[React Native][IOS] 如何通过通知打开应用程序时捕获事件
[React Native][IOS] How to catch the event when the app is opened by a notification
React Native 有一个 PushNotificationIOS 模块来获取通知数据并监听 notificaiton、register 等事件。我想在通过以下通知打开应用程序时捕获一个事件：PushNotificationIOS.addEventListener('notification_open', myhandler);。有办法吗？
你有两个选择。
1。使用 PushNotificationIOS
您可以在重要的时候调用 PushNotificationIOS.getInitialNotification();。例如，您可以在应用程序的 index.js 文件中调用此方法并决定要呈现的组件。来自 the docs:
This method returns a promise. If the app was launched by a push notification, this promise resolves to an object of type PushNotificationIOS. Otherwise, it resolves to null.
2。使用本机 iOS App Delegate
来自 the UIApplicationDelegate documentation:
For example, if your app was launched because of an incoming remote notification, you might want to reconfigure your user interface to display data related to that notification. For a list of possible reasons why your app might be launched, see Launch Options Keys.
如果您出于某种原因需要更早地了解，您可以查看本机 application(_:willFinishLaunchingWithOptions:) 和 application(_:didFinishLaunchingWithOptions:) 方法。请注意，这些方法是在 React Native 初始化之前调用的。这是大多数 React Native 应用不需要的更高级的用例。
