希望这很简单,但我还没能找到修复方法.我有一个应用程序,我正在尝试实现iCloud和Core Data.我希望它可以在iOS7和iOS8上运行.
该应用程序是收藏品的清单/ tableview应用程序.
本质上,该应用程序有一个预先播种的xml文件,其中包含大约50,000个文件. sqlite / core数据最初配置为只有1个项目.用户可以从表视图中选择要添加到核心数据存储的组(以便不包括所有50,000个项目).当用户选择具有1-50个项目的组时,它会解析这些项目的xml并将其写入核心数据存储.当用户选择具有较大文件数量的组时,它会解析并添加它们,但随后在解析过程中也会抛出一些随机的“无文档URL”错误.应用程序不会崩溃,并且似乎添加了所有项目,但应用程序停止与iCloud同步.确切的错误是：

有关如何解决此问题的任何想法？我是否试图同时进行太多更改,这会导致核心数据/ icloud同步崩溃？任何想法或指示将不胜感激.

解决方法
扎克,这不是一个答案(我没有代表评论),但它可能会帮助你走上正确的轨道.我正在实施iCloud核心数据,并且遇到了与iOS 8相同的问题……同样“没有URL的文档”错误(对我来说没有移动错误),以及数据同步中的相同细分.两点意见：
>当我在两台设备上运行我的应用程序时,核心数据同步最初效果非常好……比如几分钟和一些更新.然后我得到“无URL文档”错误.
>我的.sqlite数据库非常小,我想要做的更新是适度的(例如添加一个新的实体),所以我不认为文件大小或更新复杂性是因素.
>在记录这些错误的设备上,商店停止从iCloud导入更改.但我在该设备上所做的更改会继续持续存在于其他设备上.所以效果就像一个单向的崩溃.
希望这可以帮助.非常感谢您所取得的任何进展.几个星期以来,我一直在努力解决这个问题,并且即将放弃并运送应用程序(这是通用的)而没有iCloud数据同步.
