导航控制器到选项卡栏控制器

Question

我正在对我的应用进行情节提要。 该应用程序的结构是不带导航栏或标签栏的登录屏幕，该登录屏幕通向应用程序，并在所有屏幕上显示导航栏和标签栏。 因此，导航控制器通向标签栏控制器。

登录成功后，我尝试了以下方法：

UITabBarController *tabBarController=[[UITabBarController alloc]init];

DiaryViewController *diaryViewController = (DiaryViewController *)[storyboard instantiateViewControllerWithIdentifier:@"diary"];
WhosOutViewController *WOutViewController = (WhosOutViewController *)[storyboard instantiateViewControllerWithIdentifier:@"WhoOut"];
WhatsNearViewController *whatsNearViewController = (WhatsNearViewController *)[storyboard instantiateViewControllerWithIdentifier:@"WhatsNear"];
MoreViewController *moreViewController = (MoreViewController *)[storyboard instantiateViewControllerWithIdentifier:@"More"];
tabBarController.viewControllers=[NSArray arrayWithObjects:diaryViewController,whatsNearViewController, WOutViewController, moreViewController, nil];

[self.navigationController pushViewController:tabBarController animated:YES];

它确实会推送并显示一个标签栏，但不会显示导航栏。 有人可以帮我吗？ 或者，请提出另一种实现此方法的方法。

提前致谢

建议 。您应该反过来做：

self.navigationControllerOne.viewControllers = [NSArray arrayWithObject:diaryViewController];
self.navigationControllerTwo.viewControllers = [NSArray arrayWithObject:whatsNearViewController];
...
tabBarController.viewControllers=[NSArray arrayWithObjects:self.navigationControllerOne ,self.navigationControllerTwo, ... , nil];

然后愉快地推动/关闭
