ios - Eureka MultivaluedSection 添加 NSRangeException

Question

使 MultivaluedSection Add 功能在 Eureka 中工作需要任何类型的特殊设置吗？

我已将示例项目中的代码复制到我的项目中，但没有添加行，而是出现异常。有趣的是，在示例项目中，一切似乎都运行良好，这让我觉得我可能需要某种额外的设置，对吗？

异常(exception):

'NSRangeException'，原因:'-[UITableView _contentOffsetForScrollingToRowAtIndexPath:atScrollPosition:usingPresentationValues:]:第 (1) 节的第 (1) 行超出范围 (1)。

uncaught exception 'NSRangeException', reason: '-[UITableView _contentOffsetForScrollingToRowAtIndexPath:atScrollPosition:usingPresentationValues:]: row (1) beyond bounds (1) for section (1).'

Answer 1

已解决。

我的自定义 ViewController 正在覆盖 override func viewWillAppear(_ animated: Bool)，但我忘记调用 super.viewWillAppear()。

事实证明这对 Eureka 正常工作至关重要
