检测React Native iOS应用程序是否通过推送通知打开

>应用程序已完全终止(例如重新启动手机,或双击家中,并从后台运行的应用程序列表中将其滑动),并由用户点击推送通知启动.这可以通过React.PushNotificationIOS.getInitialNotification方法检测(和通知的数据).
>该应用已被暂停,并被用户点击推送通知再次激活.只要like in a native app,你可以知道这是发生的,因为iOS在开启时将启动的通知传递给你的应用程序(即使是旧的通知),并且当您的应用程序处于UIApplicationStateInactive状态(或“后台”状态,作为React Native的AppStateIOS类调用它).

处理这两种情况的代码(您可以将其放在index.ios.js或应用程序启动时运行的其他位置)：

import React from 'react-native';
var {PushNotificationIOS,AppStateIOS} = React;

function appOpenedByNotificationTap(notification) {
  // This is your handler. The tapped notification gets passed in here.
  // Do whatever you like with it.
  console.log(notification);
}

PushNotificationIOS.getInitialNotification().then(function (notification) {
  if (notification != null) {
    appOpenedByNotificationTap(notification);
  }
});

let backgroundNotification;

PushNotificationIOS.addEventListener('notification',function (notification) {
  if (React.AppStateIOS.currentState === 'background') {
    backgroundNotification = notification;
  }
});

React.AppStateIOS.addEventListener('change',function (new_state) {
  if (new_state === 'active' && backgroundNotification != null) {
    appOpenedByNotificationTap(backgroundNotification);
    backgroundNotification = null;
  }
});
