ios - UILabel Text with Multiple Font Colors

Is there a way to have the textColor property of a UILabel be two different UIColors? Basically I'm trying to make the first character in the UILabel text property to be greenColor and the rest be blackColor. I would like to avoid using two different UILabels because I may want to change the position in the text of the green character.

Starting from ios 6 you can do the following :

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]  initWithString:string];
[attributedString addAttribute:NSBackgroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,3)];
[attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(4,9)];
cell.label.attributedText = attributedString;
