title: Ad in integration in iOS application
body: <p>I have one iOS universal application with more that 2 lacs users on iTunes. Currently application is free on iTunes. Now, I am thinking to add Ad integration in my application. I have some confusion for which platform I forward. Do I need to integrate iAD OR AdMob OR any other platform ? Is there any chart available which shows how much money I can earn with 2 lacs users ?</p>
