Accessing push payload if app is inactive

问题

I have a push notification, and when app receives it, I call the following

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    if userInfo["t"] as! String == "rqst"  {

        print("type is help request")

        if let token = NSUserDefaults.standardUserDefaults().objectForKey("authToken") {
            authTokenOfHelper = token as! String
        }

        let storyBoard = UIStoryboard.init(name: "Main", bundle: nil)
        let viewController = storyBoard.instantiateViewControllerWithIdentifier("helperMap")
        let navController = UINavigationController.init(rootViewController: viewController)
        self.window?.rootViewController = nil
        self.window?.rootViewController = navController
        self.window?.makeKeyAndVisible()

        helpRequestReceived = true

    }

}

this initialises storyboard.But if my app was killed by system and it is off and device recieves push, after tapping on push nothing is happened.

Seems that I have to use application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) if app is switched off

But how to access userInfo in didFinishLaunchingWithOptions ?

回答1:

You can check this in didFinishLaunching using UIApplicationLaunchOptionsRemoteNotificationKey as launch options.

UIApplicationLaunchOptionsRemoteNotificationKey: Indicates that a remote notification is available for the app to process. The value of this key is an NSDictionary containing the payload of the remote notification. > - alert: Either a string for the alert message or a dictionary with two keys: body and show-view. > - badge: A number indicating the quantity of data items to download from the provider. This number is to be displayed on the app icon. The absence of a badge property indicates that any number currently badging the icon should be removed. > - sound: The name of a sound file in the app bundle to play as an alert sound. If “default” is specified, the default sound should be played.

You can call application:didReceiveRemoteNotification: in application:didFinishLaunchingWithOptions: manually.

Objective C

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

    if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) {
        [self application:application didReceiveRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
    }

   return YES;
}

Swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        if let remoteNotification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {

            self.application(application, didReceiveRemoteNotification: launchOptions![UIApplicationLaunchOptionsRemoteNotificationKey]! as! [NSObject : AnyObject])

        }


        return true
    }

This is in Objective C but the same thing is in Swift. Put this in didFinishLaunchingWithOptions:

NSDictionary *remoteNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (remoteNotif) {
    [self application:application didReceiveRemoteNotification:remoteNotif];
}

Swift:

if let remoteNotif = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {...}
