How to programmatically select text in a UITextField without "range selectors" on the side

Question

I have a UITextField in my application that is in a UITableView and I want their text to be UITextField when I click on them, because usually users will want to erase what they already have before entering new text. I have successfully done this, but the fact is that when the text is highlighted, these ugly little blue “lollipops” used to select the range of the selected text appear on the sides of the text. How can I make them not appear? Thanks!

my code (qty and numberOfPeople is a UITextField ):

 -(void)textFieldDidBeginEditing:(UITextField *)textField { for (NSInteger i=0; i<n; i++){ NSIndexPath *indexPath = [NSIndexPath indexPathForItem:i inSection:0]; CustomCell *cell = (CustomCell *) [self.itemTable cellForRowAtIndexPath:indexPath]; if ([textField isEqual:cell.qty] || [textField isEqual:cell.numberOfPeople]){ [textField selectAll:self]; } } }
