对不起，伙计们，又是老我了。我正在联系，因为我需要第二个表视图的帮助，我想在另一个视图控制器中实现。我基本上从另一个实际工作的tableView控制器复制了此代码。所以我不确定我在这里搞砸了哪里，但我真的很感激你的帮助。

cell.msgContent.text = messageArray[indexPath.row]

return cell

您正在实现 UITableViewDataSource，但没有实现它是必需的方法。
func tableView(UITableView， cellForRowAt： IndexPath(
函数数章节(在： UITableView(
实现这两个，不符合协议的错误应该消失。
