Beginning using AdMob
in an iOS app, I have this question:
When I am testing my app, I should not be using real adds. For that I use:
bannerUnitID = "ca-app-pub-3940256099942544/2934735716" // Provided in Google’s tutorial.
All is fine with that. But I read I can also add my device for test using this:
// Requests test ads on test devices.
request.testDevices = ["2077ef9a63d2b398840261c8221a0c9b"] // Using the proper code for my device obviously.
What is the difference between using the first way and the second way?
I tried and could see that with the second way, I seem to be getting real adds. It is not clear to me, what is going on here. Anyone with a clear view? Please explain.
