Question

此崩溃报告中没有引用我的应用程序的方法，但我无法重现它。我的几个用户遇到了同样的崩溃。我找不到任何带滚动视图的tableview单元格或任何使用弹簧的地方。这次崩溃可能来自哪里？

Answer 1

这是我看到的崩溃报告：

崩溃是SIGSEGV中的objc_msgSend造成的。这意味着应用程序正在尝试向无效的对象发送消息。这意味着您的应用程序（某处）至少存在一个内存问题。
尝试使用滑动删除手势删除tableView中的行时会出现问题，请参阅显示在堆栈跟踪中的-[UITableView _endSwipeToDeleteRowDidDelete:]以及上面的其他提示，如-[UITableViewCell _animateSwipeCancelation] ，-[UITableViewCell _updateViewsForDeleteButton]。

因此，在应用程序的所有表视图中检查此用例可能值得一试。

此外，使用Xcode的Analyze功能并修复其显示的所有警告，并尝试使用Enable Zombie Objects设置运行您的应用。有很多网站，也在这里回答SO解释如何做到这一点。
