【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
