Q:

customization of the camera overlay

My first question for customization is at here and with help from Mat. I can customize it. Now I would like to customize the overlay by loading and view from a nib file...
What I am to do is

Create another UIViewController called myCustomVIew with its xib
Add a toolbar on top and some buttons onto it
Set controller.cameraOverlay = aView.view

Please take a look at here, so that you can picture what I am doing so far

However when I run my app, the view is shown at here.
I know I have just screwed up somewhere, please advice me about this issue.

A:

You have to set a clearColor on the view, otherwise you can't see the camera layer.
