Q:

How to install GoogleAds-IMA-iOS-SDK-For-AdMob old pod version 3.0.beta.6? 

Recently google decided to update this pod (GoogleAds-IMA-iOS-SDK-For-AdMob) to 3.0.beta.7 making some changes that are breaking my app that is using 3.0.beta.6.  I tried to install the old version by setting specifically it in my podfile  but still doesn't care and it installs the new one.  
The question is: 

Is there any way to install an old version of this pod?  
Is google using a wrong syntax what makes cocoapods not to understand the version?  

A:

If you want to get the latest version you would use 
pod 'GoogleAds-IMA-iOS-SDK-For-AdMob'
To pull in a specific version you'd want 
pod 'GoogleAds-IMA-iOS-SDK-For-AdMob', '3.0.beta.6'
A bit more info about pod versioning is available at http://guides.cocoapods.org/using/the-podfile.html
