Question

I am using UITableViewCellAccessoryDisclosureIndicator as accessoryType of my UITableViewCell. According to Apple’s documentation, the data source method

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath 

should automatically get called.

If the cell is enabled and the accessory type is UITableViewCellAccessoryDetailDisclosureButton, the accessory view tracks touches and, when tapped, sends the data-source object a tableView:accessoryButtonTappedForRowWithIndexPath: message.

here’s my code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
[cell.textLabel setText:[datasource objectAtIndex:indexPath.row]];

cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

return cell;
}

The data source method is just a NSLog but nothing is printed…

Am I missing something? (of course, data source and delegate are set properly)

Answer 1

The answer is in your question. You said

I am using UITableViewCellAccessoryDisclosureIndicator as
accessoryType …

and you quoted the Apple docs in part

If the cell is enabled and the accessory type is UITableViewCellAccessoryDetailDisclosureButton …

Only when you use UITableViewCellAccessoryDetailDisclosureButton is the delegate method called. The difference, of course, is that this is a button, where UITableViewCellAccesssoryDisclosureIndicator is not. When you use the latter, tapping it is like tapping the cell itself. You could create a custom cell and implement hitTest: to determine if the tap was “near” the disclosure indicator, but that seems like more work than necessary (unless you really don’t want to use a detail disclosure button).
