在视图控制器之间切换时发生崩溃错误

Question

在视图控制器之间切换时出现错误。 使用情节提要通过segues进行切换。 有趣的是，如果我从ViewController A切换到B，然后又快速返回，则一切正常。 如果我从ViewController A切换到B，然后等待20秒，然后尝试切换回ViewController A，则我的应用程序因以下错误而崩溃：

'NSInternalInconsistencyException'，原因：'无法在名称为'2-view-3'且目录为'MainStoryboard_iPhone.storyboardc'的捆绑软件：'NSBundle（loaded）'中加载NIB”

要添加的两件事1.我正在使用没有nib或xib文件的情节提要2.我有MainStoryboard_iPhone.storyboard文件（它在错误消息中显示的末尾没有'c'）。

任何帮助表示赞赏。 这是完整的错误输出：

确保您在以下方法中加载任何与视图相关的内容，例如self.tableView ，这会导致不一致。

-(id)initWithCoder:(NSCoder *)aDecoder
