objective c - How to control the line spacing in UILabel

In Xcode 6 you can do this in the storyboard:

I thought about adding something new to this answer, so I don't feel as bad... Here is a Swift answer:

import Cocoa  let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.lineSpacing = 40  let attrString = NSMutableAttributedString(string: "Swift Answer") attrString.addAttribute(.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attrString.length))  var tableViewCell = NSTableCellView() tableViewCell.textField.attributedStringValue = attrString 

"Short answer: you can't. To change the spacing between lines of text, you will have to subclass UILabel and roll your own drawTextInRect, or create multiple labels."

This is a really old answer, and other have already addded the new and better way to handle this.. Please see the up to date answers provided below.

Starting from iOS 6 you can set an attributed string to the UILabel. Check the following :

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:label.text]; NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init]; paragraphStyle.lineSpacing = spacing; [attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, label.text.length)];  label.attributedText = attributedString; 

The solutions stated here didn't work for me. I found a slightly different way to do it with the iOS 6 NSAttributeString:

myLabel.numberOfLines = 0;  NSString* string = @"String with line one. \n Line two. \n Line three."; NSMutableParagraphStyle *style  = [[NSMutableParagraphStyle alloc] init]; style.minimumLineHeight = 30.f; style.maximumLineHeight = 30.f; NSDictionary *attributtes = @{NSParagraphStyleAttributeName : style,}; myLabel.attributedText = [[NSAttributedString alloc] initWithString:string                                                          attributes:attributtes];    [myLabel sizeToFit]; 

From Interface Builder (Storyboard/XIB):

Programmatically:

SWift 4

Using label extension

extension UILabel {      // Pass value for any one of both parameters and see result     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)         }          // 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 = "How to\ncontrol\nthe\nline spacing\nin UILabel"  // Pass value for any one argument - lineSpacing or lineHeightMultiple label.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 = "How to\ncontrol\nthe\nline spacing\nin UILabel" let attrString = NSMutableAttributedString(string: stringValue) var style = NSMutableParagraphStyle() style.lineSpacing = 24 // change line spacing between paragraph like 36 or 48 style.minimumLineHeight = 20 // change line spacing between each line like 30 or 40  // Line spacing attribute attrString.addAttribute(NSAttributedStringKey.paragraphStyle, value: style, range: NSRange(location: 0, length: stringValue.characters.count))  // Character spacing attribute attrString.addAttribute(NSAttributedStringKey.kern, value: 2, range: NSMakeRange(0, attrString.length))  label.attributedText = attrString 

Swift 3

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