iphone - Scroll View in Grid TabelView -
i m new iphone development , reason have query regarding how implement scroll view in table view m using following code

please in advance
i didn't read code, please reformat others can read easily.
what mean uiscrollview in uitableview? inside cells? still don't it. fyi uitableview inherits uiscrollview ...
what functionality want achieve? recommend read of samples given apple. there , extensive examples specially regarding uikit.
