Have half a UILabel text bold and half not?

问题:

I want half of my UILabel's text to be bold and half to not be bold. How can I do this?

回答1:

NSAttributedString allows for specification of formatting within a string, but sadly, UIKit does not yet do anything with this. However, there are a few open-source implementations that do. Check out OHAttributedLabel.

回答2:

You can't do this easily unless you subclass UILabel and mess with the subviews. Better to use two UILabels instead. Found another thread about it here.

UILabel has attributedText which takes a NSAttributedString which allows you to customize multiple aspects of a string including changing the font type and other attributes

  var attributedString = NSMutableAttributedString(attributedString: NSAttributedString(string: "Not Bold"))

  let boldAttrString = NSAttributedString(string: "BOLD", attributes: [NSFontAttributeName: UIFont(name: "Avenir-Medium", size: 15)!])
  attributedString.appendAttributedString(boldAttrString)
  myLabel.attributesText = attributedString
