new GUI doesn't show up in iPhone 5s.

I’ve created a button in unity 4.6 beta. Then I transferred it to iphone 5s. Button didn’t show up. Bu it seems button is there. When I tap on screen where button is supposed to show up button event code was working.
What did I do wrong? Any ideas?

I built and run in iPhone by following order.

  1. File->Build Settings-> Selected iOS as Platform → Added scene to build → pressed “Build and run” button.

Does it need to have pro license to show a new GUIs in iPhone?

AAhh, I didn’t attach camera to property “Render Camera” of canvas.
