如何让self.navigationController退出到指

HomeViewController:为你想要跳转的界面
HomeViewController *homeVC = [[HomeViewController alloc] init];

              UIViewController *target = nil;

              for (UIViewController * controller in self.navigationController.viewControllers) { //遍历

                  if ([controller isKindOfClass:[homeVC class]]) { //这里判断是否为你想要跳转的页面

                      target = controller;

                  }

              }

              if (target) {

                  [self.navigationController popToViewController:target animated:YES]; //跳转  

              }
