Examine iOS Push Notification Payload

Question

I'm trying to figure out how I can examine the payload of a push notification in order to determine which view opens when a user opens the app from the notification. For example, if a notification says "x: test" view x would open when the notification is tapped and if the notification says "y: test" view y would open.

EDIT: I guess I should clarify the part I'm not sure about.

I have this in didFinishLaunchingWithOptions:

UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

    if (notification)
    {
        // check payload then load appropriate view controller
    }

How would I check the payload for certain text in order to determine the appropriate view controller to load?

Have you done any search? In application didFinishLaunchingWithOptions method in AppDelegate.m you read the remote notification and depending on what is "says" with an if-statement you open the correct view. — Kostis, Nov 04 '14 at 20:23

Receiving a push notification is handled in two places in the app delegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions when your app is launched from a push notification. In this case, your push notification data is contained within [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo when your app is running when receiving the notification. In this case, userInfo is your push notification data.

See my update. I've clarified what I'm not sure about. – raginggoat Nov 04 '14 at 20:45 — raginggoat, Nov 04 '14 at 20:45

Here is my code from a past project. The notification shows up in device like this "Kostas: wants to add you as friend".

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

NSDictionary *remoteNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

if (remoteNotif) {

    NSString *name = [[NSString alloc] init];
    NSString *message = [[NSString alloc] init];
    // 'wants to add you as friend.'
    NSString* alertValue = [[remoteNotif valueForKey:@"aps"] valueForKey:@"alert"];

    NSMutableArray* parts = [NSMutableArray arrayWithArray:[alertValue componentsSeparatedByString:@": "]];
    name = [parts objectAtIndex:0];
    [parts removeObjectAtIndex:0];
    message = [parts componentsJoinedByString:@": "];

    if ([message isEqualToString:@": wants to add you as friend."]) {
        UITabBarController *tabController = (UITabBarController *)self.window.rootViewController;
        // tabController.delegate = self;
        tabController.selectedIndex = 1;
    }
    else{
        UITabBarController *tabController = (UITabBarController *)self.window.rootViewController;
        // tabController.delegate = self;
        tabController.selectedIndex = 2;

        [self addMessageFromRemoteNotification:remoteNotif updateUI:NO];
    }
