我收到致命异常： NSRangeException *** -[__NSArrayM objectAtIndex:]: 索引 0 超出空数组范围
但是没有调用removeObjectAtIndex，并且这种情况发生在不同的视图控制器中。我只是在寻找关于在哪里查看的想法，因为在第 3-5 行中，应用程序被赋予了控制权，但没有符号。
崩溃日志来自 Fabric/crashlytics，仅在应用程序发布后大约 30 天发生，但崩溃的实例或数量是相关的。

该应用程序有一个DetailViewController继承自BaseViewController.DetailViewController有DetailViewModel房产.
DetailViewController,BaseViewController并且DetailViewModel都是用Objective-C.我将Swift版本升级为Swift 4并添加了一个Swift扩展DetailViewModel.
@objc extension DetailViewModel {
func foo() {
let conclusionBlock: (() -> Void) = { [weak self] in
guard let strongSelf = self else { return }
strongSelf.viewController.reloadData()
}
let viewModel = OtherViewModel(conclusionBlock: conclusionBlock)
let otherViewController = OtherViewController.make(viewModel: viewModel)
let nav = UINavigationController(rootViewController: otherViewController)
nav.modalPresentationStyle = .fullScreen
viewController.present(nav, animated: true, completion: nil)
}
}
查看日志,func foo() …
