从本地通知启动关闭的 iOS 应用程序 [英] Launch Closed iOS App From Local Notification

问题描述

当我的 iOS 应用程序在后台运行时，它响应良好

When my iOS application is running in the background it responds fine to

 - (void)application:(UIApplication *)application didReceiveLocalNotification:
    (UILocalNotification *)notification

但是当应用程序关闭时它会崩溃并给出SIGKILL错误.

but when the application is closed it crashes and gives a SIGKILL error.

如果在收到通知时关闭了应用程序中的方法，我该如何运行?

How can I run a method within the app if it is closed when the notification is received?

推荐答案

当收到本地通知时，您无法在应用中运行方法.通知可以提供警报、图标徽章编号和声音(<30 秒)的任意组合.

You can't run a method in the app when a local notification is received. The notification can provide any combination of an alert, icon badge number, and a sound (<30 secs).

当一个方法再次进入前台时，您可以通过通知或其他方式运行它.

You can run a method when it comes into the foreground again either through the notification or through other means.

当应用处于后台时，它将在恢复之前调用 applicationWillEnterForeground:.您可以覆盖此方法以处理通知后所需的任何内容.您可以覆盖 applicationDidEnterBackground: 以确定您的应用何时真正进入后台.

When the app is in the background it will call applicationWillEnterForeground: prior to resuming. You can override this method to handle anything needed after the notification. You can override applicationDidEnterBackground: to determine when your app actually enters the background.

方法 application:didReceiveLocalNotification: 当应用收到通知但在前台时调用.应用在前台时不会触发警报、图标徽章编号和声音.

Method application:didReceiveLocalNotification: is called when the app receives a notification but is in the foreground. The alert, icon badge number, and sound will not be triggered when the app is in the foreground.
