Try to use sharedCredentialStorage for all domains you need to authenticate.

Here is working sample for UIWebView it was tested against Windows IIS having only BasicAuthentication enabled

This is how to add your site credentials:

<pre><code>NSString* login = @"MYDOMAIN\\myname";
NSURLCredential *credential = [NSURLCredential credentialWithUser:login
 password:@"mypassword"
 persistence:NSURLCredentialPersistenceForSession];

NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
 initWithHost:@"myhost"
 port:80
 protocol:@"http"
 realm:@"myhost" // check your web site settigns or log messages of didReceiveAuthenticationChallenge
 authenticationMethod:NSURLAuthenticationMethodDefault];

[[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:credential
 forProtectionSpace:protectionSpace];
[protectionSpace release];
</code></pre>

Edit: same code in Swift 4

<pre><code>let login = "MYDOMAIN\\myname"
let credential = URLCredential(user:login, password:"mypassword", persistence:.forSession)
let protectionSpace = URLProtectionSpace(host:"myhost", port:80, protocol:"http", realm:"myhost", authenticationMethod:NSURLAuthenticationMethodDefault)
URLCredentialStorage.shared.setDefaultCredential(credential, for:protectionSpace)
</code></pre>

Your webView is supposed to work now, if it does not work use next code to debug, especially check log messages of didReceiveAuthenticationChallenge. 

<pre><code> #import "TheSplitAppDelegate.h"
 #import "RootViewController.h"

 @implementation TheSplitAppDelegate

 @synthesize window = _window;

 {
 // Override point for customization after application launch.
 // Add the split view controller's view to the window and display.
 self.window.rootViewController = self.splitViewController;
 [self.window makeKeyAndVisible];

The final solution for WebView authentication was based on custom protocol implementation. All protocols registered as a stack, so if you redefine HTTP protocol it would intercept all requests coming from webView, so you have to check attributes assotiated with incoming request and repack it into new request and send it again via your own connection. Since you are in stack, your request immidiatly comes to you again and you have to ignore it. So it goes down protocol stack to real HTTP protocol implementation, since your request is not athenticated you'll get authenticaiton request. And after authenticaiton you'll get a real response from server, so you repack response and reply to original request received from webView and that's it. 

Don;t try to create new requests or responses bodies, you have to just resend them. The final code would be aproximetly 30-40 lines of code and it is quite simple, but requires a lot of debuging and tetsing.

Unfortunatlly I cannot provide code here, since I am assigned to different project already, I just wanted to say that my post is wrong way, it stucks when user changes password.

I've just implemented this by setting basic auth credentials using an <code>NSMutableURLRequest</code> for the <code>UIWebView</code>. This also avoids the round trip incurred when implementing <code>sharedCredentialStorage</code> (of course there are tradeoffs involved).

Solution:

<pre><code> NSString *url = @"http://www.my-url-which-requires-basic-auth.io"
 NSString *authStr = [NSString stringWithFormat:@"%@:%@", username, password];
 NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
 NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodedString]];
 NSMutableURLRequest *mutableRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
 [mutableRequest setValue:authValue forHTTPHeaderField:@"Authorization"];
 NSURLRequest *request = [mutableRequest copy];
 NSURLRequest *request = [NSURLRequest basicAuthHTTPURLRequestForUrl:url];
 [self.webView loadRequest:request];
</code></pre>

You can grab the NSData+Base64 category which implements the <code>base64EncodedString</code> for NSData from <a href="http://www.cocoawithlove.com/2009/06/base64-encoding-options-on-mac-and.html" rel="nofollow noreferrer">Matt Gallagher's page</a> (it was at the bottom of the blog post when I downloaded it)

I would like to support HTTP Basic Authentication in my UIWebView. 

At the moment, I am canceling requests in 

<code>webView:shouldStartLoadWithRequest:navigationType:</code> then handle them in my own NSURLConnectionDelegate to check for and provide credentials if needed. I then use <code>loadData:MIMEType:textEncodingName:baseURL:</code> to present HTML in the web view. That works fine for any URLs that are passed to the delegate.

My problem is that the delegate is never called for embedded elements, like images, JavaScript or CSS files. So if I have an HTML page which references an image which is protected with basic authentication, that image cannot be loaded properly. Additionally, <code>webView:didFinishLoad:</code> is never called, because the web view could not fully load the page. 

I have checked that case with Terra, a third-party browser available on the App Store, and it can fully cope with that situation. I think it would be possible to solve this by providing my own NSURLProtocol, but that seems too complicated. What am I missing?
