Clean way to force view to load subviews early

Question

Recently I wrote some code where I tried to refer to an outlet on a UIViewController I\'d just instantiated with [storyboard instantiateViewControllerWith

Answer 1

I agree that forcing a view to load should be avoided but I ran into a case where it seemed the only reasonable solution to a problem (popping a UINavigationController containing a UISearchController that had yet to be invoked causes a nasty console says warning).

What I did was use new iOS9 API loadViewIfNeeded and for pre-iOS9 used viewController.view.alpha = 1.0. Of course a good comment above this code will prevent you (or someone else) removing this code later thinking it is unneeded.

The fact that Apple is now providing this API signals it can be needed from time to time.
