多行UINavigationBar(Multi-line UINavigationBar)

对于模态对话，我希望有一个UINavigationBar，其中包含一个较小的任务描述，然后是传统的UINavigationBar - 这是iOS上许多系统应用程序中看到的样式。

实现这一目标的最佳方法是什么？

要查看我的意思，请参阅地图和联系人的这些示例屏幕截图（我选择iOS6屏幕截图，因为标准渐变扩展也是我想要的）。

For a modal dialogue, i would like to have a UINavigationBar with a smaller description of the task, followed by a traditional UINavigationBar - this is the style seen in many of the system apps on iOS.

What is the best way to achieve this?

To see what I mean, see these example screenshots from Maps and Contacts (I choose the iOS6 screenshots, because having the standard gradient expand is also something which I would like to have).

您发布的屏幕截图使用的是UINavigationItem prompt属性。

在视图控制器中，您可以执行以下操作：

- (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.prompt = @"Some message to appear at the top"; self.title = @"Some Title"; }

The screen shots you posted are using the UINavigationItem prompt property.

In your view controller you can do this:

- (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.prompt = @"Some message to appear at the top"; self.title = @"Some Title"; }
