How to use size classes and autolayout in storyboard?

I am trying to use size classes and Autolayout in storyboard.

//So sorry that I cant post images for not enough reputaitons.

It seems that I've uploaded my photo successfully, and it is here now. The white area is the UIView, and only a UILable as its subview, the size class is wCompact and hRegular.

I set a UIView below the UINavigationBar, and then add a UILabel on the view. To show this on the all the iphone simulator, I user the wCompact and hRegular size classes.

I want the label to be set in the center of the screen. So I set a constrains for the label that Align horizontal center in container.

But I can't see anything on the simulator, even the UIView disappears.

Does anyone know what happened?

OK, I've found such a stupid mistake. I have't set the contrains for the UIView, so it's covered by the navigationBar...this will not happen on Xcode5, for the View is just below the UINavigationBar in the storyboard.

I tried log the UIView's frame, but I did that in the viewdidLoad method, then I got a wrong frame, because the UIView instance in the storyboard hasn't be init at that time...I should do that in the viewDidAppear method...

Tks for your answers.

Maybe the height of your UIView changes? Try putting constraints to your UIView too.
