再次可可錯誤134100（用於打開商店的模型與用於創建商店的模型不兼容）

Question

我在xcode 6.0.1中創建了一個Core Data模型，然後我開始通過創建一個具有三個提取請求的簡單實體。 我使用了xcode工具。

（抱歉，不能張貼圖片）

RequestTask{ 
String argnames 
String argvalues 
Integer16 type 
String method 
} 

我做了一些基本的測試：創建，讀取，更新和刪除。一切工作正常，直到我得到那個着名的錯誤信息：

編輯：即使第一次創建商店，這個錯誤發生，所以模型如何使用創建不同於打開它的商店幾行後？

reason = "The model used to open the store is incompatible with the one used to create the store"; 

}

我只是用模板代碼鍋核心數據應用與AppleDev一些樣本。

#pragma mark - Core Data stack

     return _managedObjectContext; 
    } 

    NSPersistentStoreCoordinator *coordinator = [self persistentStoreCoordinator]; 
    if (coordinator != nil) { 
     _managedObjectContext = [[NSManagedObjectContext alloc] init]; 
     [_managedObjectContext setPersistentStoreCoordinator:coordinator]; 
    } 
    return _managedObjectContext;

     return _persistentStoreCoordinator; 
    } 

    NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"appbesson.sql"]; 
    //NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"testmodel.sql"]; 

    NSError *error = nil; 
    _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; 

    NSDictionary *options = @{NSMigratePersistentStoresAutomaticallyOption:@YES, NSInferMappingModelAutomaticallyOption:@YES}; 

    if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:@"Default" URL:storeURL options:nil error:&error]) { 
     /*

     [[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil]; 
     NSLog(@"Unresolved error %@, %@", error, [error userInfo]); 
     abort(); 
    } 

    return _persistentStoreCoordinator;

這是有趣的部分：我真的在這裏搜索，在谷歌上，在AppleDevelopper ...我敢肯定我失去了一些東西。

SO我已經嘗試：

• 卸載仿真器上的應用程序+重置模擬器+項目清理並生成
• 手動刪除.sqlite .mom .momd在模擬器上的設備的文件夾
• 創建另一個模型（空）測試，它也不能，所以我已經刪除了關於它的一切
• 嘗試一個真正的iPhone，同樣的問題...

然後在這裏我來了，我很抱歉，如果我錯過了什麼地方已經說，但我想盡問題直接相關和間接相關的有很多......

侮辱都很好，如果你能幫助我。

，我發現它的試驗，但我無法解釋爲什麼... 添加存儲時，只需設置配置零，而不是@「默認」。
