How to merge video and recording and make single v

Question

I want to make video from images and merge the recording sound with this video.

After a lot of R&D and samples i am unable to merge both, till now i am only able to create video from images.

Can any one tell me the concept behind merging video and audio. I am using xcode 4.5 and iOS 6.

Thanks in advance.
