In my project I have a splitview and had previously implemented iAds using the splitview example from the Apple iAdSuite. Now I also wanted to implement Admob ads and since Adwhirl gave many errors in xcode 4.5 I tried using Admob Mediation (iOS SDK 6.2.0).

I got the ads to load and it properly mediates between iAd and Admob when necessary. However, one big problem remains. When I rotate the device (or simulator) before any ads have been loaded, I get the following crash:

Terminating app due to uncaught exception ‘NSRangeException’, reason: ‘* -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array’

* First throw call stack:

libc++abi.dylib: terminate called throwing an exception

As a test I implemented Admob Mediation also in the iAdSuite splitview example (
can be found here) and see the same crash. Once an ad is loaded you can rotate all you want without any crashing. When I use Admob only (no mediation) I cannot make this crash happen.

It seems like it is crashing in the Admob code but there might be something else I’m not doing right to cause this. But at this point I’m stuck. Does anybody have an idea of how to make this crash go away?

Edit:
I got the “Smart Banner Example 1.2” that Admob provides at http://code.google.com/p/google-mobile-dev/downloads/list. The only thing I ‘changed’ was to add the actual Admob SDK 6.2.0 files, the iAdAdapter, add the iAd framework and use a mediation ID. This also crashes on rotation when no ads are loaded yet.

I tried to post this issue on the Google AdMob Ads Developers forum but briefly something flashes up saying something like that the post needs to be approved. After two days nobody seems to have looked at the approval queue yet.

    Looks like this might be an issue with the AdMob SDK. I would probably workaround it by setting a boolean (i.e firstAdReceived) when you get an ad the first time, and then checking that before you change the adSize and other banner characteristics on orientation change.
