I can't take any credit for this, but this one I found worked really well for my needs. shouldAllowSelfSignedCert is my BOOL variable. Just add to your NSURLConnection delegate and you should be rockin for a quick bypass on a per connection basis.

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)space {
     if([[space authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust]) {
          if(shouldAllowSelfSignedCert) {
               return YES; // Self-signed cert will be accepted
          } else {
               return NO;  // Self-signed cert will be rejected
          }
          // Note: it doesn't seem to matter what you return for a proper SSL cert
          //       only self-signed certs
     }
     // If no other authentication is required, return NO for everything else
     // Otherwise maybe YES for NSURLAuthenticationMethodDefault and etc.
     return NO;
}
