我正在使用教程編寫一個相當簡單的應用程序。我今天將應用程序複製到我的工作電腦上。它昨天晚上在我的筆記本電腦上完美地工作,但今天我得到這個錯誤。我試着去掉幾乎所有的代碼,甚至刪除了didFinishLaunchingWithOptions函數中的所有內容,但仍然出現此錯誤。我甚至沒有在任何地方聲明navBar!我認爲在代碼之外有一些項目或文件設置是問題所在?由於未捕獲異常'NSUnknownKeyException'而終止應用程序

編輯:這是我的delegate.m文件的頂部。正如你可以看到它是所有的樣板:
#import "LetsEatAppDelegate.h"
//#import "ItemsViewController.h"
@implementation LetsEatAppDelegate
@synthesize window = _window;
@synthesize managedObjectContext = __managedObjectContext;
@synthesize managedObjectModel = __managedObjectModel;
@synthesize persistentStoreCoordinator = __persistentStoreCoordinator;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
[self.window makeKeyAndVisible];
return YES;
}
我刪除了項目中的所有其他文件,仍然得到這個錯誤。
EDIT 2
按照現在的情況,我只能得到我的工作機器上的這個錯誤。完全相同的文件在我的家用筆記本電腦上完美運行相同版本的XCode(4.2.1)
顯示'LetsEat'的代碼。 – zaph
