that error is NSManagedObjectMergeError : 该错误是NSManagedObjectMergeError :
Error code to denote that a merge policy failed—Core Data is unable to complete merging.
错误代码表示合并策略失败 - Core Data无法完成合并。
The NSError object may be able to help in decoding this error. NSError对象可能有助于解码此错误。 Can you post the code you are using to insert the new data?
你可以发布用于插入新数据的代码吗?
