{
 //force the layout before the drawing cycle begins, so that when the tableview setup its cells the subviews of the cell 
 already have the frame information of the cell. For example, with this line, the text view inside the cell can use 
 the cell width to calculate depth to accormodate its text.
    [self.view layoutIfNeeded];
    [self.tableView reloadData];
