something wrong in function processMessage of Pomelo.m

[DeqingQu]

• (void)processMessage:(NSDictionary *)msg
  {
  id msgId = [msg objectForKey:@"id"];
  if (msgId && msgId > 0){
  NSString *key = [NSString stringWithFormat:@"%@", msgId];
  PomeloCallback callback = [_callbacks objectForKey:key];
  if (callback != nil) {
  callback([msg objectForKey:@"body"]);
  [_callbacks removeObjectForKey:key];
  }
  } else {
  NSMutableArray *callbacks = [_callbacks objectForKey:[msg objectForKey:@"route"]];
  if (callbacks != nil) {
  for (PomeloCallback cb in callbacks) {
  cb([msg objectForKey:@"body"]);
  }
  }
  }
  The param of cb should be [msg objectForKey:@"body"].
