IOS中根据国家名称获取国家代码

如何在IOS中根据国家名称获取国家代码

swift
import Foundation
func getCountryCodeByCountryName(countryName: String) -> String? {
    let locale = NSLocale.current
    let countryCodes = NSLocale.isoCountryCodes
    
    for countryCode in countryCodes {
        let country = locale.displayName(forKey: .countryCode, value: countryCode)
        if country?.localizedCaseInsensitiveContains(countryName) == true {
            return countryCode
        }
    }
    
    return nil
}
// 示例用法
let countryName = "中国"
if let countryCode = getCountryCodeByCountryName(countryName: countryName) {
    print("国家名称: \(countryName)，国家代码: \(countryCode)")
} else {
    print("找不到对应的国家代码")
}

swift
import Foundation
func getCountryNameByCountryCode(countryCode: String) -> String? {
    let locale = NSLocale.current
    let countryCodes = NSLocale.isoCountryCodes
    
    for code in countryCodes {
        if code == countryCode {
            let country = locale.displayName(forKey: .countryCode, value: code)
            return country
        }
    }
    
    return nil
}
// 示例用法
let countryCode = "CN"
if let countryName = getCountryNameByCountryCode(countryCode: countryCode) {
    print("国家代码: \(countryCode)，国家名称: \(countryName)")
} else {
    print("找不到对应的国家名称")
}
