How do I pass login information to a website from

问题:

I want to open some website in my iphone app using UIWebView. The website requires username and password and I have these username and password.

I was wondering is there anyway I can open the website in my UIWebView without any login screen? I mean as I already have the username and password, can I use this information to log in to website automatically and show the required necessary page onto my UIWebView iphone app.

I just want to get rid of logging to website as users have already entered the login information when they open the app. Thats redundant.

Any help is greatly appreciated.

Thanks.

I have discovered way to solve this in a Objective-C way. We can use NSURLConnection to post the form.

Code:

 NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://mobile.twitter.com/session"]
                                                 cachePolicy:NSURLRequestUseProtocolCachePolicy                                              timeoutInterval:60.0];

[theRequest setHTTPMethod:@"POST"];

NSString *postString = [NSString stringWithFormat:@"authenticity_token=%@&username=%@&password=%@",@"9b670208fd22850ec791",@"urUsername",@"urPWD"];
[theRequest setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];

// create the connection with the request
// and start loading the data
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
    // Create the NSMutableData to hold the received data.
    // receivedData is an instance variable declared elsewhere.
    receivedData = [[NSMutableData data] retain];
} else {
    // Inform the user that the connection failed.
}

Ask me if you need more information.

If you have developed the website yourself, why not create another entry point where you pass the username/password securely, using ssl, to the page? If SSL is not an options, you could generate a token within the app and pass this. No need for username/password to be passed at all then.
