您好，请问这个是什么问题导致的？Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'UICollectionView must be initialized with a non-nil layout parameter'
版本： 0.2.0
奔溃代码：

• (LTAdvancedManager *)managerView {
  if (_managerView == nil) {
  _managerView = [[LTAdvancedManager alloc] initWithFrame:CGRectMake(0, NavgationBarHeight, ScreenWidth, ScreenHeight-NavgationBarHeight-PortraitSafeAreaBottom) viewControllers:self.viewControllers titles:self.titles currentViewController:self layout:self.layout titleView:self.titleView headerViewHandle:^UIView * _Nonnull {

        return self.headView;
    }];
    
    /* 设置代理 监听滚动 */
    _managerView.delegate = self;
    
    /* 设置悬停位置 */
    // _managerView.hoverY = 64;
    
    /* 点击切换滚动过程动画 */
    // _managerView.isClickScrollAnimation = YES;
    
    /* 代码设置滚动到第几个位置 */
    // [_managerView scrollToIndexWithIndex:self.viewControllers.count - 1];
  

  }
  return _managerView;
  }
