Strikethrough thickness for NSMutableAttributedString

I am annotating a mutable attributed string with a strikethrough in objective-c. Using the following code.

[MAString addAttribute:NSStrikethroughStyleAttributeName
                     value:[NSNumber numberWithInt:1]
                     range:NSMakeRange(0, [text length])]

I am not clear what the value parameter controls and what its possible values are. Does it control thickness? If so, what are the possible values?

This answer is for lazy programmers

extension String {

/// Apply strike font on text
    func strikeThrough(lineThickness:Int,lineColor:UIColor) -> NSAttributedString {
  let attributeString = NSMutableAttributedString(string: self)
    attributeString.addAttribute(
    NSAttributedString.Key.strikethroughStyle,
    value: lineThickness,
    range: NSRange(location: 0, length: attributeString.length))
    attributeString.addAttribute(
    NSAttributedString.Key.strikethroughColor,
    value: lineColor,
    range: NSRange(location: 0, length: attributeString.length))
    return attributeString
   }
 }

Usage

yourlabel.attributedText = "your text".strikeThrough(lineThickness: 3, lineColor: .red)

What about having a look to the documentation?

This value indicates whether the text has a line through it and corresponds to one of the constants described in NSUnderlineStyle. The default value for this attribute is styleNone.

And then:
