Ios 以NSException Xcode类型的未捕获异常终止

我在学习教程时遇到了一个问题。它不起作用。有人能帮我纠正这个错误吗？本教程使用Swift 4、iOS 11和Xcode 9，但我使用iOS 12和Xcode 10.1。这是问题的根源吗？因为我只是正确地遵循了教程

以下是错误消息：

libc++abi.dylib: terminating with uncaught exception of type NSException

您可以在我的github repo上找到我的源代码。

您在故事板中将单元格标识符定义为

PlayersCell

。

---

将其更改为

PlayerCell

请仔细阅读错误消息。最重要的部分是

无法将标识符为PlayerCell的单元格出列

以及

nsassertionhandlefailureinmethod

行之前的行，该行指示错误发生的位置：

0x0000000119EC5B1-[UITableView\u dequeueReusableCellWithIdentifier:forIndexPath:usingPresentationValues:+868

---

这意味着Interface Builder中表格视图单元格的重用标识符未设置或与

cellForRow

中指定的标识符不匹配。在您的情况下，这是一个简单的输入错误。

不要发布指向GitHub repo的链接，在您的问题中发布
