Swift Storyboard Auto Size Classes

Question

i have a problem. I had a storyboard in Xcode 6 with the inferred size of the view controller and the "Use Auto layout" option checked. Today i wanted to use the new " Use Size Classes" option. I checked the option and then in the simulator the screen was all black!

EDIT

now that i resolved this issue i have another thing here ! I use "Add missing costraints" option to have a resize for all Apple Device, the Tab bar and navigation bar are good, but then all the buttons ( they have an image ) are in different position !

How i can resolve that ? Thanks in advance.

Answer 1

You should avoid as possible the use of "add missing constrains". Is an automatic tool that almost always ends up adding unnecessary constrains or breaking others.

If you want something to look really good an stable, sadly there are no shortcuts... you will eventually end having to do it all by yourself.

Answer 2

A black view.. if not always, is a good indicative that the view is not loaded. Size Classes introduces a new concept ...You can have several views that will be installed or not into your view depending of your view configuration. More details on images below:

This is what you will be looking for:

This is what I call view rendering configuration (sure Apple has another name for it). It is located at center bottom of your storyboard view.

This is always located at the end of Attributes Inspector tab:

Make sure it is enabled for the view that suits your testing device.

Answer 3

I found out that the ViewController wasn't set as Initial Controller.
