@interface GADSearchBannerView : GADBannerView
A view that displays search ads. To show search ads: 1) Create a GADSearchBannerView and add it to your view controller’s view hierarchy. 2) Create a GADDynamicHeightSearchRequest object to hold the search query and other search data. 3) Call GADSearchBannerView’s -loadRequest: method with the GADDynamicHeightSearchRequest object.
If the banner view is initialized with kGADAdSizeFluid and the corresponding request is created with dynamic height parameters, this delegate will be called when the ad size changes.
