ios - HTTPS Service is not working

Question

I want to login by using web service.

My website is https based. I am using following tutorial.

http://agilewarrior.wordpress.com/2012/02/01/how-to-make-http-request-from-iphone-and-parse-json-result/ 

Following code is working fine.

responseData = [NSMutableData data];
NSURLRequest *request = [NSURLRequest requestWithURL:
                         [NSURL URLWithString:@"https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=AIzaSyAbgGH36jnyow0MbJNP4g6INkMXqgKFfHk"]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];

but my code is

responseData = [NSMutableData data];
NSURLRequest *request = [NSURLRequest requestWithURL:
                         [NSURL URLWithString:@"https:myurl/login?userId=username&password=111111"]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];

and it give error

Connection failed: Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be --My URL-- which could put your confidential information at risk." UserInfo=0xa294260 {NSErrorFailingURLStringKey=https://mywebsite/login?userId=username&password=111111, NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, NSErrorFailingURLKey=https://mywebsite/login?userId=username&password=111111, NSLocalizedDescription=The certificate for this server is invalid.

Answer 1

What's happening is that your certificate is not valid (in the point of view of your app). If you want to take the risk, you can add the following code.

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
NSArray * trustedHosts = @[@"your domain"];
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
    if ([trustedHosts containsObject:challenge.protectionSpace.host])
        [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];

[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}

So the certificate will be ignored. (remember to replace "your domain", with your domain.)
