标题未出现在 TabBarItem 中，但图像出现

我添加了一个选项卡栏控制器，并尝试向该项目添加标题和图像，但仅显示图像。标题根本就看不到。任何建议将不胜感激。

_tabbarController = [[UITabBarController alloc] init];
_showsController = [[showsController alloc] init];
_showsController.title = @"Test1";
_showsController.tabBarItem.image = [UIImage imageNamed:@"Glass.png"];
[_tabbarController setViewControllers: [NSArray arrayWithObjects: _showsController, nil]];

更新：在stackoverflow上搜索了一段时间，终于找到了解决办法，添加如下代码： *self.view = _tabbarController.view;*

我很抱歉没有提供更多信息（这不是 rootViewController，而是作为子视图添加的），并感谢您的帮助。

I've added a tab bar controller and am trying to add a title and image to the item, but only the image shows. The title is nowhere to be seen. Any suggestions would be greatly appreciated.

_tabbarController = [[UITabBarController alloc] init];
_showsController = [[showsController alloc] init];
_showsController.title = @"Test1";
_showsController.tabBarItem.image = [UIImage imageNamed:@"Glass.png"];
[_tabbarController setViewControllers: [NSArray arrayWithObjects: _showsController, nil]];

UPDATE:
After searching stackoverflow for a while, I finally found the solution by adding the following code:
*self.view = _tabbarController.view;*

I apologize for not giving more information (that this was not the rootViewController but added as a subview instead), and thank you for your help.

您需要设置 UITabBarItem 标题：

 _showsController.tabBarItem.title = @"Test1";

或者一次性设置它们：

_showsController.title = _showsController.tabBarItem.title = @"Test1";

You need to set the UITabBarItem title:

 _showsController.tabBarItem.title = @"Test1";

Or set them both in one go:

_showsController.title = _showsController.tabBarItem.title = @"Test1";

您还需要在 UITabBarItem 对象上设置标题。

_showsController.tabBarItem.title = _showsController.title;

就我个人而言，我更喜欢让 UIViewController 子类在可能的情况下处理自己的标题。这使您的代码更加独立，并且并不总是强制 UIViewController 的创建者正确初始化它。

例如，在您的 UIViewController 子类中：

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]))
    {
        UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"Test1"
                                                           image:[UIImage imageNamed:@"Glass.png"]
                                                             tag:1];
        [self setTabBarItem:item];
        [item release];
    }

    return self;
}

You also need to set the title on the UITabBarItem object.

_showsController.tabBarItem.title = _showsController.title;

Personally, I prefer to let the UIViewController subclass handle its own titles when possible. This makes your code more self-contained and doesn't always force the UIViewController's creator to initialize it properly.

For example, in your UIViewController subclass:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]))
    {
        UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"Test1"
                                                           image:[UIImage imageNamed:@"Glass.png"]
                                                             tag:1];
        [self setTabBarItem:item];
        [item release];
    }

    return self;
}
