【问题描述】：

我目前正在开发自定义键盘 当我尝试在新窗口中组合 textDocumentProxy 时遇到问题

所以添加了表情符号键盘按钮 我通过页面添加了两个表情符号按钮现在我的问题是如何合并 textDocumentProxy 另一个窗口或它们之间的链接减弱甚至可以输入表情符号

我尝试输入任何内容，而不仅仅是表情符号

【问题讨论】：

所以您希望无法在自定义键盘中设置视图中的表情符号按钮？

是的，你能帮帮我吗？对不起，我可能无法很好地解释自己，但我很高兴将源代码发送给您，那么如何更好地理解我

是的，当用户启用表情符号按钮时，您可以将更改存储到NSUserDefaults。

我给你发了一封感谢信

【参考方案1】：

您需要根据您的要求将许多内容更改到您的项目中，例如您可以通过隐藏该 tableView 并在其上添加一个 UIView 来使用该设置视图，然后您可以将表情符号添加到该视图中，并且当用户单击设置按钮时键盘您可以隐藏您的表情符号视图并显示表格视图，但是当用户想要键入不需要隐藏任何内容的微笑时，只需显示您的表情符号视图。

HERE 是您更新的项目。
