Question

主屏幕后没有显示标题。我在第一个屏幕后放了UITabBarController。第一个屏幕没有UITabBarController。我不确定我实施标签的方式。

我已在self.title = @"title"的每个视图控制器中设置了标题。标题正确地显示在标签项中。

AppDelegate.m：

 UIViewController *loginView= [[[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil] autorelease];

UINavigationController *loginViewNavController = [[UINavigationController alloc] initWithRootViewController:loginView ];

self.navigationController = loginViewNavController;

self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];

LoginViewController.m：

-(IBAction)navigateMainMenu:(id)sender{

tabBarController = [[UITabBarController alloc] init];

MyAccountsViewController *vc1 = [[MyAccountsViewController alloc] initWithNibName:@"MyAccountsViewController" bundle:nil];
DepositsViewController *vc2 = [[DepositsViewController alloc] initWithNibName:@"DepositsViewController" bundle:nil];
MoreViewController *vc3 = [[MoreViewController alloc] initWithNibName:@"MoreViewController" bundle:nil];
PayTransViewController *vc4 = [[PayTransViewController alloc]init];

NSArray* controllers = [NSArray arrayWithObjects:vc1,vc4, vc2, vc3, nil];
tabBarController.viewControllers = controllers;

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

[mainMenuViewController release];

Answer 1

主要以吼叫的方式显示标题： -

1. Self.title=@"Your Titile";

2. self.navigationItem.title=@"your Title";

3. when you using UItabBarController you can set Particular Viewcontroller as par your code Title like:- 

  vc1.title=@"your Title";
  vc2.title=@"your Title";
  vc3.title=@"your Title";
  vc4.title=@"your Title";

Answer 2

如果你设置self.title = @“Title”。该标题将在navController标题中设置。但是在你的TabBarController中，每个项目都是ViewController。不是navigationController。

问题：您在此行[mainMenuViewController release];

Answer 3

我建议你不要在navigationcontroller中使用tabbarcontroller。如果您使用tabbarcontroller，它应该是rootViewcontroller。

标题没有显示在导航栏iphone应用程序中
