Question

我正在尝试从NSHTTPCookieStorage获取cookie并将其用于我的应用程序中的另一个URL。我正在从NSHTTPCookieStorage复制cookie，然后使用复制的cookie在NSHTTPCookieStorage中为不同的URL设置cookie。我正在尝试遵循代码，但是当我打印出其他URL的cookie时，没有。

    // authCookie is a cookie already in NSHTTPCookieStorage.
    NSURL *searchURL = [NSURL URLWithString:searchURLString];
    NSDictionary *authCookieProperties = [[[authCookie properties] copy] autorelease];
    NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionaryWithDictionary:authCookieProperties];

    [cookieProperties setObject:searchURL forKey:NSHTTPCookieDomain];
    [cookieProperties setObject:searchURL forKey:NSHTTPCookieOriginURL];
    NSHTTPCookie *searchCookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
    [sharedHTTPCookieStorage setCookie:searchCookie];
    [sharedHTTPCookieStorage setCookies:[NSArray arrayWithObject:searchCookie] 
                                 forURL:searchURL 
                        mainDocumentURL:nil];

    NSLog(@"Cookies for search = %@", [sharedHTTPCookieStorage cookiesForURL:searchURL]);
    NSLog(@"All Cookies = ");
    NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    for (NSHTTPCookie *cookie in [cookieJar cookies]) {
        NSLog(@"%@", cookie);
    }
    /*
    Console Output (With URL and cookie values hidden):
    Cookies for search = ()
    All Cookies = 
    <NSHTTPCookie version:0 name:"auth_token" value:"COOKIEVALUE" expiresDate:(null) created:2001-01-01 00:00:01 +0000 (1) sessionOnly:TRUE domain:"<search_url>" path:"/" isSecure:FALSE>
    <NSHTTPCookie version:0 name:"auth_token" value:"COOKIEVALUE" expiresDate:(null) created:2012-05-14 17:59:36 +0000 (3.58711e+08) sessionOnly:TRUE domain:"<URL_of_auth_cookie>" path:"/" isSecure:FALSE>
    */

如果您在新cookie中提供的值足够好，则必须保留制表符，因为根据Apple参考，如果初始化值以任何特定方式无效，则应返回nil。您可以在此处link进一步查看此信息。它有一个很好的方法从头开始创建一个cookie！
