How to set a space between characters and lines in UILabel

Question

I'd like set one spacing between first and second lines, between other lines need another spacing. With this, second and next lines must have specific character spacing.

This all need doing in one control. How i can do this? I decided to create a separate UILabel for each row but i think it's wrong way.

Answer 1

You can't change the spacing between lines of text, you will have to subclass UILabel and roll your own drawTextInRect, create multiple labels, or use a different font.

But there are two custom Labels, that allow you to control the lineheight.

Hope this helps...

In iOS6, you could do this:

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle setLineSpacing:40];
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [labelText length])];
cell.label.attributedText = attributedString ;

Try this, it should work for you (with Swift 4)

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(NSAttributedStringKey.paragraphStyle, value: style, range: NSRange(location: 0, length: stringValue.characters.count))
// add strike
attrString.addAttribute(NSAttributedStringKey.strikethroughStyle, value: 2, range: NSMakeRange(0, attrString.length))
// add space between characters
attrString.addAttribute(NSAttributedStringKey.kern, value: 2, range: NSMakeRange(0, attrString.length))
label.attributedText = attrString

Result:
