如何使用已登录用户-iPhone设置我的Web视图 [英] How to set my web view loaded with already login user -iPhone

问题描述

在我的应用程序中使用带URL的Web视图：@http://www.gmail.com/。

In my app iam using web view with URL:@"http://www.gmail.com/".

• 当我点击主页/主页中的按钮时加载了这个网页视图

• This web view was loaded when i clicked a button in the main page / home page

(IBAction)webClick:(id)sender
 {
MailViewController *mail = [[MailViewController alloc]initWithNibName:@"MailViewController" bundle:nil];
[self.navigationController pushViewController:mail animated:YES];
}

然后加载了网页视图，我使用的代码很像这个在邮件视图中：

Then the web view was loaded, i used code like thin this in mail view:

-(void)viewDidLoad

{
    [super viewDidLoad];
    NSString *urlAddress = @"http://www.gmail.com/";
    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [webView loadRequest:requestObj];
}

这里打开了gmail登录页面。我们需要输入用户名&密码。

Here the gmail opened with login page. we need to enter username & password.

我想要的是，

• 如果我们已经通过gmail应用程序登录我的帐户..

• if we already login into my account through gmail application..

加载的视图直接挂载我的邮件，而不是登录页面。

The loaded view directly loades my mail, instead of login page.

如果我还没有进入，请在登录时显示提醒。

if i didn't already loged in, then show an alert as please login.

如何这样做？

请帮帮我。
提前致谢。

Please help me. Thanks in advance.

推荐答案

首先，我认为您应该加载的网址是 http://mail.google.com/mail

First of all, I think the URL you should be loading is http://mail.google.com/mail

除此之外，你没有获得正常的gmail行为，因为UIWebView确实如此不保存应用程序运行之间的cookie，你应该尝试这样的东西来保存它们：

Other than that, you're not getting normal gmail behavior because UIWebView does not save cookies between app runs, you should try something like this to save them:

- (void)saveCookies
{
    NSData         *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]];
    NSUserDefaults *defaults    = [NSUserDefaults standardUserDefaults];
    [defaults setObject: cookiesData forKey: @"cookies"];
    [defaults synchronize];
}

并使用此加载它们：

- (void)loadCookies
{
    NSArray             *cookies       = [NSKeyedUnarchiver unarchiveObjectWithData: [[NSUserDefaults standardUserDefaults] objectForKey: @"cookies"]];
    NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

    for (NSHTTPCookie *cookie in cookies)
    {
        [cookieStorage setCookie: cookie];
    }
}
