Scroll view delegate methods app is crashing - iphone

Question

If i move the scroll view horizontally it has to show new table with new labels inside it with one question at a time..The number of questions may be 10 or 20..means we have to create new table and new labels every time when scroll view moves horizontally..
First time when user selects the category the delegate method will call.In this method also i am creating table view and labels as shown below only..

It is working fine in simulator but in iPad for some time it is working fine while scrolling
after scrolling 15 or 20 times it is crashing..
Some times when running with instruments also crash log not showing anything and sometimes it is showing memory warning..
