it seems to be in pause forever. Instead by activating core data logging, I can see that is doing a lot of select and update.

然后，显示每个事务编号的日志错误消息的无限列表：

Then an infinite list of log error messages for each transactionNumber is shown:

CoreData: Ubiquity: Error importing transaction log: <PFUbiquityTransactionLog: 0x1929e350>

然后我说，

推荐答案

苹果工程师回复了我的问题到我在Apple Dev论坛上做的一篇文章，说这是一个已知的bug，已经在即将到来的iOS 6上修复。

An Apple engineer replied me to a post I did on Apple Dev forum, stating that this is a known bug that has been fixed on forthcoming iOS 6.

所以，没有解决方案，并重新启动。
在这一点上，我想我会发货CoreData没有iCloud。

So, there's no solution than scratching all data on devices and start again. At this point, I suppose I will ship with CoreData without iCloud.
