Question

I have a list of text items which populate a list. The code for it looks like this:

// CREATING EACH CELL IN THE LIST
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"business";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if(!cell){
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
        cell.textLabel.font = [UIFont fontWithName:@"Helvetica" size:17];
        cell.textLabel.numberOfLines = 0;
        cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
    }



    cell.textLabel.text = [cellTitleArray objectAtIndex:indexPath.row];


    // CLOSE THE SPINNER
    [spinner stopAnimating];

    // return the cell for the table view
    return cell;
}




-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIFont *cellFont = [UIFont fontWithName:@"Helvetica" size:17];
    CGSize constraintSize = CGSizeMake(self.itemList.frame.size.width, MAXFLOAT);

    CGSize labelSize = [[cellTitleArray objectAtIndex:indexPath.row] sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];

    return labelSize.height + 30;
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{    

}

What I want to do is to give the person a choice to edit each item. One way it makes sense to do that is by making it a 2-column list and on the right side column to make a character like “>” so they can tap it and it will give them an option to edit the item.

How can that be done in this case?

Thanks!

To capture a row click:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // Use indexPath.row to find your selection
    ...
}

If you watch to capture a click on just a button, or similar:

[self.buttono addTarget:self action:@selector(doAction) forControlEvents:UIControlEventTouchUpInside];

If you wish to use the accessoryType, you would place this code in your cellForRowAtIndexPath method.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    // Pick an indicator to suit your need/look
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}

Then you action something on the click like so

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
    // Perform action for this click on row indexPath.row
}

If you indexPath.row isn’t enough to differentiate between your clicks (I can’t see why it wouldn’t be!) then you can always use setTag on your disclosure button.
