NSInternalInconsistencyException未能找到NSManagedObjectModel爲實體名稱

Question

我試圖建立coredata在我已經啓動了一個項目。我去了而其他一些錯誤，但現在已經縮小到這一點，

***終止應用程序由於未捕獲的異常「NSInternalInconsistencyException」，原因是：「+ entityForName：無法 定位NSManagedObjectModel的實體名稱「MANUF」

我想我已經縮小的問題和可能的解答此問題並回答here回覆：亞歷克斯的回答。

但是我不能完全肯定這是對我的情況下，作爲我困惑的原因是不是在我的應用程序，委託& viewcontrollers設置了一切我其實用我的應用程序，委託&一個對象類。所以我希望有人可以幫助我隔離和修復我的問題在這裏...

這是我的對象類中的代碼段給我的問題。它與xcode爲coredata應用程序生成的模板代碼幾乎相同，但它排除了排序和tableview的東西，因爲我不需要..我只是傾銷一堆NSData到我的coredata對象。

- (NSFetchedResultsController *)fetchedResultsController 
{ 
    if (__fetchedResultsController != nil) { 
     return __fetchedResultsController; 
    } 

    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; 
    // Edit the entity name as appropriate. 
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Manuf" inManagedObjectContext:self.managedObjectContext]; //this is the line where my code fails and generates the error in the log 
    [fetchRequest setEntity:entity]; 

    // Edit the section name key path and cache name if appropriate. 
    // nil for section name key path means "no sections". 
    NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:@"Master"]; 
    aFetchedResultsController.delegate = self; 
    self.fetchedResultsController = aFetchedResultsController; 

    NSError *error = nil; 
    if (![self.fetchedResultsController performFetch:&error]) { 
     // Replace this implementation with code to handle the error appropriately. 
     // abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. 
     NSLog(@"Unresolved error %@, %@", error, [error userInfo]); 
     abort(); 
    } 

    return __fetchedResultsController; 
} 

UPDATE：

這就是我想我錯了。在模板代碼控制器和上下文設置這樣

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    // Override point for customization after application launch. 
    UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController; 
    ICDMasterViewController *controller = (ICDMasterViewController *)navigationController.topViewController; 
    controller.managedObjectContext = self.managedObjectContext; 
    return YES; 
} 

中的appdelegate內，因爲我在做我所有的東西在一個對象類，我不知道如何在我的應用程序委託初始化呢？

至於反對什麼，我想在我的appdelegate現在要做的

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    //Add status bar 
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque]; 
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade]; 

    self.window.rootViewController = self.navigationController; //Adds RootViewController to the NavigationController interface 
    self.navigationController.navigationBar.tintColor = [UIColor grayColor]; 
    [self.window makeKeyAndVisible]; 

    //try setting up context for my nsobjectclass EngineResponses 
    EngineResponses *engineResponses = [[EngineResponses alloc] init]; 
    engineResponses.managedObjectContext = self.managedObjectContext; 

    return YES; 
}

上午。

有三件事情我會檢查：

1）是self.managedObjectContextnil？它可能區分大小寫:)

3當您創建協調人），是您正確的模型加載 - 您的模型描述包含一個實體，稱爲Manuf（什麼？你，如果你NSLog(@"%@", self.managedObjectContext);

2獲得）從（2）？
