我有一个ios应用程序，当我从服务器发送通知时，我在哪里发送远程通知我设置 content -available = 1 和 sound =＆＃34;＆＃34; < /强> 在IOS设备上我正在使用

应用程序了（didReceiveRemoteNotification：fetchCompletionHandler：）

我在后台看到该应用程序达到此方法但是当应用程序关闭时，此方法未被调用但在应用程序关闭时未被调用

应用程序了（didReceiveRemoteNotification：fetchCompletionHandler：）

此方法中的处理程序是

let userInfoDic = userInfo as NSDictionary as? [String: Any] let cato = userInfoDic?["cato"] as? String if cato == "message" { let state: UIApplicationState = UIApplication.shared.applicationState if state == .active{ print("Application is Active Socket IO will Handle This") }else{ let apnMessage = userInfoDic?["apnMessage"] as? [String: Any] if (apnMessage == nil){ print("Error Fetching Message") }else{ let count = UserDefaults.standard.integer(forKey:"TotalUnredMessage") DispatchQueue.main.async { UIApplication.shared.applicationIconBadgeNumber = count + 1 } UserDefaults.standard.set(count, forKey: "TotalUnredMessage") } }

那么，即使关闭应用程序，我应该更改此方法的运行

didReceiveRemoteNotification 方法不会调用。

但您可以查看 launchOptions ，了解应用程序是否已通知appnlegate中的 didFinishWithLaunchOptions 方法通知，并相应地执行您的任务。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {

     if launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] != nil {
    // Do your task here
    }

}
