How to set my web view loaded with already login user -iPhone
提问by iOS dev
In my app iam using web view with URL:@"http://www.gmail.com/".
在我的应用程序中，我使用带有 URL:@"http://www.gmail.com/" 的 web 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]; }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]; }
当我单击主页/主页中的按钮时加载了此 Web 视图
(IBAction)webClick:(id)sender { MailViewController *mail = [[MailViewController alloc]initWithNibName:@"MailViewController" bundle:nil]; [self.navigationController pushViewController:mail animated:YES]; }然后加载了 web 视图，我在邮件视图中使用了像这样的代码：
-(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.
在这里，gmail 打开了登录页面。我们需要输入用户名和密码。
What i want is,
我想要的是，
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.
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，那么显示一个警告，请登录。
How to do it?
怎么做？
Please help me. Thanks in advance.
请帮我。提前致谢。

First of all, I think the URL you should be loading is http://mail.google.com/mail
首先，我认为你应该加载的 URL 是 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:
除此之外，由于 UIWebView 不会在应用程序运行之间保存 cookie，因此您无法获得正常的 gmail 行为，您应该尝试使用以下方法来保存它们：
- (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:
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];
}
}
