For iOS 7 and higher, we recommend using the Google Mobile Ads SDK with Firebase.
If you need AdMob to support iOS 6, you can use the
Google-Mobile-Ads-SDK CocoaPod or download the
Mobile Ads SDK from this page and and include it manually.
Instead of downloading and installing the SDK directly, we recommend using CocoaPods to make it easier to manage library dependencies for your Xcode projects.
AdMob is now part of Firebase.
The Mobile Ads SDK for iOS utilizes Apple's advertising identifier (IDFA). The SDK uses IDFA under the guidelines laid out in the iOS developer program license agreement. You must ensure you are in compliance with the iOS developer program license agreement policies governing the use of this identifier.
We provide a number of sample apps that demonstrate the use of the Google Mobile Ads SDK. You can find these open source applications at this GitHub repository:iOS samples
