Following is my code

Answer 1

For me (what I see in your code), your are not adding the parentlayer to the screen.

You create a CALayer() to add videolayer, imglayer and titleLayer into a new layer but you don't add this last one on the screen.

yourView.layer.addSublayer(parentlayer)

Hope this help you
