这样做:

NSArray *arrControllers = self.tabBarController.viewControllers;
for(UIViewController *viewController in arrControllers)
{
   if([viewController isKIndOfClass:[UINavigationController class]])
   {
     //NavigationController
     UINavigationController *navCtrl = (UINavigationController *)viewController;
     NSLog(@"%@",navCtrl.viewControllers);
   }
   else
   {
     // view controller
   }
}
