var uname:String= "abcdefg hijklmn opq rst uvw xyz"

varmyMutableString =NSMutableAttributedString()

myMutableString =NSMutableAttributedString(string: uname, attributes: [NSFontAttributeName:UIFont(name:"Georgia", size:14.0)!])

添加不同字体颜色

myMutableString.addAttribute(NSForegroundColorAttributeName, value:FfontColor, range:NSRange(location:1,length:4))

//添加不同字体大小

myMutableString.addAttribute(NSFontAttributeName, value:UIFont.systemFontOfSize(12.0), range:NSRange(location:1,length:4))

Uname.attributedText= myMutableString
