Select second tab from ModalViewController

Question

In my app delegate I load a view controller on top of my tabbar. This controller had three buttons on it, one to navigate to each tab. When the second button is pressed, I want to dismiss the view controller and go to the second tab. But this doesn't seem to work the normal way.

My AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{    
    //-- Insert a delay of 5 seconds before the splash screen disappears
    [NSThread sleepForTimeInterval:3.0];        

    // Set the tab bar controller as the window's root view controller and display.
    self.window.rootViewController = self.tabBarController;

    // Set StartView to load first
    StartViewController *startViewController = [[StartViewController alloc] initWithNibName:@"StartView" bundle: nil];
    [window addSubview: [startViewController view]];
    [window makeKeyAndVisible];

    [self.tabBarController presentModalViewController:startViewController animated:NO];
    [startViewController release];

    return YES;
}

And here is my current IBAction, which doesn't seem to work:

 - (IBAction) toSecondView:(id)sender
    {
    // Show status bar
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];

    [(UITabBarController *)self.parentViewController setSelectedIndex:1];

    [self dismissModalViewControllerAnimated:NO];
}

I tried these too, without success:

self.tabBarController.selectedIndex = 1;

and

[self.tabBarController setSelectedIndex:1];

Can anyone help me out and explain me what I'm missing?

it's happend because of ,you have added viewcontroller onto the window as subView and then presenting that viewController on tabBarController — Kamar Shad, Feb 27 '12 at 11:03

This happend because a below of reason.

You have added ViewController Onto the Window As a subView, no need to add SubView because you are already presenting that ViewController as ModalViewController.

Please Try as below.

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    
//-- Insert a delay of 5 seconds before the splash screen disappears
[NSThread sleepForTimeInterval:3.0];        

// Set the tab bar controller as the window's root view controller and display.
self.window.rootViewController = self.tabBarController;

// Set StartView to load first
StartViewController *startViewController = [[StartViewController alloc] initWithNibName:@"StartView" bundle: nil];
//[window addSubview: [startViewController view]]; no need to add subView here
[window makeKeyAndVisible];

[self.tabBarController presentModalViewController:startViewController animated:NO];
[startViewController release];
return YES;

}

-(IBAction) toSecondView:(id)sender
{
// Show status bar
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
//create delegate's class object for accessing tabBarController
 AppDelegate* delegate=(AppDelegate*)[[UIApplication sharedApplication]delegate];
 //instead of [(UITabBarController *)self.parentViewController setSelectedIndex:1];
 //delegate.tabBarController your tabBarControler at which you have added viewController
[delegate.tabBarController setSelectedIndex:1];

[self dismissModalViewControllerAnimated:NO];

}
