You will probably have to create your own module then (it's really not that difficult).
First, start off with the admob module and see how they integrated it. All they do is wrap the GADBannerView inside a TiUIView, then request an ad for each instance.
Then integrate this tutorial on BannerAds from millenial media. Essentially all you have to do is exchange GADBannerView
for MMAdView
and GADRequest for MMRequest
.
