I programmed an app such that when you press a button, it will call the iAd requestInterstitialAdPresentation()
function.
The first time I do this, it works normally. However, after I close the Ad view, and I press the button again, another ad will not appear. I even turned on the unlimited Ad presentation option in the developer settings in the iPhone.
Why does another ad not appear? Is there a time you need to wait to present the next ad?
