除了 titleView 之外，还向 UINavigationBar 添加标签

我正在使用 UINavigationController 来推送我的视图。我想在根视图控制器的 UINavigationBar 中的标题上方添加一个 UILabel。

当我使用以下代码时，标签会出现，但位于 UINavigationBar 下方：

[self.view addSubview:newLabel];

有没有办法将标签添加到 UINavigationBar 或 UIView 中，以便它显示在导航栏上方？

我知道我可以创建一个新的 UINavigationBar 并使用多个控件构建它，如下所示：

UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
navBar.barStyle = UIBarStyleBlack; 
navBar.translucent = YES;
[self.view addSubview:navBar];
[navBar release];

UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(20,8,280,30)];
navLabel.text = @"My Text";
[navBar addSubview:navLabel];
[navLabel release];

但是，这是否违背了使用导航控制器的目的？

I'm using a UINavigationController to push my views. I want to add a UILabel above the title in the UINavigationBar of the root view controller.

When I use the following code, the label appears, but under the UINavigationBar:

[self.view addSubview:newLabel];

Is there a way to add the label to the UINavigationBar or to the UIView so that it appears above the navigation bar?

I know I can create a new UINavigationBar and build it with multiple controls like this:

UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
navBar.barStyle = UIBarStyleBlack; 
navBar.translucent = YES;
[self.view addSubview:navBar];
[navBar release];

UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(20,8,280,30)];
navLabel.text = @"My Text";
[navBar addSubview:navLabel];
[navLabel release];

However, doesn't that defeat the purpose of using the navigation controller?
