How to handle NSURLAuthenticationChallenge in iOS7 - web-services

Question

I want to post something to a web service which has SSL problem.
I used following methods:
NSURLConnection * urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
It should immediately start sending data to which has been set in the request;
But Service has security problem and it doesn't work properly. However I want to send data and want to ignore security problem; So I used following methods of NSURLConnectionDelegate:
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
But they has been deprecated. How can I handle security problem and tell to pass data to web service without considering it?

Answer 1

you should use willSendRequestForAuthenticationChallenge like this.
- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
self.challenge = challenge;
[self askUserAcceptSSLError];
}
- (void)askUserAcceptSSLError
{
// Ask user like UIAlertView or so.
// Put these responses in UIAlertView delegate ...
// If User accepts (or force this if you want ignore SSL certificate errors):
[[self.challenge sender]
useCredential:[NSURLCredential credentialForTrust:self.challenge.protectionSpace.serverTrust]
forAuthenticationChallenge:self.challenge];
[[self.challenge sender] continueWithoutCredentialForAuthenticationChallenge:self.challenge];
// If User deny request:
[[self.challenge sender] cancelAuthenticationChallenge:self.challenge];
}
