Does it support Sync. process ? like calling a function that return a value from the service response and waiting the response to come back

• (BOOL)checkUserExistence{
  NSInteger callID;

  _jsonRPCService =[[DSJSONRPC alloc] initWithServiceEndpoint:[NSURL URLWithString:@"http://serv.m-diet.com/Persons.ashx"]];

  DSJSONRPCCompletionHandler completionHandler = ^(NSString *methodName, NSInteger callId, id methodResult, DSJSONRPCError *methodError, NSError *internalError) {
  if (methodError) {
  NSLog(@"\nMethod %@(%i) returned an error: %@\n\n", methodName, callId, methodError);
  return NO;
  }
  else if (internalError) {
  NSLog(@"\nMethod %@(%i) couldn't be sent with error: %@\n\n", methodName, callId, internalError);
  return NO;
  }
  else {
  NSLog(@"\nMethod %@(%i) completed with result: %@\n\n", methodName, callId, methodResult);
  NSMutableDictionary *responceDictionary = (NSMutableDictionary *)methodResult;
  return [[responceDictionary objectForKey:@"result"]boolValue];
  }
  };

  callID = [_jsonRPCService callMethod:@"CheckPersonID" withParameters:@{ @"PersonID" : @"[email protected]"} onCompletion:completionHandler];
  }

The README.md file says "Version 1.1.0 of Demiurgic JSON-RPC now has support for ARC." However, JSONKit.m lines 139-141 have this:

if __has_feature(objc_arc)

error JSONKit does not support Objective-C Automatic Reference Counting (ARC)

endif

It seems that ARC support is still lacking with 1.1.0. As I downloaded 1.1.0 and it does not build without the compiler no-arc compiler flag.

I don't see any licensing information, could you add it? Preferably MIT, assuming this is meant to be free and open source.

Nice project, btw. :)
