How to create new View Controllers in XCode 4.3
提问by user1007895
So I have figured out that in XCode 4.3, to create a new ViewController, I have to do New > Objective-C Class, then subclass UIViewController. But, how come the xib checkbox is greyed out? How do I create a new view controller with an xib?
所以我发现在 XCode 4.3 中，要创建一个新的 ViewController，我必须执行 New > Objective-C Class，然后子类化 UIViewController。但是，为什么 xib 复选框是灰色的？如何使用 xib 创建新的视图控制器？

I have no idea why the xib box is grayed out (doesn't happen for me), but you can always just go to new file and create a nib from there and set its class to your UIViewControllersubclass in interface builder.
我不知道为什么 xib 框变灰（对我来说不会发生），但是您始终可以转到新文件并从那里创建一个笔尖并将其类设置为您UIViewController在界面构建器中的子类。

This is a bug, just select the UIViewController again in the Subclass ofcombo and it will be enabled again.
这是一个bug，只需在combo的Subclass中再次选择UIViewController ，它就会再次启用。
Happened to me when i canceled the creation once and opened the dialog again.
当我取消一次创建并再次打开对话框时发生在我身上。
