Ios 它没有'；t在didFinishLaunchingWithOptions中加载任何屏幕并崩溃

我在

didfishlaunchingwithoptions

中进行了更改，如果它是从

UILocalNotification

运行的，那么它将在另一个ViewController中运行，但它只是不加载任何内容，并且它的黑屏和应用程序崩溃。代码如下：

UIStoryboard *mainStoryboard;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    mainStoryboard = nil;        
    mainStoryboard = [UIStoryboard storyboardWithName:@"MainIPhone5" bundle:nil];

    UILocalNotification *localNotification = launchOptions[UIApplicationLaunchOptionsLocalNotificationKey];

    if (localNotification) {
        TaskViewController *TaskViewControllerVar;
        TaskViewControllerVar = [mainStoryboard instantiateViewControllerWithIdentifier:@"TaskViewController"];
        self.window.rootViewController = TaskViewControllerVar;
        [self.window addSubview:TaskViewControllerVar.view];
        NSLog(@"1");
    }else{
        RecordingViewController *RecordingViewControllerVar = [[RecordingViewController alloc] init];
        RecordingViewControllerVar = [mainStoryboard instantiateViewControllerWithIdentifier:@"RecordingViewController"];
        self.window.rootViewController = RecordingViewControllerVar;
        [self.window addSubview:RecordingViewControllerVar.view];
        NSLog(@"2");
    }

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    [self.window makeKeyAndVisible];
    return YES;
}

这里是错误

将此代码放在处理本地通知之前

self.window=[[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]]

我花了3天的时间来解决这个问题，谢谢：）
