在Swift的UIButton内是否可以添加两个标签？

Question

I have an UIButton on my Swift project and I would like to use a font-awesome icon combined with a text inside of it.

I know that I can set a title to the button but, as far I need that the icon and the text will be in a different text-size, I cannot combine them in the same title tag. I also have thought about to use an image (to set the font-awesome icon) with an attributed title but then I cannot change the color of the font-awesome icon.

I know that I can get this behaviour adding two labels inside an UIView but I would like to know if it is possible to get this on an UIButton .

Thanks in advance!

Answer 1

You can set attributed title of your button with attribute string something like,

 let attributedTitle = NSAttributedString(string: "Click Here",
attributes: [NSForegroundColorAttributeName : UIColor.blueColor()])
button.setAttributedTitle(attributedTitle, forState: .Normal)

You can set multiple color,font,size for particular texts or part of string.

another example,

 attributedTitle = NSMutableAttributedString(string: @"Click Here", attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 18.0)!])

   attributedTitle.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor(), range: NSRange(location:2,length:4))

  button.setAttributedTitle(attributedTitle, forState: .Normal)

So, you can specify location by using NSRange and can set different color and font attributes for specified range!
