How to handle Push on App not running state?

问题:

Is it possible to open the iOS App based on push notification content? I believe it's not possible. Is there any other way around? I believe we can go with the widget in iOS10, right? Please suggest some good solution?

Thanks!

Whenever your payload has content-available:1 your app will get called in the backgroundstate as soon as it arrives and will call application(_:didReceiveRemoteNotification:fetchCompletionHandler:). It will only not get called if the user killed the app manually. (This doesn't launch your app. It requires your app to be launched though)

Having that said if your app was terminated (by user) but the user taps on the notitication then your app is launched from didFinishLaunching...delegate method.

Whenever the user taps on push notification the application launches from not running state to running state the in AppDelegate func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

}
in this function you can check application is launch from push or application icon 

var notification: [AnyHashable: Any]? = (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as? [AnyHashable: Any])
if notification != nil {
    print("app received notification from remote\(notification)")
    application(application, didReceiveRemoteNotification: notification)
}
else {
    print("app did not receive notification")
}

Yes we can not open ios applications on push notifications but we can wake up the app on push notifications. Its called VOIP notification. You can have more info regarding this from below link https://github.com/hasyapanchasara/PushKit_SilentPushNotification
