快速获取当地货币

Question

我正在为多个国家的应用程序商店设立一个小小的。我怎么能弄清楚我必须以美元，欧元等价格出现... 我认为它与localeIdentifier有关，但我不知道如何处理这个

Answer 1

您可以使用

从"field_name": { "type": "string", "index": "not_analyzed" } 获取货币符号和代码

Swift 1和2

(NS)Locale

Swift 3

let locale = NSLocale.currentLocale()
let currencySymbol = locale.objectForKey(NSLocaleCurrencySymbol)!
let currencyCode = locale.objectForKey(NSLocaleCurrencyCode)!

Swift 3.1

let locale = Locale.current()
let currencySymbol = locale.object(forKey: .currencySymbol)!
let currencyCode = locale.object(forKey: .currencyCode)!

这与用户区域格式设置相关，适用于let locale = Locale.current let currencySymbol = locale.currencySymbol! let currencyCode = locale.currencyCode! 和iOS

Answer 2

for swift3

//User region setting return
let locale = Locale.current //NSLocale.current

//Returns true if the locale uses the metric system (Note: Only three countries do not use the metric system: the US, Liberia and Myanmar.)
let isMetric = locale.usesMetricSystem

//Returns the currency code of the locale. For example, for “zh-Hant-HK”, returns “HKD”.  
let currencyCode  = locale.currencyCode

//Returns the currency symbol of the locale. For example, for “zh-Hant-HK”, returns “HK$”.
let currencySymbol = locale.currencySymbol
