Question

I want to expand a UITableViewCell with this function, calling from didSelectRowAtIndexPath:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {  
     if(selectedCellIndexPath != nil &&
       [selectedCellIndexPath compare:indexPath] == NSOrderedSame)
        return 128;  
    return 43;  
}

Clicking on a cell expands it, clicking on another cell collapses to old and expands the new cell. So far so good. But I also want to collapse the cell, when clicking on an expanded cell, and don’t know how?

As a bonus: the content of a not-expanded-cell is shown, overlapping the cell below. How can I prevent showing content that should be cropped by the size of a collapsed-cell?

Answer 1

Sounds like you just need to check in didSelectRowAtIndexPath:…, if indexPath is equal to selectedCellIndexPath, then set selectedCellIndexPath to nil.

You didn’t provide that code, so I’m just guessing.
