Question

I have a UIWebView that navigates to a webpage using Basic Authorisation using this code

NSString *authValue = [NSString stringWithFormat:@"Basic %@", AFBase64EncodedStringFromString(basicAuthCredentials)];
    [urlRequest setValue:authValue forHTTPHeaderField:@"Authorization"];

Now when a link is clicked, the webView’s shouldStartLoadWithRequest is fired but the page isn’t loaded because the next page also needs the authorisation.

Is there a way to automatically add the Auth to the links clicked?

Thanks

How to properly create a new request in shouldStartLoad

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    BOOL shouldNavigate = NO;
    NSString *existingAuthValue = [request valueForHTTPHeaderField:@"Authorization"];
    if (existingAuthValue == nil)
    {
        NSString *authValue = [NSString stringWithFormat:@"Basic %@", AFBase64EncodedStringFromString(basicAuthCredentials)];
        [request setValue:authValue forHTTPHeaderField:@"Authorization"];
        NSMutableURLRequest *newRequest = [NSMutableURLRequest requestWithURL:request.URL];
        //Append any other info from the old request
        [webView performSelector:@selector(loadRequest:) withObject:newRequest afterDelay:0];
    }
    else
    {
        shouldNavigate = YES;
    }
    return shouldNavigate;
}

EDIT: Sorry, I wasn’t taking into account that NSURLRequest != NSMutableURLRequest. I’ll update the code.
