UILabel: Custom underline color?

Question

I need the text of a UILabel to be black, but have a light gray underline under the text. Is this possible with NSAttributedString or TTTAttributedLabel? Or is custom drawing using Core Graphics needed?

CLARIFICATION: I need a specific color text on a different color underline. Example: blue text on red underline.

You can do with NSAttributedString as below.

NSMutableAttributedString* string = [[NSMutableAttributedString alloc]initWithString:@"you string"];
[string addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, string.length)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, string.length)];//TextColor
[string addAttribute:NSUnderlineStyleAttributeName value:underlineNumber range:NSMakeRange(0, string.length)];//Underline color
[string addAttribute:NSUnderlineColorAttributeName value:[UIColor lightGrayColor] range:NSMakeRange(0, string.length)];//TextColor
 yourlabel. attributedText = string;

Note: You can also underline particular range of string as like in this post. Also note down, it works ios6+ only.
