使用UINavigationBar而不使用UINavigationController [英] using UINavigationBar without UINavigationController

问题描述

我想在我的UIWebView顶部使用UINavigationBar，但我想手动控制标题，后退按钮，后退按钮的功能 - 等等。换句话说，我从不想推送或弹出视图。我只想在用户点击Web视图时更改UINavigationBar内容。

I want a UINavigationBar at the top of my UIWebView but I want to control by hand the title, the back button, what the back button does - etc. In other words I never want to push or pop views. I just want to change the UINavigationBar contents as the user clicks around the web view.

我在那里将UINavigationBar添加到我的superView并使其高44像素。由于我没有navigationItem，如何设置标题？我该怎么设置一个假的后退按钮？

Where I'm up to is I added the UINavigationBar to my superView and made it 44 pixels tall. How do I set the title since I have no navigationItem? How would I set a fake back button up?

我很感激任何指针。我意识到这很奇怪我正在做什么。

I would appreciate any pointers. I realise this is quite weird what I'm doing.

谢谢：）

推荐答案

如果有兴趣的话，答案就在UINavigationBar的类引用中。

The answer, if anyone's interested, is in the class reference of UINavigationBar.

当你使用导航栏作为独立对象，你是
负责提供其内容。 与其他类型的观看不同，
您不直接将子视图添加到导航栏。相反，您使用
导航项（UINavigationItem类的实例）到
指定要显示的按钮或自定义视图。导航
项目具有用于指定导航栏左侧，右侧和
中心的视图以及用于指定自定义提示
字符串的属性。

When you use a navigation bar as a standalone object, you are responsible for providing its contents. Unlike other types of views, you do not add subviews to a navigation bar directly. Instead, you use a navigation item (an instance of the UINavigationItem class) to specify what buttons or custom views you want displayed. A navigation item has properties for specifying views on the left, right, and center of the navigation bar and for specifying a custom prompt string.

简而言之，使用UINavigationItem并在UINavigationBar上通过pushNavigationItem应用它。

In short, use a UINavigationItem and apply it by "pushNavigationItem" on the UINavigationBar.

我创建了一个子类UINavigationBar调用StaticNavigationBar，然后我可以通过在其上放置适当的UINavigationItem来加载任何状态。感谢您的所有答案。

I created a subclass of UINavigationBar called StaticNavigationBar which I can then load with any state by putting the appropriate UINavigationItem's on it. Thanks for all your answers people.
