滾動視圖中的iAds

在我的應用程序中，我希望在具有導航欄和選項卡欄的表視圖控制器中顯示iAd。我可以在我的應用程序中顯示iAd，但是當我嘗試滾動時，此iAd出現問題，問題在於iAd也在滾動單元格，因此我無法查看底部的單元格。我正在使用下面的代碼創建iAd。有人能幫我解決以下問題。滾動視圖中的iAds

yes i got it you use addSubView which i think is wrong Add this Banner in last cell of a tableview or in a fotter of a table view if you are not use load more functionalty in you app 
– tableView:viewForFooterInSection: 
use that delegate method of table view UItableViewDelegate i think it helps you 
– tableView:heightForFooterInSection: 
add that method too to specify the height of footer of your table 
add the calculate banner size code in 
– tableView:heightForFooterInSection: 
and add banner in – tableView:heightForFooterInSection:
