我在使用 CoreData 和 iCloud 时遇到了一些问题。

该应用程序过去运行良好，但一些用户报告数据不再同步。启用调试登录（设置运行时参数 -com.apple.coredata.ubiquity.logLevel 3 ）后，我设法从应用程序中收到一条错误消息：

2012-09-02 11:47:17.835 MyApp[29365:1a0f] -[_PFUbiquityRecordsImporter canProcessTransactionLogWithScore:afterLogWithScore:](364): CoreData: Ubiquity:  <_PFUbiquityRecordsImporter: 0xd692b60>:

    localPeerID: mobile.A9EC2335-92F9-5098-BF24-48D49DD7D170

Can't process log with score: {
    "mobile.A1F36BF9-B200-57C7-9A56-B6993451AA3D" = 4;
    "mobile.A9EC2335-92F9-5098-BF24-48D49DD7D170" = "-58";
} after log with score: {
}
 It is ahead of the local peer.

任何人都知道如何减轻这些错误消息的影响或根本原因是什么；

  • “它领先于当地同行。”
  • “由于不兼容的操作：<_PFUbiquityRecordImportOperation:”

谢谢
