Question

我的UITabBarController的tabBar稍微偏离视图，请告诉我我的代码有什么问题：

LoggedInViewController *lvc = [[[LoggedInViewController alloc]
                               initWithAccount:account] autorelease];
[self presentModalViewController:lvc animated:YES];

- (void)viewDidLoad
{
    self.tabController = [[UITabBarController alloc] init];
    LoggedInFeedNavigationController *navController;
    navController = [[LoggedInFeedNavigationController alloc]
                     initWithAccount:self.account];
    [self.tabController setViewControllers:
        [NSArray arrayWithObject:navController]];
    [self.view addSubview:self.tabController.view];
    [super viewDidLoad];
}

您正在将tabController视图添加为子视图，但是您没有指定它应在父视图中的位置，或者在父视图更改大小时应如何调整它的大小。请尝试以下方法：

- (void)viewDidLoad
{
    [super viewDidLoad]; // see note

    self.tabController = [[UITabBarController alloc] init];
    LoggedInFeedNavigationController *navController;
    navController = [[LoggedInFeedNavigationController alloc]
                      initWithAccount:self.account];
    [self.tabController setViewControllers:
        [NSArray arrayWithObject:navController]];

    UIView *tabView = self.tabController.view;
    [self.view addSubview:tabView];

    tabView.frame = self.view.bounds;
    tabView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                                UIViewAutoresizingFlexibleHeight);
}

注意：您required不能[super viewDidLoad]拨打viewDidLoad，但如果您决定拨打电话，则应在beginning处致电{{1}}方法，而不是最终方法。

UITabBarController Tab Bar略微隐藏
