  1. POWhy subview of a UITableViewCell added incorrectly?
    text
    copied!<p>I have a problem. I implemented a table view. In <code>didSelectRowAtIndexPath</code> method I increase cell's height and add a textview to that cell's <code>contentView</code>. But if I scroll table view down(for 10 cells for example) I will see the same textview again. Can you please help me?</p> <p>here's some code for better understanding the problem:</p> <pre><code>- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if(selectedIndex == indexPath.row) { return CELL_HEIGHT * 5; } return CELL_HEIGHT; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:TRUE]; UITableViewCell *cell = [aTableView cellForRowAtIndexPath:indexPath]; if (selectedIndex == indexPath.row) { selectedIndex = -1; [[cell.contentView viewWithTag:COOL_TAG] removeFromSuperview]; } else { UITableViewCell *previousCell = [aTableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:selectedIndex inSection:0]]; if ([previousCell.contentView viewWithTag:COOL_TAG]) { [[previousCell.contentView viewWithTag:COOL_TAG] removeFromSuperview]; } selectedIndex = indexPath.row; UITextView *text = [[UITextView alloc] initWithFrame:CGRectMake(10, 45, 255, 180)]; [text.layer setBackgroundColor:[[UIColor whiteColor] CGColor]]; [text.layer setBorderColor:[[UIColor grayColor] CGColor]]; [text.layer setBorderWidth:1.0f]; [text.layer setCornerRadius: 8.0f]; [text.layer setMasksToBounds:YES]; [text setEditable:NO]; text.text = [questionArray objectAtIndex:indexPath.row]; text.tag = COOL_TAG; [cell.contentView addSubview:text]; } [tableView beginUpdates]; [tableView endUpdates]; } </code></pre> <p>Thanks in advance!</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
