ios - NSNumberFormatter 格式货币不起作用

Question

我有一个数字格式化程序:

let currencyFormatter:NSNumberFormatter = NSNumberFormatter()
        currencyFormatter.numberStyle = NSNumberFormatterStyle.CurrencyStyle
        currencyFormatter.currencyCode = "$"

为标签设置:

cell.ValueLabel.text = currencyFormatter.stringFromNumber(product.price)

并得到 100.00 而不是 100.00$

Answer 1

您必须设置 currencySymbol 而不是 currencyCode

let currencyFormatter = NSNumberFormatter()
currencyFormatter.numberStyle = .CurrencyStyle
currencyFormatter.currencySymbol = "$"
currencyFormatter.stringFromNumber(100)  // $100.00"

其他

let currencyFormatter = NSNumberFormatter()
currencyFormatter.numberStyle = .CurrencyStyle
currencyFormatter.currencyCode = "USD"
currencyFormatter.stringFromNumber(100)  // $100.00"
