UITabbar 应用程序中的方向问题

Question

我正在开发标签栏应用程序，其中我按以下方式调用导航控制器 问题是我无法定向到横向模式。谁能告诉我我做错了什么吗？

问候， 萨蒂什

-(IBAction)click


{

    tabBarController = [[UITabBarController alloc] init];

    NSMutableArray *localControllersArray = [[NSMutableArray alloc] initWithCapacity:5];

    UINavigationController *localNavigationContriller;

    FavouritesViewController *master;
    master = [[FavouritesViewController alloc] initWithTabBar];
    localNavigationContriller=[[UINavigationController alloc] initWithRootViewController:master];
    [localNavigationContriller.navigationBar setBarStyle:UIBarStyleBlackTranslucent];
     [localControllersArray addObject:localNavigationContriller];
    //[localNavigationContriller release];
    [master release];

    NeedViewController *need;
    need = [[NeedViewController alloc] initWithTabBar];
    localNavigationContriller=[[UINavigationController alloc] initWithRootViewController:need];
    [localNavigationContriller.navigationBar setBarStyle:UIBarStyleBlackTranslucent];
    [localControllersArray addObject:localNavigationContriller];
    //[localNavigationContriller release];
    [need release];

    DontNeedViewController *dontneed;
    dontneed = [[DontNeedViewController alloc] initWithTabBar];
    localNavigationContriller=[[UINavigationController alloc] initWithRootViewController:dontneed];
    [localNavigationContriller.navigationBar setBarStyle:UIBarStyleBlackTranslucent];
    [localControllersArray addObject:localNavigationContriller];
    //[localNavigationContriller release];
    [dontneed release];

    tabBarController.delegate=self;
    tabBarController.viewControllers = localControllersArray;
    [localControllersArray release];

    [[[UIApplication sharedApplication] keyWindow] addSubview:tabBarController.view];
}

听着，伙计，你必须在所有选项卡栏中将 shouldrotate 函数重写为 YES，就像你的应用程序中有 3 个选项卡栏一样，转到相应的类以及

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    // Return YES for supported orientations.

    return YES;
}

选项卡栏的所有相应类中...希望有所帮助，如果它确实为我祈祷......

Answer 2

不可能更改 tabBar 中一个视图的方向而不更改另一个视图的方向。如果指定了 TabBar，则所有子视图（选项卡）必须具有相同的方向外观。您必须在每个 ViewController 和 TabBarController 中设置方向。

因此，只需将其添加到所有选项卡栏的主控制器中，

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
        return YES;

    return toInterfaceOrientation != UIInterfaceOrientationPortraitUpsideDown;
}

在您的情况下，要添加此代码的控制器是
FavoritesViewController，
NeedViewController &
DontNeedViewController
