Subscript and superscript text is a Swift Extension for Swift 4 which provides easy creation of a custom superscripted or subscripted text for a UILabel from a String to a NSMutableAttributedString. This extension is great if you are developing an app with scientific purposes, where you have to write equation or unit of measure.
Using the function customText, you'll easily create a perfect custom subscript or superscript text.
SUPERSCRIPT: put the word, or phrase, you need to elevate between two braces, { and }
SUBSCRIPT: put the word, or phrase, you need to subscript between £ and $
Here's a code example
let myLabel1 = UILabel()
let myLabel2 = UILabel()
var subScriptText = "(H£2$) 0.117 kJ/mol"
var superScriptText = "−1.88·10{−6} cm{3}/mol (298 K)"
var finalSubScript : NSMutableAttributedString = subScriptText.customText()
var finalSuperScript : NSMutableAttributedString = superScriptText.customText()
myLabel1.attributedText = finalSubScript
myLabel2.attributedText = finalSuperScriptThe result will be:
Subscript:
Superscript:
