DidSelectRowAtIndexPath with section

I have a UITableView to which I have assigned sections. When using didSelectRowAtIndex with indexPath.row I do not get the correct value. Let's say I'm in section 2, then it starts the row index again at 0, and so I get the wrong index.

Can someone tell me how to fix this? I understand that you can get the index of the indexPath.section section, but I cannot figure out how to use this.

bandDetailViewController.band = [self.programArray objectAtIndex:indexPath.row];

I hope you help me. Thanks in advance: -)

EDIT:

Sample data. My cells for table view are loaded from this plist.

If you have implemented

tableview cellForRowAtIndexPath

then didSelectRowAtIndexPathyou can call this method to retrieve the selected value. No need to rebuild your data structures if it is too complicated. This is what I ended up with variable length sections and it works fine.

NSString *selectedValue = [self tableView:theTableView cellForRowAtIndexPath:indexPath].textLabel.text;

If you look at the NSIndexPath documentation , you will see how the NSIndexPath data structure is laid out.

To get the section number, you want to do something like:

[indexPath indexAtPosition:0]

To get the string in this section:

[indexPath indexAtPosition:1]
