ionic4 打开appstore 跳转第三方app

1. 需要用到的插件

(1)检测 APP 是否安装的插件

ionic cordova plugin add cordova-plugin-appavailability --save
npm install --save @ionic-native/app-availability

(2)调用手机内部APP的插件

ionic cordova plugin add com.lampa.startapp

https://github.com/lampaa/com.lampa.startapp

引入到 app.module.ts

import { AppAvailability } from '@ionic-native/app-availability/ngx';
providers: [AppAvailability
]

引入到 业务页面

import { AppAvailability } from '@ionic-native/appavailability/ngx';
declare let startApp: any;scheme = '';

if (this.platform.is('ios')) {this.appName = 'dangdang://';      /* Scheme URL */this.plat = 'ios';} else if (this.platform.is('android')) {this.appName = 'com.dangdang.buy2';     /* 安卓包名 */this.plat = 'and';}this.scheme = 'itms-apps://itunes.apple.com/app/id*********';  /* appstore Scheme URL     *********代表ios appid */this.appAvailability.check(this.appName).then((yes: boolean) => {   /* 已安装，打开高德地图 */this.startApp(uri)},(no: boolean) => {/* 未安装，请编写提示代码或跳转下载 */});startApp(uri) {let sApp;if (this.platform.is('ios')) {sApp = startApp.set(encodeURI(uri));} else {sApp = startApp.set({ /* params */"action": "ACTION_VIEW","category": "CATEGORY_DEFAULT","type": "text/css","package": this.appName,"uri": uri,"flags": ["FLAG_ACTIVITY_CLEAR_TOP", "FLAG_ACTIVITY_CLEAR_TASK"],"intentstart": "startActivity"});}sApp.start(function () { /* success */console.log("OK");}, function (error) { /* fail */console.log(error);this.utilService.showToast(this.toast, '调起失败');});}

AppStore获取app版本号

APPID

https://itunes.apple.com/cn/lookup?id=xxxx

bundleId

https://itunes.apple.com/cn/lookup?bundleId=xxxx

IOS打开第三方app报错anOpenURL: failed for URL: "weibo://" - error: "This app is not allowed to query for scheme dangdang",解决方法见下图

在info.list文件里的LSApplicationQueriesSchemes里，增加对应配置。如 wechat
