Set Strikethrough Attribute text for a currency formatted string in swift 3

Question

I am working with a label which shows the old price of a product with strikethrough attribute. I am trying to set the strikethrough property for the attributed string but could not get the actual result.

let price = 1000.0
let currencyFormatter = NumberFormatter()
currencyFormatter.numberStyle = .currency
currencyFormatter.currencyCode = "INR"
let priceInINR = currencyFormatter.string(from: price as NSNumber)

let attributedString = NSMutableAttributedString(string: priceInINR!)
            attributedString.addAttribute(NSStrikethroughStyleAttributeName, value: 1, range: NSMakeRange(0, attributedString.length))
            self.oldPriceLabel.attributedText = attributedString

Is there any way to set the currency formatter and strikethrough attributes simultaneously for a string?

Answer 1

Try this and see (Swift 3 & 4 compatible):

@IBOutlet var oldPriceLabel: UILabel!

func strikeOnLabel() {
    let price = 1000.0
    let currencyFormatter = NumberFormatter()
    currencyFormatter.numberStyle = .currency
    currencyFormatter.currencyCode = "INR"
    let priceInINR = currencyFormatter.string(from: price as NSNumber)

    let attributedString = NSMutableAttributedString(string: priceInINR!)

    // Swift 4.2 and above
attributedString.addAttribute(NSAttributedString.Key.strikethroughStyle, value: 2, range: NSMakeRange(0, attributedString.length))

// Swift 4.1 and below
attributedString.addAttribute(NSAttributedStringKey.strikethroughStyle, value: 2, range: NSMakeRange(0, attributedString.length))
    oldPriceLabel.attributedText = attributedString
}

Result:

₹1,000.00

For Swift 2:

let price = 1000.0
let currencyFormatter = NumberFormatter()
currencyFormatter.numberStyle = .currency
currencyFormatter.currencyCode = "INR"
let priceInINR = currencyFormatter.string(from: price as NSNumber)

let attributedString = NSMutableAttributedString(string: priceInINR!)

// Swift 4.2 and above
attributedString.addAttribute(NSAttributedString.Key.strikethroughStyle, value: 2, range: NSMakeRange(0, attributedString.length))

// Swift 4.1 and below
attributedString.addAttribute(NSStrikethroughStyleAttributeName, value: 2, range: NSMakeRange(0, attributedString.length))


self.oldPriceLabel.attributedText = attributedString

Answer 2

swift

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