推荐答案

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:
