Adwhirl advertisement fetching from Admob

I integrated Ad开发者_Python百科whirl into my IOS app, opened an account and included the sdk of Admob to my project. I have set up all the things that I had to. The problem is when I run my application I don't see any ads displaying on my screen. However, in adMob site, my requests are increasing whenever I request from my phone. How can I display my ad on the screen?

P.S: When I run adwhirl in test mode it works fine.
