Today, we released v6.2 of the AdMob SDK for iOS developers. This release includes a number of bug fixes as well as some important changes for iOS 6 and the iPhone 5. This post will go through some important differences developers should keep in mind when working with AdMob v6.2. All of our developer docs have already been updated to reflect these change.

XCode 4.5 and iOS 6

We’ve made a number of changes to add support for both iOS 6 and the iPhone 5. This means that you will need to use XCode 4.5 and build against iOS 6 when using our SDK. You can still support down to iOS 4.3 by setting your “Deployment Target” to iOS 4.3 in your project’s Application Target.

Support for armv7s

The iPhone 5 is powered by the A6 processor which uses the armv7s architecture, so targeting armv7s will optimize your app to run on iPhone 5. We’ve dropped support for the armv6 architecture and added support for the armv7s architecture in this release (we also still support armv7). New projects created via XCode 4.5 default to supporting armv7 and armv7s, meaning that this shouldn’t be an issue as long as you’re using the correct version of XCode.

If you’re targeting the armv7s architecture, you will not need to add the -all_load linker flag to your projects anymore. If you were using this specifically for AdMob, you can now safely remove the flag from the “Other Linker Flags” section of your project’s “Build Settings”. You will still need to have the -ObjC linker flag in this section.

Identifier for Advertising

We are now also using Apple’s Identifier for Advertising for personalization and reporting. You will have to link against the AdSupport framework in your applications when using the AdMob SDK in order to support this feature. You can do this by adding the AdSupport.framework to the “Linked Framework and Libraries” section of your application’s Target settings. Make sure that you link the framework using the “Optional” setting if your application can run on an iOS version below iOS 6.

Auto Layout Support

Apple introduced Auto Layout for iOS 6 to help support multiple screen sizes. All of our AdMob banners have been updated to work with Auto Layout. When using Auto Layout (in code) with a GADBannerView, you must:

  • Remember to set the translatesAutoresizingMaskIntoConstraints property on the GADBannerView to NO
  • Make sure the GADBannerView’s frame is big enough to receive the ad type requested

We will release some sample code showcasing best practices when using Auto Layout very soon.
