> iAd has reportedly been underperforming since its release in 2010; The reason why I don't use iAd is because I can't. I wanted to put an ad banner across the top (or bottom) of my Landscape app at all times. My app used UISplitViewController which must be full-screen at all times and must be the root view controller. AdBannerView must be in a UIViewController and must be visible at all times. I have no problem with AdBannerView being visible at all times and UISplitViewController taking up the rest of the screen at all times. But the requirements conflict and to overcome them, I tried tons of different hacks but nothing was stable or guaranteed to work. I would have loved to use iAd in my iPad app but since it was not possible out of the box, I didn't bother trying to use it in production. What turned me away from iAd was not the difficulty in implementation but the realization that not ONE person at Apple thought "hmm, how does one put AdBannerView in an app that uses UISplitViewController?"
