The main reason for flickering is that, tableView is getting data to be attached late in time. So when you scroll, it takes time to switch from one type of tableViewCell to another. Plus you might be doing DB operations in cellForRowAtIndexPath which delays in returning tbaleViewCell. For implementing Smooth scrolling refer this
