xCode -错误/崩溃时解散键盘

我有一个问题与我的xCode项目，由于未知的原因，它开始崩溃时，关闭或隐藏键盘一旦你完成打字。在新的xCode 8更新之前没有发生这种情况，我希望有人能在这里帮助我。

如果有人能解释一下为什么会这样，我将不胜感激。

错误是Invalid type in JSON write (_SwiftValue)，这意味着它不能在JSON中序列化您的对象。当JSON不支持在对象中设置的要序列化的数据类型时，就会发生这种情况，因此序列化器失败。

查看这里的Apple文档，查看可接受的类类型

这可能会导致崩溃

为各自的UIViewcontroller删除未引用的IBOutlets和IBAction。

Select "View > Utilities > Show Connections Inspector"

在我的情况下，这个异常解决使用上述解决方案。

希望能帮上忙。

这对我来说很好，漂亮。将对象属性更改为

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