Appdelegate から別のビュー (タブビュー) に移動する方法。私はこれを試しました

  MyViewController *mvc = [[MyViewController alloc] init];
  UINavigationController *navController = [[[UINavigationController alloc]  initWithRootViewController:mvc] autorelease];
   self.window.rootViewController = navController;

MyViewControllerに移動しますが、タブバーが非表示になり、そのビューで戻るボタンが機能しません(popView)

tabviewcontroller ではないビューに移動しています (タブ バーのみが非表示になっています)

タブバーの作成にこれを試してください

tabBar_Controller = [[UITabBarController alloc] init];
NSMutableArray *localControllersArray =[[NSMutableArray alloc]initWithCapacity:2];


firstViewController = [[FirstViewController alloc] initWithNibName:@"firstViewController" bundle:nil];
nav = [[UINavigationController alloc] initWithRootViewController:firstViewController];
nav.tabBarItem.title = @"item1";
nav.navigationBar.barStyle = UIBarStyleBlack;
[localControllersArray addObject:nav];
[self setNav:nil];

secondViewController = [[SecondViewController alloc] initWithNibName:@"secondViewController" bundle:nil];
nav = [[UINavigationController alloc]initWithRootViewController:secondViewController];
nav.tabBarItem.title = @"item2";
[localControllersArray addObject:nav];
[self setNav:nil];

tabBar_Controller.viewControllers = localControllersArray;
tabBar_Controller.delegate = self;
tabBar_Controller.selectedIndex = 0;

 self.window.rootViewController = tabBar_Controller;

でこれも試すことができますAppdelegate。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    UIViewController *viewController1 = [[[SPHFirstViewController alloc] initWithNibName:@"SPHFirstViewController" bundle:nil] autorelease];
    UIViewController *viewController2 = [[[SPHSecondViewController alloc]  initWithNibName:@"SPHSecondViewController" bundle:nil] autorelease];
    self.tabBarController = [[[UITabBarController alloc] init] autorelease];
    self.tabBarController.viewControllers = @[viewController1, viewController2];
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}
