通常，我们创建了自定义键盘，例如https://developer.apple.com/documentation/uikit/keyboards_and_input/creating_a_custom_keyboard，我们还需要将数据存储在异步存储中并获取。添加后它在android中完美运行，.addPackage(new AsyncStoragePackage())但在ios中不起作用。
模块如：
index.js
AppRegistry.registerComponent(RNFirebaseBackgroundMessage, () => HeadlessCheck);
////Registering module for Custom Keyboard
AppRegistry.registerComponent('RNKeyboard', () => Keyboard);
期望：将数据存储在异步存储中，并在键盘加载时访问。
这是扩展的文件结构：
这是 KeyboardViewController.h 文件
#import "React/RCTAsyncLocalStorage.h"
#import "RNCAsyncStorage.h"
@interface KeyboardViewController : UIInputViewController
@end
像这样的 KeyboardViewController.m 文件
