iPhone https联接备忘

There is a supported API for accomplishing this! Add something like this to your NSURLConnection delegate:

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

Note that connection:didReceiveAuthenticationChallenge: can send its message to challenge.sender (much) later, after presenting a dialog box to the user if necessary, etc.
