如何在 Interface Builder 中让 UIView 显示其导航控制器的导航栏
我有一个 UINavigationController，我在导航控制器下添加了一个 UIViewController。
基本功能运行良好，我可以单击视图控制器中的一个项目，它会将我带到第二个视图，并且我可以使用后退按钮返回。
我的问题是，当我在 IB 中时，当我编辑将位于 NavController 下的 VC 时，有没有办法告诉 VC“嘿，假装顶部有一个导航栏，这样我就可以考虑到导航栏来布置此视图”？当我打开将位于导航下方的 VC 的 xib 文件时，它会向我显示要编辑的完整视图，然后当它加载时，它会缩小并移动内容，一切都很好。但我可能想要一个以某种方式适合屏幕的特定视图，并且在构建将在导航控制器下使用的视图时，将标题栏放在顶部作为参考会很好。
I have a UINavigationController, I've added an a UIViewController under the nav controller.
The basic functionality is working fine, I'm able to click an item in my view controller and it takes me to a second view and I can use the back button to go back.
My question is, when I'm in IB, is there a way when I'm editing a VC that is going to be under a NavController to tell the VC "hey, pretend there is a nav bar at the top so that I can lay this view out with that nav bar in mind"? When I open up the xib file for the VC that is going to be under the Nav it shows me a full view to edit, and then when it gets loaded in it shrinks and shifts things and everything is good. But I may want a specific view that fits a certain way on the screen, and having the title bar up top would be nice as a reference when building a view that is going to be used under a nav controller.

在IB中选择主
UIView。在属性中，转到属性检查器。您将看到“模拟指标”。顶部栏有一个下拉菜单。将其设置为导航栏。Select the main
UIViewin IB. In the properties, go to the Attributes Inspector. You'll see "Simulated Metrics". There is a pulldown for Top Bar. Set it to Navigation Bar.
