There currently isn't an easy way to record the output of our iOS device, so we'll use the iOS Simulator and QuickTime to record our iAd.
1. Open your ad in the iOS Simulator, making sure your ad isn't fully open, so that just the banner is visible.
2. Now open QuickTime Player from the
Applications
folder. Choose File, then New Screen Recording, from the menu bar.3. QuickTime will now show you a window with a red recording button in it. When you want to start recording, click this button. The Start Recording window with its instructional dialogue is shown in the following screenshot:
4. Before recording, QuickTime will show you instructions on how to stop the video; you can either use the Stop Recording item in the menu bar or the keyboard shortcut Cmd + Ctrl + Esc.
5. Click Start Recording and start interacting with your iAd. Once you've got the footage you wanted, stop the recording.
