    <p>Try to use sharedCredentialStorage for all domains you need to authenticate.</p> <p>Here is working sample for UIWebView it was tested against Windows IIS having only BasicAuthentication enabled</p> <p>This is how to add your site credentials:</p> <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> <p>Edit: same code in Swift 4</p> <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> <p>Your webView is supposed to work now, if it does not work use next code to debug, especially check log messages of didReceiveAuthenticationChallenge. </p> <pre><code> #import "TheSplitAppDelegate.h" #import "RootViewController.h" @implementation TheSplitAppDelegate @synthesize window = _window; @synthesize splitViewController = _splitViewController; @synthesize rootViewController = _rootViewController; @synthesize detailViewController = _detailViewController; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // 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]; NSLog(@"CONNECTION: Add credentials"); 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]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://myhost/index.html"] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:12 ]; NSLog(@"CONNECTION: Run request"); [[NSURLConnection alloc] initWithRequest:request delegate:self]; return YES; } - (void)applicationWillResignActive:(UIApplication *)application { } - (void)applicationDidEnterBackground:(UIApplication *)application { } - (void)applicationWillEnterForeground:(UIApplication *)application { } - (void)applicationDidBecomeActive:(UIApplication *)application { } - (void)applicationWillTerminate:(UIApplication *)application { } - (void)dealloc { [_window release]; [_splitViewController release]; [_rootViewController release]; [_detailViewController release]; [super dealloc]; } - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge; { NSLog(@"CONNECTION: got auth challange"); NSString* message = [NSString stringWithFormat:@"CONNECTION: cred cout = %i", [[[NSURLCredentialStorage sharedCredentialStorage] allCredentials] count]]; NSLog(message); NSLog([connection description]); NSLog([NSString stringWithFormat:@"CONNECTION: host = %@", [[challenge protectionSpace] host]]); NSLog([NSString stringWithFormat:@"CONNECTION: port = %i", [[challenge protectionSpace] port]]); NSLog([NSString stringWithFormat:@"CONNECTION: protocol = %@", [[challenge protectionSpace] protocol]]); NSLog([NSString stringWithFormat:@"CONNECTION: realm = %@", [[challenge protectionSpace] realm]]); NSLog([NSString stringWithFormat:@"CONNECTION: authenticationMethod = %@", [[challenge protectionSpace] authenticationMethod]]); } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{ // release the connection, and the data object [connection release]; // inform the user NSLog(@"CONNECTION: failed! Error - %@ %@", [error localizedDescription], [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]); } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response; { NSLog(@"CONNECTION: received response via nsurlconnection"); } - (BOOL)connectionShouldUseCredentialStorage:(NSURLConnection *)connection; { NSLog(@"CONNECTION: USE!"); return YES; } @end </code></pre> <p>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. </p> <p>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.</p> <p>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.</p>

    1. COdoes this happen automatically? Once authenticated against a host, it seems that it's not necessary to re-authenticate on subsequent requests.

    2. COI'm seeing the same behavior as Max. Once authenticated, I'm not being challenged to re-authenticate again. Something is being stored in my iOS simulator session I guess? I tried resetting the simulator, but still not being challenged. Strange.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
