Example for login screen modally based on storyboard

Here is scenario . Its so simple . I just hope that it will be useful.

For the UITableBarController give a name for identity to storyboard id

Then in your ViewController class file You have the authentication credentials right >.? Do some stuff over there for authentication . then follow this code . It works fine

- (IBAction)Login:(id)sender {

    if(authenticated)  // authenticated---> BOOL Value assign True only if Login Success
        {
            UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
            UITabBarController *obj=[storyboard instantiateViewControllerWithIdentifier:@"tab"];
            self.navigationController.navigationBarHidden=YES;
            [self.navigationController pushViewController:obj animated:YES];
        }
