Question

I have this bizarre problem. I’m making a checklist program with XCode and I’m using UITableView with UITableViewCellAccessoryCheckmark. I can select cells and the checkmark will appear, but somehow, other cells that I have NOT yet selected below will also have a checkmark appear. Any ideas?
Here’s my check mark coding:

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell;
cell = [aTableView cellForRowAtIndexPath: indexPath];
cell.accessoryType = UITableViewCellAccessoryCheckmark; 

}

I don’t know if this affects it, but I also implemented this method:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *CellIdentifier = @"CellIdentifier";

// Dequeue or create a cell of the appropriate type.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    cell.accessoryType = UITableViewCellAccessoryNone;
}

// Configure the cell.
if(tableView == Table1){

    switch(indexPath.section){
        case 0:
            cell.textLabel.text = [array1 objectAtIndex:indexPath.row];
            break;
        case 1:
            cell.textLabel.text = [array2 objectAtIndex:indexPath.row];
            break;
        case 2:
            cell.textLabel.text = [array3 objectAtIndex:indexPath.row];
            break;
    }

    //cell.textLabel.text = [NSString stringWithFormat:@"Row %d", indexPath.row];
}
if(tableView == Table2){
    cell.textLabel.text = [array4 objectAtIndex:indexPath.row];
}
return cell;

}

Thanks.

Set the cell.accessoryType each time you call tableView:cellForRowAtIndexPath:. Otherwise, when you reuse a cell, you’ll get it’s accessoryView instead of what you’re expecting.

So, yeah, you’ll need to keep track in when NSIndexPaths are selected by some method other than just looking at the accessoryType.
