I am getting this warning from Google (adMob) that the SDK needs to be updated to support iOS8.
\<Google:HTML\> You are currently using version 6.8.0 of the SDK, which doesn't officially support iOS 8. Please consider updating your SDK to the most recent sdk version, 6.12.0, to get iOS 8 support, including a fix for smart banner rendering in landscape mode. The latest SDK can be downloaded from http://goo.gl/iGzfsP. A full list of release notes is available at https://developers.google.com/mobile-ads-sdk/docs/admob/ios/rel-notes.
