没看懂registerRXRProtocolClass里这么写的意思

• (void)_frd_setCount:(NSInteger)count forRegisteredClass:(Class)clazz
  {
  NSString *key = NSStringFromClass(clazz);
  NSMutableDictionary *mutDict = [sRegisteredClassCounter mutableCopy];
  if (key) {
  if (!mutDict) {
  mutDict = [NSMutableDictionary dictionary];
  }
  mutDict[key] = @(count);
  }
  }

+ (void)_frd_setCount:(NSInteger)count forRegisteredClass:(Class)clazz
{

  if (key) {
    if (!mutDict) {

    }

  }
}

@daydayfree bug 了吧？
少了

sRegisteredClassCounter = mutDict;

@bigyelow 对的，逻辑有问题
