Question

I’m new in iPhone, I created application that is started with UITabbarController with 4 items using AppDelegate. through the app I opened some views and I want to relaunch the AppDelegate again by using a code like:

[appdelegate presentModalViewController:myNavController animated:YES];

is this possible?

this is in my AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    NSMutableArray *array = [[NSMutableArray alloc] init];

    MaktabatyTableViewController *own = [[MaktabatyTableViewController alloc] initWithStyle:UITableViewStylePlain];
    UINavigationController *ownNavController = [[UINavigationController alloc] initWithRootViewController:own];
    [array addObject:ownNavController];

    NewestTableViewController *newest = [[NewestTableViewController alloc] initWithStyle:UITableViewStylePlain];
    UINavigationController *newestNavController = [[UINavigationController alloc] initWithRootViewController:newest] ;
    [array addObject:newestNavController];

    MostBuyTableViewController *mostbuy = [[MostBuyTableViewController alloc] initWithStyle:UITableViewStylePlain];
    UINavigationController *mostbuyNavController = [[UINavigationController alloc] initWithRootViewController:mostbuy];
    [array addObject:mostbuyNavController];

    FreeBooksTableViewController *free = [[FreeBooksTableViewController alloc] initWithStyle:UITableViewStylePlain];
    UINavigationController *freeNavController = [[UINavigationController alloc] initWithRootViewController:free];
    [array addObject:freeNavController];

    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = array;

    [self.window setBackgroundColor:[UIColor whiteColor]];
    [self.window addSubview:self.tabBarController.view];

    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];

    return YES; 
}

Thanks in advance.

I think you are looking for something like this..

A login screen which is a simple view with login fields, upon login, this screen is of no use. And the main app is based on tab bar.

And a Logout screen or A screen showing after user signed out.

I had this requirement in one of my app, so i made a sample template. May be it helps you checkout this.
