What code are you using to show your AdMob ad?

 SonarCocosHelper::IOS::Setup();
  SonarCocosHelper::AdMob::showBannerAd();

this above 2 line

That’s the problem, by default the showBannerAd method displays an ad at the top of the screen but you haven’t set 

SCH_AD_MOB_TOP_BANNER_AD_UNIT_ID

Either set that or if you want to display it at the bottom call 

SonarCocosHelper::AdMob::showAdMobBanner( AdBannerPosition::eBottom )

ok done ….but  i want to change the dimension of add then where is the change for that??

We don’t have that built in ATM, you can change the native code as it’s an open source.

ok sir ..Thank you  for help me

Your very welcome :D
