如何设置我的 Web 视图已加载已登录用户 -iPhone

问题描述

在我的应用程序中，我使用带有 URL 的 Web 视图:@http://www.gmail.com/".

• 当我点击主页/主页中的按钮时，该网页视图已加载

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

• 然后加载 web 视图，我在邮件视图中使用了这样的代码:

  -(void)viewDidLoad{[超级视图DidLoad];NSString *urlAddress = @"http://www.gmail.com/";NSURL *url = [NSURL URLWithString:urlAddress];NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];[webView loadRequest:requestObj];}

这里的 gmail 打开了登录页面.我们需要输入用户名 &密码.

我想要的是，

• 如果我们已经通过 gmail 应用程序登录到我的帐户..

  加载的视图直接加载我的邮件，而不是登录页面.

• 如果我还没有登录，请在登录时显示警报.

怎么做?

请帮助我.提前致谢.

首先，我认为你应该加载的 URL 是 http://mail.google.com/mailp>

除此之外，由于 UIWebView 不会在应用程序运行之间保存 cookie，因此您没有获得正常的 gmail 行为，您应该尝试这样的方法来保存它们:

- (void)saveCookies{NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]];NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];[默认设置对象:cookiesData forKey:@cookies"]；[默认同步]；}

并使用以下方法将它们加载回来:

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

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

• 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];
  }
  

• 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];
  }
  

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

What i want is,

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

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

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

How to do it?

Please help me. Thanks in advance.

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

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];
}

and load them back using this:

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

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