Answer 1

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.


    if(!isAgreementAccepted)
    {

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"IDD"];
    self.window.rootViewController=vc;
    }

    return YES;
}

If agreement is not accepted set the T&C viewController as rootViewController when user click the accept button then set the TabBarviewController as root.

u can access the widow object through application delegate any where

[[[UIApplication sharedApplication]delegate] window].rootViewController=tabViewController.

Answer 2

If Tabbarcontroller is your root viewcontroller, then using below code will resolve the issue in your appdelegate.

 -(void)showCountrySettings
  {

     if (self.termsHaveBeenAccepted){

    BBCounterySettingsViewController *countrySettings = [[BBCounterySettingsViewController alloc]initWithNibName:@"View" bundle:nil];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"IDENTIFIER"];
    UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;

    [tabBarController presentModalviewcontroller:vc animated:YES completionblock:nil];
  }

Answer 3

Change the rootviewcontroller of window programaticaly

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

   UIStoryboard *aStoryBoard=[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
   UITabBarController *aTabCtrl=[aStoryBoard instantiateViewControllerWithIdentifier:@"Tab"];
   FirstVC *aFirstCtrl=[aStoryBoard instantiateViewControllerWithIdentifier:@"First"];

   if(self.termsHaveBeenAccepted)
      self.window.rootViewController=aFirstCtrl;
   else
      self.window.rootViewController=aTabCtrl;
   return YES;
}

This will definitely work I have tested.
