If you've not already got an application but would still like to try adding iAd into an app, we can make a quick single-screen placeholder iPhone project that'll be ready to have a banner added to it.
Note
We'll be using Xcode; we installed this in Chapter 4, Making Sure it Works, when we set up the iOS Simulator, so you should have it available (if not, then jump back and set it up now).
If you don't want to set up the demo app, you can find the completed placeholder project with the book assets in the iAd Demo App
folder.
