推荐答案

试用此代码：

商店：

func storeCookies() {
    let cookiesStorage = HTTPCookieStorage.shared
    let userDefaults = UserDefaults.standard

    let serverBaseUrl = "http://example.com"
    var cookieDict = [String : AnyObject]()

    for cookie in cookiesStorage.cookies(for: NSURL(string: serverBaseUrl)! as URL)! {
        cookieDict[cookie.name] = cookie.properties as AnyObject?
    }

    userDefaults.set(cookieDict, forKey: "cookiesKey")
}

检索：

func restoreCookies() {
    let cookiesStorage = HTTPCookieStorage.shared
    let userDefaults = UserDefaults.standard

    if let cookieDictionary = userDefaults.dictionary(forKey: "cookiesKey") {

        for (_, cookieProperties) in cookieDictionary {
            if let cookie = HTTPCookie(properties: cookieProperties as! [HTTPCookiePropertyKey : Any] ) {
                cookiesStorage.setCookie(cookie)
            }
        }
    }
}
