我该如何从viewController的死元素中获取

Question

I have this viewController I copied from a storyboard using Size Classes to another one that is not using Size Classes.

Before you say anything: there is a bug on XCode/iOS or whatever, that prevents a SplitViewController from being the rootViewController on iPads running iOS 7, unless you turn off size classes on xcode.

I have copied this viewController to the storyboard not using Size Classes and now all elements are grayed out.

How do I bring that to life?

It is not easy as you think.

Answer 1

This is just a guess, but what I would try is: Turn off size classes first in the original storyboard, and then copy.

(If you don't want to risk losing information from the original when you turn off size classes, make a duplicate of the original storyboard first.)

Answer 2

It's because the views have been set for a different size class in Interface Builder than the one which you have currently selected.

I encountered the same issue, read more here: Why don't my views show up in Storyboards and are greyed out in the left pane? and Interface Builder Objects not visible in my storyboard (and titles are transparent)
