react native弹窗封装
creat_bug 人气:0上图
仿苹果弹窗组件(android+ios均可用)
以上效果均基于本文的弹窗组件,后续将会介绍上面的组件,也可基于改组件定制更多组件
安装依赖 yarn add react-native-root-siblings 或者 npm install react-native-root-siblings --save
主要代码
显示弹窗
export const showModal = (component) => { sibling = new RootSiblings(component); };
销毁弹窗
export const destroySibling = (component) => sibling && sibling.destroy()
更新弹窗
export const update = (index, component) => sibling && sibling.update(<View>{component}</View>)
完整代码
多弹窗管理不涉及,暂时介绍单个弹窗,感兴趣的可以自己试试,将sibling改为数组;
//ShowModal.js import React from 'react'; import {View} from 'react-native'; import RootSiblings from 'react-native-root-siblings'; //全局弹框组件 let sibling = null; export const showModal = (component) => { sibling = new RootSiblings(component); }; export const destroySibling = (component) => sibling && sibling.destroy() export const update = (index, component) => sibling && sibling.update(<View>{component}</View>)
使用示例—>淡入背景
组件 ModalBg.js
import React from 'react'; import {Animated, InteractionManager, Easing, TouchableOpacity} from 'react-native'; import {getScreenHeight, getScreenWidth} from '../../utils/util'; import {destroyLastSibling} from '../showModal/ShowModal'; export default class ModalBg extends React.Component { animated = new Animated.Value(0); isShow = false; componentDidMount(): void { InteractionManager.runAfterInteractions(() => { this.handleAni(); }); } componentWillUnmount(): void { InteractionManager.runAfterInteractions(() => { this.handleAni(); }); } handleAni = () => { Animated.timing(this.animated, { toValue: this.isShow ? 0 : 1, duration: 250, easing: Easing.ease }).start(() => this.isShow = !this.isShow); }; render() { const opct = this.animated.interpolate({ inputRange: [0, 1], outputRange: [0, 0.4] }); return <Animated.View style={{ position: 'absolute', width: getScreenWidth(), height: getScreenHeight(), backgroundColor: '#000', opacity: opct, zIndex: 10 }}><TouchableOpacity onPress={() => { destroyLastSibling(); }} style={{flex: 1}} /></Animated.View>; } }
调用
showModal(<ModalBg />);
