Sync Process

[oxxy]

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" : @"sam@am.com"} onCompletion:completionHandler];
  }

The API does not support synchronous communication. However, you should be able to get that behavior using dispatch semaphores.
