How to Increase Line spacing in UILabel in Swift

Programatically add LineSpacing to your UILabel using following snippet.

Earlier Swift version

let attributedString = NSMutableAttributedString(string: "Your text")// *** Create instance of `NSMutableParagraphStyle`let paragraphStyle = NSMutableParagraphStyle()// *** set LineSpacing property in points ***paragraphStyle.lineSpacing = 2 // Whatever line spacing you want in points// *** Apply attribute to string ***attributedString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))// *** Set Attributed String to your label ***label.attributedText = attributedString

Swift 4.0

let attributedString = NSMutableAttributedString(string: "Your text")// *** Create instance of `NSMutableParagraphStyle`let paragraphStyle = NSMutableParagraphStyle()// *** set LineSpacing property in points ***paragraphStyle.lineSpacing = 2 // Whatever line spacing you want in points// *** Apply attribute to string ***attributedString.addAttribute(NSAttributedStringKey.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))// *** Set Attributed String to your label ***label.attributedText = attributedString

Swift 4.2

let attributedString = NSMutableAttributedString(string: "Your text")// *** Create instance of `NSMutableParagraphStyle`let paragraphStyle = NSMutableParagraphStyle()// *** set LineSpacing property in points ***paragraphStyle.lineSpacing = 2 // Whatever line spacing you want in points// *** Apply attribute to string ***attributedString.addAttribute(NSAttributedString.Key.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))// *** Set Attributed String to your label ***label.attributedText = attributedString

Programmatically:

SWift 4 & 4.2

Using label extension

extension UILabel {    func setLineSpacing(lineSpacing: CGFloat = 0.0, lineHeightMultiple: CGFloat = 0.0) {        guard let labelText = self.text else { return }        let paragraphStyle = NSMutableParagraphStyle()        paragraphStyle.lineSpacing = lineSpacing        paragraphStyle.lineHeightMultiple = lineHeightMultiple        let attributedString:NSMutableAttributedString        if let labelattributedText = self.attributedText {            attributedString = NSMutableAttributedString(attributedString: labelattributedText)        } else {            attributedString = NSMutableAttributedString(string: labelText)        }        // (Swift 4.2 and above) Line spacing attribute        attributedString.addAttribute(NSAttributedString.Key.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))        // (Swift 4.1 and 4.0) Line spacing attribute        attributedString.addAttribute(NSAttributedStringKey.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))        self.attributedText = attributedString    }}

Now call extension function

let label = UILabel()let stringValue = "Set\nUILabel\nline\nspacing"// Pass value for any one argument - lineSpacing or lineHeightMultiplelabel.setLineSpacing(lineSpacing: 2.0) .  // try values 1.0 to 5.0// or try lineHeightMultiple//label.setLineSpacing(lineHeightMultiple = 2.0) // try values 0.5 to 2.0

Or using label instance (Just copy & execute this code to see result)

let label = UILabel()let stringValue = "Set\nUILabel\nline\nspacing"let attrString = NSMutableAttributedString(string: stringValue)var style = NSMutableParagraphStyle()style.lineSpacing = 24 // change line spacing between paragraph like 36 or 48style.minimumLineHeight = 20 // change line spacing between each line like 30 or 40// Line spacing attributeattrString.addAttribute(NSAttributedStringKey.paragraphStyle, value: style, range: NSRange(location: 0, length: stringValue.characters.count))// Character spacing attributeattrString.addAttribute(NSAttributedStringKey.kern, value: 2, range: NSMakeRange(0, attrString.length))label.attributedText = attrString

Swift 3

let label = UILabel()let stringValue = "Set\nUILabel\nline\nspacing"let attrString = NSMutableAttributedString(string: stringValue)var style = NSMutableParagraphStyle()style.lineSpacing = 24 // change line spacing between paragraph like 36 or 48style.minimumLineHeight = 20 // change line spacing between each line like 30 or 40attrString.addAttribute(NSParagraphStyleAttributeName, value: style, range: NSRange(location: 0, length: stringValue.characters.count))label.attributedText = attrString

You can control the line spacing in storyboard.
