从IOS的国家/地区名称获取国家/地区代码 [英] Get country code from country name in IOS
问题描述
我用英语从服务器检索国家/地区名称。例如,西班牙
Im retrieving a country name from a server in english. For example, "Spain"
我想要做的是,假设国家名称将以英文书写,请获取国家/地区代码。
What I want to do is, assuming the country name is going to be written in english, get the country code.
我该怎么办?我发现从国家代码中获取国家名称非常简单,但我不知道如何进行相反的操作。
What should I do? I´ve found getting the country name from the country code quite easy, but I´ve got no idea of how to do the opposite operation.
非常感谢。

杰夫的答案在这里有所帮助,只需稍加补充。
Jef's answer helped here, with slight additions.
NSArray *countryCodes = [NSLocale ISOCountryCodes];
NSMutableArray *countries = [NSMutableArray arrayWithCapacity:[countryCodes count]];
for (NSString *countryCode in countryCodes)
{
NSString *identifier = [NSLocale localeIdentifierFromComponents: [NSDictionary dictionaryWithObject: countryCode forKey: NSLocaleCountryCode]];
NSString *country = [[[NSLocale alloc] initWithLocaleIdentifier:@"en_UK"] displayNameForKey: NSLocaleIdentifier value: identifier];
[countries addObject: country];
}
NSDictionary *codeForCountryDictionary = [[NSDictionary alloc] initWithObjects:countryCodes forKeys:countries];
现在浏览'codeForCountryDictionary',其中包含您需要代码的国家/地区的名称,例如,
Now go through the 'codeForCountryDictionary' with the name of the country for which you require the code, for example,
NSLog(@"%@",[codeForCountryDictionary objectForKey:@"Spain"]);
将结果显示为'ES',这是西班牙的2个字母的国家代码。
would yield the result as 'ES', which is the 2 letter country code for spain.
