初学者使用Swift和错误选择器

我正在构建一个简单的应用程序，它有一个带有3个选项的PickerView，这些选项应该链接到3个视图控制器，每个视图控制器分别命名为FirstViewController、SecondViewController和ThirdViewController。
但我得到了这个错误

> NSInvalidArgumentException', reason: 'Receiver (<Scroller.ViewController: 0x7ff7b5e0b670>) has no segue with identifier 'SecondSegue'

有人能帮我理解如何解决这个问题吗

---

我给赛格起名字了吗？它们的名称都相同-对吗？

看来您的

第二个
UIViewController
到第二个
UIViewController
的名称不正确

小心，它区分大小写，必须准确命名为
SecondSegue
。更改名称后，别忘了用返回键验证您的输入。
您必须将second view controller的segue标识符设置为SecondSegue
Hi Boober Bunz-Hmm我遗漏了一些东西，我无法停止您所说的内容。您能给我多一点帮助吗“它们的名称都相同-对吗？”不。根据您的代码，它们应该被命名为
FirstSegue
，
SecondSegue”和
ThirdSegue`。请阅读错误消息。这很清楚。
