Eureka MultivaluedSection 添加 NSRangeException

Question

需要任何类型的特殊设置才能使 MultivaluedSection Add 功能在 Eureka 中工作？

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，这让我觉得我需要一些额外的设置，也许吧？

异常：

'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 覆盖了 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

Answer 2

关于OP，我也有同样的错误。在我的例子中，这是因为我将 FormViewController() 错误地嵌入到另一个视图控制器中。

我的解决方案是将其添加为 childViewController (see Eureka Issue 1045). In short, childViewControllers receive appearance & rotation events from parent VC (viewWillAppear etc) What does addChildViewController actually do?。

我的工作示例代码 (swift 4.2):

class MyViewController: UIViewController {

  var tempForm:FormViewController!

  override func viewDidLoad() {
    super.viewDidLoad()

    tempTemp = FormViewController()
    self.addChild(tempForm) 

    self.setupTempFormSections()
  }
  private func setupTempFormSections(){
     tempForm.form +++ Section(...)
  }
  ...
}
