SIGSEGV SEGV_ACCERR错误 - 没有方法从应用程序引用

Question

没有方法从我的应用程序在此崩溃报告中引用，我一直无法重现它。我的一些用户正在发生同样的崩溃。我找不到任何带有scrollview或任何使用弹簧的地方的tableview单元格。这次事故是从哪里来的？

Answer 1

这是我所看到的查看崩溃报告：

1. 的崩溃是贝SIGSEGV在objc_msgSend引起的。这意味着应用程序正在尝试将消息发送给无效的对象。这意味着您的应用（某处）至少有一个内存问题。

2. 它看起来像问题尝试使用滑动删除手势删除行中的tableView发生时，看到-[UITableView _endSwipeToDeleteRowDidDelete:]没有显示在堆栈跟踪和附加提示上述像-[UITableViewCell _animateSwipeCancelation]，-[UITableViewCell _updateViewsForDeleteButton]。

因此，它可能是值得一试检查应用中的所有表视图这种使用情况。

另外使用Xcode的Analyze功能，并修复它显示的所有警告，并尝试使用Enable Zombie Objects集合运行您的应用程序。有很多网站，并在这里解释如何做到这一点。
