How to I connect Button Action to Tabbar Viewcontrollers

Question

I am new to iPhone development. I am developing a TabBarViewcontroller App (iPhone and iPad) and in that I've created one LoginViewController and a Button Action. My expectation is after clicking that Button, the control will move from LoginViewController to TabBarViewController. In this TabBarViewcontroller I have 5 Tabbar (items) ViewControllers. Is it possible?

If you can, please share your ideas.

Answer 1

First of all, take UINavigationController and UITabbarController in your MainWindow.xib and bind IBOutlet to respective fields.. ans set LoginViewController as rootViewController of your UINavigationController..

Then in didFinishLaunchingWithOptions method write this..

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{
    [self.window setRootViewController:navController];
    [self.window makeKeyAndVisible];    
    return YES;
}

Now create other method in AppDelegate.m like this..

-(void)loadApplication
{
    [navController pushViewController:tabbarController animated:NO];
}

On your Login button action.. call this method as follows..

-(IBAction)btnLoginTapped:(id)sender
{
    AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];
    [appDelegate loadApplication];
}

Answer 2

So in button action try following codes

AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; 
appDelegate.window.rootViewController = tabBarController;
