I also use AdMob and have always been pretty happy with them but I keep hearing about how much better the iAds are paying out. The one big drawback to iAds being you don’t get as many ads as you would with AdMob. I understand there are some advertising networks out there that allow you to take advantage of multiple ad networks. The problem there is that you are under their control and who knows how and when they regulate those ads. So why not take control yourself?

So I began searching for a method of integrating both myself. Fortunately I found a post on the xcode noobies blog. They had a blog post outlining something very similar to what I was looking to accomplish. Their code was designed to display an iAd unless the app was being run on a device running iOS 3.2 which doesn’t support iAds. So instead of loosing revenue on older devices their intent was to load AdMob Ads as backup. So, I modified their code to load AdMob Ads as a fallback whenever an iAd is not available – rather than just when the OS version was too old to support iAds. I think this is ultimately more useful. The OS detection code is still present but not very necessary. Just make sure if you are  targeting iOS 3.2 or below to WEAK LINK the iAd Framework.

UPDATE: 9/29/11: After experimenting with the project below for some time I have found it to be quite troublesome and buggy. I am leaving the code up as it may be a good starting point for someone but use at your own risk!

Code calls 1st for the iAd and 2nd for the AdMob Ad – If an iAd is available it’s displayed right away. If not,  hopefully an AdMob ad is displayed. Even when AdMob ads are being displayed the app checks for iAds (refresh time is controlled by Apple) and loads them as soon as they are available.  AdMob Ads are refreshed every 30 seconds in code (you can adjust this.) Hopefully with this we can all maximize our income =) The project can be downloaded HERE.

Now I have to warn you. I have no idea if this method of doing things is 100% correct. I’m not an expert. This project uses a 9 month old version of the AdMob SDK. I have tried unsuccessfully to update the code to run with the latest Google/AdMob SDK.  I was able to update the code to utilize the latest Google/AdMob SDK version 4.1.1 =) Enjoy!
