There are few ways/ But I prefer using https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSNotificationCenter_Class/index.html

Somrewere in constants

NSString *const NOTIFICATION_ID = @"com.yourapp.notificationID";

ViewController.m

- (void)viewDidLoad
{
    NSNotificationCenter * notificationCenter = [NSNotificationCenter defaultCenter];
    [notificationCenter addObserver:self
                               selector:@selector(notificationRecieved:)
                                   name:NOTIFICATION_ID
                                 object:nil];
}

- (void)notificationRecieved:(NSNotification*)notification
{
    NSLog(@"Push received: %@", notification.userInfo);
}

- (void)dealloc
{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:NOTIFICATION_ID object:nil];
}

AppDelegate.m

-(void)application:(UIApplication*)application didReceiveRemoteNotification: (NSDictionary*)userInfo 
{
    [[NSNotificationCenter defaultCenter] postNotificationName:NOTIFICATION_ID object:nil userInfo:userInfo];
}

Use Notifications. The app delegate will post the notification with the notification dictionary, the view controller will be listening for it.
