How to Set up the Raspberry Pi So it transmits Camera Feed through Wi-Fi to a iPhone?

I have been looking online to make a Raspberry Pi set up so that the camera feed is transmitted wirelessly through the USB Port which contains a usb g wireless. I wish then to be able to receive this feed through a iPhone, showing what the camera is transmitting by I have very little knowledge on how to program raspberry pi so the camera feed will be transmitted by the USB and received by the iPhone.

I suggest using Motion (sudo apt-get install motion), which lets you stream images to a web server port. You could then have a page with:

<img src="//localhost:8080">

on it, and then use iPhone to go to http://yourpi/camera.html and look at that page.
Here is a good link to an installation guide:

You will probably only need the instructions after the bit about Motion starts, but it may be helpful to read it all!

Hope this helps, and good luck!
