this class is not key value coding-compliant for t

用xib自定义UITableviewCell时遇到一个崩溃，最后的堆栈跟这篇文章有点类似:

)

terminate called after throwing an instance of 'NSException'

在Xcode中还显示了这样的关键一句错误信息：

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ 
setValue:forUndefinedKey:]: this class is not key value coding-compliant
 for the keyaRemovedView.'“

定位到的错误原因为将自定义的CustomTableviewCell的File's Owner的Class设置为了CustomTableviewCell，而实际上不用设置，只需要将TableView Cell的class设置为它即可。因为自己将cell重命名了，沿用了UIViewController的习惯修改了File's Owner的Class设置，惯性思维啊
