iOS 10.3: NSStrikethroughStyleAttributeName is not rendered if applied to a sub range of NSMutableAttributedString

Adding a NSBaselineOffsetAttributeName, as explained here, to the attributed string brings back the strikethrough line. Overriding drawText:in: can be slow especially on Collection View or Table View Cells.

How can I create a UILabel with strikethrough text?

SWIFT 5 UPDATE CODE

let attributeString: NSMutableAttributedString = NSMutableAttributedString(string: "Your Text")
    attributeString.addAttribute(NSAttributedString.Key.strikethroughStyle, value: 2, range: NSRange(location: 0, length: attributeString.length))

then:

yourLabel.attributedText = attributeString

To make some part of string to strike then provide range

let somePartStringRange = (yourStringHere as NSString).range(of: "Text")
attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: somePartStringRange)

Objective-C

In iOS 6.0 > UILabel supports NSAttributedString

NSMutableAttributedString *attributeString = [[NSMutableAttributedString alloc] initWithString:@"Your String here"];
[attributeString addAttribute:NSStrikethroughStyleAttributeName
                        value:@2
                        range:NSMakeRange(0, [attributeString length])];

Swift

let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: "Your String here")
attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: NSMakeRange(0, attributeString.length))

Definition :

- (void)addAttribute:(NSString *)name value:(id)value range:(NSRange)aRange

Parameters List:

name : A string specifying the attribute name. Attribute keys can be supplied by another framework or can be custom ones you define. For information about where to find the system-supplied attribute keys, see the overview section in NSAttributedString Class Reference.

value : The attribute value associated with name.

aRange : The range of characters to which the specified attribute/value pair applies.

Then

yourLabel.attributedText = attributeString;

For lesser than iOS 6.0 versions you need 3-rd party component to do this.
One of them is TTTAttributedLabel, another is OHAttributedLabel.

Why strikethrough is not working in iOS 14

Adding baselineOffset with value 0 to the attributed string brings back the strikethrough line. More details can be found on apple dev forum and this SO thread.

attributeString.addAttribute(NSAttributedString.Key.baselineOffset, value: 0, range: totalNsString.range(of: strikeString))

NSMutableAttributedString not working in tableviewcell with a specific range

Try this,

   let strOriginalPrice = "my price"
    let strdiscountedPrice = "discounted price"
    let strPrice = strOriginalPrice+" "+strdiscountedPrice

 //        let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: strPrice)
//        attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: NSMakeRange(0, attributeString.length))

    let attributedDiscunt: NSMutableAttributedString =  NSMutableAttributedString(string: strPrice)
    attributedDiscunt.addAttribute(NSStrikethroughStyleAttributeName, value:2, range: NSMakeRange(0, strOriginalPrice.characters.count-1))
    attributedDiscunt.addAttribute(NSBaselineOffsetAttributeName, value: 0, range: NSMakeRange(0, strOriginalPrice.characters.count-1))

    cell.lblPrice.attributedText = attributedDiscunt
