result of telprompt:

Question

Is there any way to determine when the user comes back to the app from telprompt? If they hit cancel I don't want to do anything but if they hit call when they come back to the app I want to take an action. Thanks.

NSNotificationCenter * center =
    [NSNotificationCenter defaultCenter];

    [center addObserverForName:UIApplicationDidBecomeActiveNotification
                        object:nil
                         queue:[NSOperationQueue mainQueue]
                    usingBlock:^(NSNotification *note)
    {
        // use instance flag to know
        if (self.isBackfromCalling)
        {
            // do some stuff
        }
    }];
