Since iOS 6.0 you can use NSAttributedString with UIButton.

//create an underlined attributed string
NSAttributedString *titleString = [[NSAttributedString alloc] initWithString:@"Title" attributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle | NSUnderlinePatternSolid)}];

//use the setAttributedTitle method
[yourButton setAttributedTitle:titleString forState:UIControlStateNormal];
