Trouble Shoot: Programmatically add accessoryview to UITableViewCell messed up - ios

Question

I've stucked to this problem for couple days, and I've debugged it many times and can't figure out what's going wrong.
I have a UITableView that has three sections. I'd like to add buttons as accessoryView and UILabel as detailText to the second section.
It looked OK when View first loaded.
But after scroll it, it becomes
After couple scrolls, it freezes (not crash).
Below is my code, any advise will be appreciated.
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 3;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (section==0) {
return self.status.count;
}
else if (section==1)
return self.overrideCtrl.count;
else
return self.levelStatus.count;
// Return the number of rows in the section.
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"MenuCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSLog(#"section %#",indexPath);
if (indexPath.section == 0) {
cell.textLabel.text = [self.status objectAtIndex:indexPath.row];
NSLog(#"Status %#",cell.textLabel.text);
}
else if (indexPath.section == 1) {
cell.textLabel.text = [self.overrideCtrl objectAtIndex:indexPath.row];
cell.detailTextLabel.text =[NSString stringWithFormat:#"00:%02d",[[self.timeLeftArray objectAtIndex:indexPath.row] intValue]];//[[self.timeLeftArray objectAtIndex:indexPath.row] stringValue];
cell.accessoryView=[self.checkButtonArray objectAtIndex:indexPath.row];
NSLog(#"override %#",cell.textLabel.text);
}else{
cell.textLabel.text = [self.levelStatus objectAtIndex:indexPath.row];
NSLog(#"level %#",cell.textLabel.text);
}
return cell;
}
Thanks!

Answer 1

This problem is covered a lot on SO, it's because of cell reuse. You need to set the accessoryView to UITableViewCellAccessoryNone for your other sections, otherwise, a cell that was used for section one might be used in another section, and still have its accessory view.

Answer 2

You only have 1 CellIdentifier. You should have a different one for each section.
