Try:

 NSArray *mycontrollers = self.tabBarController.viewControllers;
 NSLog(@"%@",mycontrollers);
 UINavigationController *nvc = [mycontrollers objectAtIndex:0];
 UIViewController *vc = [nvc topViewController];
 [self.navigationController popToViewController:vc animated:YES];

Control-drag form your button to you new viewcontroller and select Modal.
