在swift 3中为货币格式化字符串设置删除线属性文本

Question

我正在使用一个标签,该标签显示具有删除线属性的产品的旧价格.我试图为属性字符串设置删除线属性,但无法获得实际结果.

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

有没有办法同时为字符串设置货币格式化程序和删除线属性？

Answer 1

试试这个并看看(Swift 3和4兼容):

@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
}

结果:

₹1,000.00

对于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

迅速

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