Examine iOS Push Notification Payload - ios

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?

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];
}

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.
