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.
