PHP cookie 未在 uiwebview 中保持设置

Question

我有一个具有登录名的 UIWebView。登录是一个 PHP 脚本并且有一个 setcookie() 函数。 cookie 是在我登录（在 webview 中）但当我关闭应用程序（使用 webview）并重新打开它时设置的。 PHP cookie 未设置，我必须重新登录。

这是 PHP 代码

setcookie($_SESSION['id'], $_SESSION['user_name'], time() + (86400 * 3), "/"); 
setcookie($_SESSION['pro_pic'], $_SESSION['status'], time() + (86400 * 3), "/"); 
setcookie($_SESSION['pro_pic'], $_SESSION['email'], time() + (86400 * 3), "/"); 

UIWebivew 代码

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIWebView *webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];

    NSString *url=@"http://server.bithumor.co/bitpicks/index1.php";
    NSURL *nsurl=[NSURL URLWithString:url];
    NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];

    [webview loadRequest:nsrequest];

    webview.scrollView.bounces = NO;

    [self.view addSubview:webview];
    [self.view bringSubviewToFront:webview];
}

在普通的 Safari 网络浏览器上，cookie 保持设置并完美运行。但它在 UIWebView 中不起作用。

我使用什么 Objective-c（仅限）代码来设置 PHP cookie，这样我就不必再次登录了？

正如Keep losing php session cookie in UIWebView这里指出的那样，我更新了你的代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIWebView *webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];

    NSString *url=@"http://server.bithumor.co/bitpicks/index1.php";
    NSURL *nsurl=[NSURL URLWithString:url];
    NSMutableURLRequest *nsrequest=[NSMutableURLRequest requestWithURL:nsurl];

    NSString *cookiesSaved = [[NSUserDefaults standardUserDefaults] objectForKey:@"cookies"];

    NSMutableString *cookieStringToSet = (cookiesSaved ? [NSMutableString stringWithString:cookiesSaved] : [NSMutableString new]);

    NSArray *cookiesToSet = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:nsurl];
    for (NSHTTPCookie *cookie in cookiesToSet) {

        if ([cookieStringToSet rangeOfString:cookie.name].location == NSNotFound)
        {
            [cookieStringToSet appendFormat:@"%@=%@;", cookie.name, cookie.value];
        }
    }

    [[NSUserDefaults standardUserDefaults] setObject:cookieStringToSet forKey:@"cookies"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    [webview loadRequest:nsrequest];

    webview.scrollView.bounces = NO;

    [self.view addSubview:webview];
    [self.view bringSubviewToFront:webview];
}
