I am implementing ad-whirl in my iOS project. I need advertisement in my app by 3 networks, Admob, Millennial Media and iAd. I already activated those 3 networks on my ad-whirl account and I downloaded the example SDK for Adwhirl. But the Adnetworkslib folder is empty - how can I add those networks lib to my project?
You need to download those SDK's separately, they do not come packaged with AdWhirl. You can download Millennial from here, and AdMob from here.
I believe iAd is just a linked framework that you add to your project in XCode.
