React-Native是一种基于React框架的移动应用开发框架,它允许开发者使用JavaScript和React的语法来构建原生移动应用。React-Native的优势在于可以同时开发iOS和Android平台的应用,减少了开发和维护两个平台的工作量。 React-Native的全局状态(Global State)是指应用中可以被多个组件共享和访问的数据。它可以存储应用的全局状态...

在React native开发中,经常需要获取屏幕宽高设置布局,或者是取屏幕宽高百分比设置布局。 通常做法都是创建一个工具文件比如utils.js,然后在工具文件中提前把屏幕宽高取出来,再创建一个get方法来获取对应的值。如此我们在哪里使用就需要在哪里导入utils.js,再执行get方法获取对应的值。
For function components, import { useGlobal } from "reactn"; to harness the power of React Hooks! For class components, simply change import React from "react"; to import React from "reactn";, and your React class components will have global state built in! If you prefer class decorators...
使用React Native开发过程中,将本地存储的模块react-native-storage放入了全局中,期望使用chrome调试时,可以像网页调试一样直接在控制台调试api,这样比在应用程序中调试方便很多。 但是,在控制台中,GLOBAL是未定义的,更别提访问全局的变量了。经过查找资料,发现了问题所在。
