Question

I have used Push notification in my application, when the notification arrives i will get some values in the payload and i need to update the values in my application. I have amount label in all the views, so i need to update the amount after receiving the notification. But the problem is, the value doesn’t update instantly, when i navigate to any view after that it will update. I want to update the value instantly, so how can i do that?

-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{

            NSString *getAmt =[[userInfo valueForKey:@"aps"] valueForKey:@"Amount"];
            float totalAmt = [getAmt floatValue] + [amt floatValue];
            NSString *finalAmount = [NSString stringWithFormat:@"%.02f",totalAmt];
            [[NSUserDefaults standardUserDefaults] setObject:finalAmount forKey:@"amount"];
            [self.viewController.view setNeedsDisplay];
}

I am using the Nsuserdefault value for displaying the amount in the amount label. Now the values are changed, when i am navigates to any view after that it will update. But i want to update the value instantly in my application, after getting the notification. So please help me out.

Thanks!

use NSNotication and add a notification against a method of class where method is implemented, when you receive push notification, post that notification and in method update values
