如何在导航控制器内的storyboard中从appdelegate推送viewcontroller

Question

我在我的项目中使用SWRevealViewController,我想在应用程序收到通知时打开一个特定的控制器.我尝试了很多解决方案,但没有任何效果.

我通过使用故事板来关注这个http://www.appcoda.com/ios-programming-sidebar-navigation-menu/.我的故事板设计如下:

当应用程序收到通知时,我想在其导航控制器中加载照片视图控制器.我尝试使用AppDelegate中的以下代码:

UIStoryboard *st = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
    photoViewController *descController = (PhotoViewController*)[st instantiateViewControllerWithIdentifier: @"photoView"];
    UINavigationController *frontNavigationController = [[UINavigationController alloc] initWithRootViewController:descController];
    SidebarTableViewController *rearViewController = (SidebarTableViewController*)[st instantiateViewControllerWithIdentifier: @"menuController"];

    SWRevealViewController *mainRevealController = [[SWRevealViewController alloc]  init];

    mainRevealController.rearViewController = rearViewController;
    mainRevealController.frontViewController= frontNavigationController;
    self.window.rootViewController =nil;
    self.window.rootViewController = mainRevealController;
    [self.window makeKeyAndVisible];

这可行,但创建了一个新的Navigtion控制器,我需要的是使用故事板中已经定义的控制器,因为它具有特定的属性.

任何的想法？

谢谢

实际上SwLRevalViewController取得了所有权Root,所以这样做

在Appdelegate.m

//initially navigate to your Main controller on SWL

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler
{

   NSString *alert = userInfo[@"aps"][@"redirect_url"];
[[NSUserDefaults standardUserDefaults]setObject:alert forKey:@"itemType"];
 [[NSUserDefaults standardUserDefaults]synchronize];
 UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
SWRevealViewController *main = (SWRevealViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:@"SWRevealViewController"];

    self.window.rootViewController = main;
 }

//它会自动重定向到根控制器

在该主视图控制器上ViewDidLoad检查/导航到您的照片视图控制器

        NSString *getType=[[NSUserDefaults standardUserDefaults]objectForKey:@"itemType"];
 if ([gettypeofItem isEqualToString:@"something"])
        {
   yourPhotoViewController *ivc=[self.storyboard instantiateViewControllerWithIdentifier:@"yourPhotoViewController"];

   [self.navigationController pushViewController:ivc animated:YES];
    }
  else

  {

   // do nothing 

  }
