[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:2] 
      animated:YES];

或

 　　for (UIViewController *temp inself.navigationController.viewControllers) {
           if ([temp isKindOfClass:[你要跳转到的Controller class]]) {
              [self.navigationControllerpopToViewController:temp animated:YES];
           }
       }
