    copied!<p>I have an app that is production along with a development server that has a <strong>self signed certificate.</strong> </p> <p>I am attempting to test <code>NSURLSession</code> and background downloading but can't seem to get past <code>- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler</code></p> <p>When I use <code>NSURLConnection</code> I am able to bypass it using: </p> <pre><code>- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { NSLog(@"canAuthenticateAgainstProtectionSpace %@", [protectionSpace authenticationMethod]); return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { NSLog(@"didReceiveAuthenticationChallenge %@ %zd", [[challenge protectionSpace] authenticationMethod], (ssize_t) [challenge previousFailureCount]); [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; } </code></pre> <p>But I can't figure out how to get this to work with <code>NSURLSession</code> >:(</p> <p>This is what I have currently (that doesn't work): </p> <pre><code>- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler { NSLog(@"NSURLSession did receive challenge."); completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]); } </code></pre> <p>I also tried creating a category of <code>NSURLSession</code> that would allow any certificate for a host: </p> <pre><code>#import "NSURLRequest+IgnoreSSL.h" @implementation NSURLRequest (IgnoreSSL) + (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host { return YES; } + (void)setAllowsAnyHTTPSCertificate:(BOOL)allow forHost:(NSString*)host {} @end </code></pre> <p>Which also doesn't seem to help. </p> <hr> <p><strong>EDIT</strong></p> <p>I've updated this method to return: </p> <pre><code>- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler { //Creates credentials for logged in user (username/pass) NSURLCredential *cred = [[AuthController sharedController] userCredentials]; completionHandler(NSURLSessionAuthChallengeUseCredential, cred); } </code></pre> <p>Which still does nothing. </p>
