Set the title of Navigation Bar created in Interface Builder
提问by Steve
I have a modal view controller whose view comes from a XIB. I want it to have the same look and feel as the rest of my navigation based app, but it's not a view that's pushed to the navigation stack, it's presented modally. I dragged a UINavigationBar in and made it an outlet, but it doesn't have a title property to set. I have two fields that can bring up this modal view, and I want the title set differently depending on which one creates the modal view.
我有一个模式视图控制器，其视图来自 XIB。我希望它与我的基于导航的应用程序的其余部分具有相同的外观和感觉，但它不是推送到导航堆栈的视图，它以模态呈现。我拖了一个 UINavigationBar 并使它成为一个插座，但它没有要设置的 title 属性。我有两个字段可以调出这个模态视图，我希望根据哪个字段创建模态视图来设置不同的标题。

UINavigationBar's manage a stack of UINavigationItems much like a UINavigationControllermanager a stack of UIViewControllers. To set what is visible directly, you should use either pushNavigationItem:animated:or setItems:animated:using the navigationItem of the view controller you want the bar to reflect.
UINavigationBar管理一堆UINavigationItems 就像UINavigationController管理一堆UIViewControllers 一样。要设置直接可见的内容，您应该使用pushNavigationItem:animated:或setItems:animated:使用您希望栏反映的视图控制器的 navigationItem。
eg:
例如：
self.navigationItem.title = @"A custom title";
[self.navigationBar pushNavigationItem:self.navigationItem animated:NO];
The above code where you have a property navigationBarwhich references the stand-alone navigation bar.
上面的代码有一个navigationBar引用独立导航栏的属性。
If you don't want to manage it yourself, you can do as mplappert suggested and nest your view controller (without a stand-alone UINavigationBar) in a UINavigationControllerand present the navigation controller modally instead of your view controller.
如果您不想自己管理它，您可以按照 mplappert 的建议进行操作，并将您的视图控制器（没有独立的UINavigationBar）嵌套在 a 中，UINavigationController并以模态呈现导航控制器而不是您的视图控制器。

Also found this easier way if you've already defined a UINavigationBar in your IB. Assuming self.navigationBar is your IBOutlet:
如果您已经在 IB 中定义了 UINavigationBar，还可以找到这种更简单的方法。假设 self.navigationBar 是您的 IBOutlet：
self.navigationBar.topItem.title = title;

(Using XCode 4.5.2) Found a method that works directly in Interface Builder - without setting in code.
（使用 XCode 4.5.2）找到了一种直接在 Interface Builder 中工作的方法 - 无需在代码中进行设置。
With the ViewController object selected in (IB), under the Identity Inspector there is a section labeled "User Defined Runtime Attributes". I added the keyPath "title" of type String and set it to the value I wanted.
在 (IB) 中选择 ViewController 对象后，在 Identity Inspector 下有一个标记为“用户定义的运行时属性”的部分。我添加了 String 类型的 keyPath“标题”并将其设置为我想要的值。
Tested and this works when pushed onto a Nav Controller stack and when opened modally (with a Modal Nav Controller of course).
测试，这个作品时推到导航控制器堆栈，并且当模态打开（当然是一个模态导航控制器）。

Simply put your UIViewControllerinto a new UINavigationControllers view controller stack and present that navigation controller modally.
只需将您的视图控制器堆栈UIViewController放入一个新UINavigationController的视图控制器堆栈中，并以模态方式呈现该导航控制器。
