斯威夫特 - 获取国家名单

问题描述

我怎样才能在斯威夫特的所有国家名称的数组？
我试着转换code我不得不在Objective-C，这是这样的：

How can I get an array with all countries names in Swift?I've tried to convert the code I had in Objective-C, which was this:

if (!pickerCountriesIsShown) {
    NSMutableArray *countries = [NSMutableArray arrayWithCapacity: [[NSLocale ISOCountryCodes] count]];

    for (NSString *countryCode in [NSLocale ISOCountryCodes])
    {
        NSString *identifier = [NSLocale localeIdentifierFromComponents: [NSDictionary dictionaryWithObject: countryCode forKey: NSLocaleCountryCode]];
        NSString *country = [[NSLocale currentLocale] displayNameForKey: NSLocaleIdentifier value: identifier];
        [countries addObject: country];
    }

和斯威夫特我不能从这里经过：

And in Swift I can't pass from here:

        if (!countriesPickerShown) {
        var countries: NSMutableArray = NSMutableArray()
        countries = NSMutableArray.arrayWithCapacity((NSLocale.ISOCountryCodes).count) // Here gives the Error. It marks NSLocale.ISOCountryCodes and .count

与你的人知道这件事吗？

Does anyone of you know about this?

感谢

推荐答案

首先 ISOCountry codeS 需要参数括号这样反而这将是 ISOCountry codeS（）。其次，你不需要围绕 NSLocale 和 ISOCountry codeS（）括号。此外，arrayWithCapacity是pcated这意味着它从语言除去德$ P $。这方面的一个工作版本会有点像这样

First of all ISOCountryCodes requires argument parenthesis so instead it would be ISOCountryCodes(). Second, you dont need parenthesis around NSLocale and ISOCountryCodes(). Also, arrayWithCapacity is deprecated meaning it is removed from the language. A working version of this would be somewhat like this

if (!countriesPickerShown) {
    var countries = NSMutableArray()
    countries = NSMutableArray(capacity: (NSLocale.ISOCountryCodes().count))
}
