ios - 我怎样才能制作表情符号或输入任何内容

Question

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

所以有添加表情符号键盘按钮 我通过添加两个表情符号按钮传递页面现在我的问题是如何将 textDocumentProxy 合并到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

我尝试输入任何东西，而不仅仅是表情符号

您需要根据您的要求将很多东西更改到您的项目中，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 View ，之后您可以将表情符号添加到该 View 中，当用户单击设置按钮时键盘你可以隐藏你的表情符号 View 并显示表格 View 但是当用户想要输入微笑时你不需要隐藏任何东西只需显示你的表情符号 View 。

HERE是您更新的项目。
