'NSUnknownKeyException': this class is not key value coding-compliant for the key
提问by MortadaAK
I got this message:
我收到了这条消息：
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<FirstViewController 0x601b610> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key newCell.'
How do I solve it?
我该如何解决？

That is generally due to deleting an IB object but forgetting to delete it's links.
这通常是由于删除了 IB 对象但忘记删除它的链接。
IE deleting a UIScrollView but forgetting to delete how it used to link into UIView through an IBOutlet.
IE 删除 UIScrollView 但忘记删除它如何通过 IBOutlet 链接到 UIView。

In case that helps someone else, after checking and updating all your links between the views and the matching IBOulet, Cleaning you project can sometimes fix this issue.
如果对其他人有帮助，在检查并更新视图与匹配 IBoulet 之间的所有链接后，清理您的项目有时可以解决此问题。
