}

For Receiver By Launching

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

NSDictionary* userInfo =

    [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

    if (userInfo) {

         

     }

}

For Register to Server

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

 NSString *deviceTokenString = [NSString stringWithFormat:@"%@", deviceToken];

    deviceTokenString = [deviceTokenString stringByReplacingOccurrencesOfString:@"<" withString:@""];

    deviceTokenString = [deviceTokenString stringByReplacingOccurrencesOfString:@">" withString:@""];

    deviceTokenString = [deviceTokenString stringByReplacingOccurrencesOfString:@" " withString:@""];

//Resgister to Server

}

//Set Notification

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)

{

    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings 

     settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)      

categories:nil]];

    [[UIApplication sharedApplication] registerForRemoteNotifications];

}

else

{

    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:

     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];

}

if([[UIApplication sharedApplication] applicationState] != UIApplicationStateBackground) {

  // Do stuff  

}
