如何从MainStoryboard为UIViewController分配标识符? [英] How to assign an identifier to a UIViewController from the MainStoryboard?

问题描述

在我以前使用initWithNibName分配和初始化视图控制器之前，其中Nib名称的参数只是xib/nib文件的名称.

Before I used to allocate and initialize a view controller using initWithNibName, where the parameter for the Nib name is simply the name of the xib/nib file.

但是，现在Xcode/IB与Storyboard一起使用的方式，我不确定用各自的xib/nib初始化视图控制器类需要做什么.

However, with the way Xcode/IB works with Storyboards now, I'm not sure what I need to do to initialize a view controller class with it's respective xib/nib.

在我的情节提要中，我创建了一个视图控制器，并从另一个视图控制器中引用了它，并将其指定为Popover类型.

In my storyboard i have created the view controller and referenced it (from another view controller) and specified it as a Popover type.

有什么想法可以实现吗?

Any ideas how this is accomplished?

谢谢.

Apple文档说

要在情节提要中标识特定的视图控制器或设置， 使用Interface Builder为它分配一个唯一的标识符字符串 识别它.

To identify a specific view controller or segue inside a storyboard, use Interface Builder to assign it an identifier string that uniquely identifies it.

但是我不知道如何通过IB分配唯一的ID.该怎么做?

But I can't figure out how to assign a unique id via IB. How to do this?

推荐答案

XCode 4.4 and earlier: Identifier; 
XCode 4.5: Storyboard ID
