didReceiveRemoteNotificationメソッドを実装しました。動作し、渡された通知データとともにViewControllerを表示します。これは、アプリがすでにフォアグラウンドにある場合、またはアプリがバックグラウンドで実行されている場合にのみ機能します。ただし、アプリが実行されておらず、ユーザーが通知をクリックすると、アプリは起動しますが、通知が受信されていないように見えます。通知はテキストファイルに書き込まれず、ビューコントローラはプッシュされません。

        {

        [self.mainNavController setViewControllers:vcs animated:YES];

    }
            // app was just brought from background to foreground


}

誰かが私がこの問題を解決するのを手伝ってくれませんか？didFinishLaunchingWithOptionsが完了すると、ブール値doneはtrueに設定されます。アプリがまったく実行されていないときに通知が押された場合に、notificationviewcontrollerを開いて通知を表示したいだけです。

次のようなものをコードに追加する必要があります。

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
    *)launchOptions {

        NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];

        //Accept push notification when app is not open
        if (remoteNotif) {      
            [self handleRemoteNotification:application userInfo:remoteNotif];
            return YES;
        }

        return YES;
    }

ロジックをdidReceiveRemoteNotificationからいくつかの一般的な関数に移動し、両方の場所からその関数を呼び出すことができます。これは、ユーザーが通知をタップしてアプリを開いた場合にのみ機能します。ユーザーがアプリアイコンをタップしてアプリを開くと、通知データはアプリに届きません。

スウィフトコード

let remoteNotif: AnyObject? = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey]

            //Accept push notification when app is not open
            if ((remoteNotif) != nil) {

                self.handleRemoteNotification(remoteNotif!)
            }


func handleRemoteNotification(remoteNotif: AnyObject?){
//handle your notification here
}

@エランありがとう:)
