推荐答案NSLocale类的 ISOCountryCodes()方法返回一个 [AnyObject] [String] 。从那里,你通过使用NSLocale的 displayNameForKey 方法获得国家名称。它看起来像这样:
You can get a list of countries using the NSLocale class's ISOCountryCodes() method which returns an array of [AnyObject] which you cast as [String]. From there, you get the country name by using NSLocale's displayNameForKey method. It looks like this:
var countries: [String] = [] for code in NSLocale.ISOCountryCodes() as [String] { let id = NSLocale.localeIdentifierFromComponents([NSLocaleCountryCode: code]) let name = NSLocale(localeIdentifier: "en_UK").displayNameForKey(NSLocaleIdentifier, value: id) ?? "Country not found for code: \(code)" countries.append(name) } println(countries)更多推荐
