(NSInteger) tableView:(UITableView *) tableView numberOfRowsInSection:(NSInteger) section { return [self.chaptersList count]; }

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

cell.textLabel.text = [chaptersList objectAtIndex:row]; cell.textLabel.font = [UIFont boldSystemFontOfSize:14]; cell.accessoryType = (row == oldRow && lastIndexPath != nil) ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;

return cell; }

pragma mark - pragma mark Table Delegate Methods (void) tableView:(UITableView *) tableView didSelectRowAtIndexPath:(NSIndexPath *) indexPath { int row = [indexPath row]; int oldRow = [lastIndexPath row]; if (row != oldRow) { UITableViewCell *newCell = [tableView cellForRowAtIndexPath:indexPath]; newCell.accessoryType = UITableViewCellAccessoryCheckmark;

UITableViewCell *oldCell = [tableView cellForRowAtIndexPath: lastIndexPath]; oldCell.accessoryType = UITableViewCellAccessoryNone;

lastIndexPath = indexPath; }

[tableView deselectRowAtIndexPath:indexPath animated:YES]; }

Answer 1

in didSelectRow Method at the end of code , try this

[tableView reloadData]; or

[self.view setNeedsDisplay];
