indentationLevel property doesn't appear to do anything?

Question

I'm have a number rows I'm inserting into a table using -insertRowsAtIndexPaths:withRowAnimation, and I would like the rows to be indented from the left to distinguish them from the rest of the cells. The indentationLevel property of UITableViewCell looks like it's exactly what I need, but it doesn't seem to do anything. Here's the code I'm using to set the indentation level (dot syntax doesn't make a difference):

[cell setIndentationWidth:10];
[cell setIndentationLevel:1];

Is indentationLevel what I want, or should I be looking elsewhere?

Answer 1

Everything I've read suggests that's how you're supposed to do it. Make sure that you aren't creating a new cell with the same pointer later on in the code (after you set the indentation, but before it gets drawn). Have you tried setting the indentation to something larger that would be more noticeable on the screen (say, 100px instead of 10)?

Answer 2

You may be over-riding its implementation in your cells. in

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

try:

    if (cell == nil) { 
 cell = (UITableViewCell*)[[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"cellType01"] autorelease]; 
 [cell setIndentationLevel:indexPath.row];
 [cell setIndentationWidth:10];
 cell.selectionStyle = UITableViewCellSelectionStyleNone;
 // Tag the view 
 [[[cell subviews] objectAtIndex:0] setTag:111]; 
 UILabel* labelView = [[UILabel alloc] initWithFrame: CGRectMake(cell.indentationLevel*cell.indentationWidth, 0, 300, 20)];

}

Answer 3

indentationLevel and indentationWidth affect the positioning of the standard items textLabel, detailTextLabel, and imageView. They do not affect the origin of contentView's frame.

If you are not using textLabel, etc. (perhaps because targeting iPhone OS 2), you need to handle the indentation manually, as the previous answer shows.
