Question

I know it is possible to set the height of all rows in a UITable but is it possible to set one row to be bigger than the others.
For example when the user touches on the cell with 2 fingers I want the cell to expand and show a description. But only that cell. Is that possible without overlapping the cells below it?

Answer 1

Use the UITableViewDelegate method heightForRowAtIndexPath

Say that your data model stored objects that have a height property:

 - ( void ) changeHeightForRowAtIndexPath: ( NSIndexPath *) indexPath ( NSInteger ) height {
    [ myData objectAtIndex: indexPath.row ].height = height;
    [ myTableView reloadRowsAtIndexPaths: [ NSArray arrayWithObject: indexPath ] withRowAnimation: UITableViewRowAnimationNone ];
 }
