iAd
iAd is the Apple advertising platform. It comes with the intent of developing the
freemium model. What is the freemium model? Basically it's one in which you
can develop an application/game that is free to users but that displays ads
within the game spaceto generate revenue from advertising or iAP (in-app
purchase).
iAd provides you with a complete framework to display either banner or full-
screen ads in your application; these come directly from Apple. Thus you don't
need to bother about selling the ad space. You just need to design the area for
the ad space and then the iAd framework will manage it from there.
To use iAd in your GameSalad project, you must join the iAd network. In
iTunesConnect, the first step is to setup your contract with Apple.
iAd was introduced with iOS 4. This means that all pre-iOS 4 will not be
compatible with iAd. The iAd feature is only accessible to Pro members.
