Ios CoreData Exc_bad_访问代码=1，带有子实体

我需要你的帮助，我仍然有一个漂亮的

EXC\u BAD\u ACCESS

错误在这行

self.clinic！。复制带DTO（临床医生DTO）

控制台：

po自助诊所

Optional(<NSManagedObject: 0x7a7bd240> (entity: Clinic; id: 0x7a7bbe10 <x-coredata://7B916AD3-1989-426F-932F-0A62C755F2B4/Clinic/p1> ; data: <fault>))

我做错了什么

谢谢；）

编辑：

BaseStoredObject

是

NSManagedObject

的子类，请在数据模型编辑器中检查实体诊所是否指定了正确的类（即诊所）。是的，它是。。最后，我在我的项目中添加了MOGenerator来摆脱这个bug。现在没事了，但我不知道这个问题是什么在数据模型编辑器中检查实体诊所指定了正确的类（ie诊所）。是的，它是。。最后，我在我的项目中添加了MOGenerator来摆脱这个bug。现在没事了，但我不知道这是什么问题
