iphone - 如何将导航控制器添加到基于窗口的应用程序

Question

我有一个基于窗口的应用程序。我添加了两个视图控制器和一个Tabbarcontroller。现在我想将每个视图控制器导航到下一个视图。我试过但找不到解决方案。谁能帮帮我吗？

Answer 1

当您在窗口上添加标签栏时，添加如下 -

NSMutableArray * viewControllers = [[NSMutableArray alloc]init];


FirstViewController * firstViewController = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
UINavigationController * nvc = [[UINavigationController alloc] initWithRootViewController:firstViewController];
[firstViewController release];
[viewControllers addObject:nvc];
[nvc release];

SecondViewController * secondViewController = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
 nvc = [[UINavigationController alloc] initWithRootViewController:secondViewController];
[secondViewController release];
[viewControllers addObject:nvc];
[nvc release];

UITabBarController * tabBarController = [[UITabBarController alloc] init];
tabBarController.viewControllers = viewControllers;
[window addSubview:tabBarController.view];

编辑 - 每当您想在任何一个控制器中导航时。你只需要打电话

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

你会得到你想要的。:)

Answer 2

UINavigationController *urNavController = [[UINavigationController alloc] initWithRootViewController:rootController];

如果你想在窗口上显示这个

[window addSubview:urNavController.view];

Answer 3

像这样使用

secondViewController *obj=[[[secondViewController alloc] initWithNibName:@"secondViewController" bundle:nil] autorelease];
      UINavigationController *navBar=[[UINavigationController alloc] initWithRootViewController:obj];
      [self.navigationController pushViewController:navBar animated:YES];

      [navBar release];
