How to add video to a tab bar controller in Xcode 4.2?


I am fairly new to Iphone programming and I want to know how to write coding which allows you to click a button labelled ‘Play Video’, on a tab bar controller, which leads to a video player, which automatically plays a chosen video and has the capabilities to pause, fast forward, rewind and has volume control.

If anyone can assist me on this it would be greatly appreciated.
