popToViewController的用法(跳转到你想跳转到的那个控制器)

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

或

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