如果有人能解释为什么会发生这种情况，将不胜感激。

【问题讨论】：

我觉得跟键盘没关系，是不是后面还有什么执行的？
实际上没有执行任何其他操作，它所做的只是在您单击保存按钮时保存笔记。但是，您没有机会单击保存按钮。您单击文本字段并键入您想要的任何内容，然后单击右下角的按钮关闭键盘。当您这样做时，应用程序崩溃，但我不明白为什么会发生这种情况。很困惑
对json的一些操作？这就是您的错误所说的 - JSON 写入中的类型无效 (_SwiftValue)
老实说，我不是专业编码人员，所以我不明白为什么它说 JSON 存在错误，因为在我更新到 xCode 8 之前代码运行良好。我确实收到了另一个错误AppDelegate.swift - 它突出显示这行代码 class AppDelegate: UIResponder, UIApplicationDelegate { 不知道为什么。它声明了一个 Thread:1 信号 SIGABRT
更新“保存到笔记”代码的问题，您是否设置了“异常刹车点”？它停在哪里？

【解决方案1】：

错误是Invalid type in JSON write (_SwiftValue)，这意味着它无法在 JSON 中序列化您的对象。当您在对象中设置的要序列化的数据类型不受 JSON 支持时会发生这种情况，因此序列化程序失败。

查看 Apple 文档 here，了解可接受的类类型。

这可能是导致崩溃的原因

【解决方案3】：

为各个 UIViewcontroller 移除未引用的 IBOutlets 和 IBAction。

Select "View > Utilities > Show Connections Inspector"

在我的情况下，使用上述解决方案解决了这个异常。

【解决方案4】：

希望对您有所帮助。

它对我来说太棒了。像这样改变你的对象属性，

textView.autocorrectionType = UITextAutocorrectionTypeNo;
textView.spellCheckingType = UITextSpellCheckingTypeNo;
