Answer 1

Use attributeString
Screenshot
Code
NSDictionary * attribtues = #{NSStrikethroughStyleAttributeName:#(NSUnderlineStyleSingle),
NSStrikethroughColorAttributeName:[UIColor redColor]};
NSAttributedString * attr = [[NSAttributedString alloc] initWithString:#"label" attributes:attribtues];
self.label.attributedText = attr;

Answer 2

Updated function from #krunal answer for Swift4
extension String {
func strikeThrough() -> NSAttributedString {
let attributeString = NSMutableAttributedString(string: self)
attributeString.addAttribute(NSAttributedString.Key.strikethroughStyle, value: NSUnderlineStyle.single.rawValue, range: NSMakeRange(0,attributeString.length))
return attributeString
}
}
and to call the function is the same
yourLabel.attributedText = "yourString".strikeThrough()

Answer 3

For Programatically Use Below Code
Prefer to Use Extension:
extension String {
func strikeThrough() -> NSAttributedString {
let attributeString = NSMutableAttributedString(string: self)
attributeString.addAttribute(NSAttributedStringKey.strikethroughStyle, value: NSUnderlineStyle.styleSingle.rawValue, range: NSMakeRange(0,attributeString.length))
return attributeString
}
}
And call this Function
myLabel.attributedText = "my string".strikeThrough()
And Result look like this.

Answer 4

If wanting to use a UILabel extension
extension UILabel {
func strikeThroughText() {
let attributeString = NSMutableAttributedString(string: self.text ?? "")
attributeString.addAttribute(NSAttributedString.Key.strikethroughStyle, value: NSUnderlineStyle.single.rawValue, range: NSMakeRange(0,attributeString.length))
self.attributedText = attributeString
}
}
