14,957 PointsI don't have too much time to look at it now, but I see the problem. You're using the "dequeueReusableCellWithIdentifier" which in itself, is fine. But, if you try to log out "NSLog(@"%ld", (long)indexPath.row);" in the "- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath" method. You'll see the cells are reused. Which means as soon as you scroll, the button you added to one cell will be placed in another.

3,570 PointsNow I understand why but the question is, is there a way to make them stay? Any better approach to achieve this instead?

14,957 PointsI usually do this programmatically, but I'll have a look later today ;) Maybe Amit Bijlani has a good solution in the mean time?

3,570 PointsThanks but the button keeps on disappearing every time I scroll down the list as the cells are reused. As for the prepareForReused method, I honestly do not understand it and how I can make it work with what am trying to achieve.

3,264 PointsTry setting your hidden property to NO in prepareForReuse. So implement - (void)prepareForReuse in your TableViewController and set self.button.hidden = NO; and then of course set it to NO or YES according to your buy property when you configure the cell.
