以NSException类型的未捕获异常终止？ ＆＃39; NSInternalInconsistencyException＆＃39;

Question

今天我运行的代码到目前为止还没有任何错误。每当有人点击底部的中间选项卡时，应用程序就会完全崩溃，但所有其他选项卡都能正常运行。这是调用堆栈：

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

我已经尝试寻找此错误的解决方案并检查故事板，但发现什么都不合适。关于修复的任何想法？

Answer 1

UITableViewController需要一个连接到它的view属性的UITableView。 还要确保委托和数据源已正确连接。

Answer 2

如果使用xib，请确保UITableView连接到fileOwner.tableView属性。 您可能使用xib文件来创建界面。
