I Add this type of functionality for whole project, i add the QRView in window so user swip up the view from any view of project…

See the Example of my code..

Just set the UISwipeGestureRecognizer to your second view which you want to present like bellow…

 CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.5];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.view layer] addAnimation:animation forKey:kAnimationKey];
    UISwipeGestureRecognizer *swipeGesture = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(addCustomBottomBar)] autorelease];
    swipeGesture.numberOfTouchesRequired = 1;
    swipeGesture.direction = (UISwipeGestureRecognizerDirectionDown);
    [yourViewController.view addGestureRecognizer:swipeGesture];/// use your view name here, its depends on your requirement
    UISwipeGestureRecognizer *swipeGestureTop = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(addCustomBottomBar)] autorelease];
    swipeGestureTop.numberOfTouchesRequired = 1;
    swipeGestureTop.direction = (UISwipeGestureRecognizerDirectionUp);

    [yourViewController.view addGestureRecognizer:swipeGestureTop];

and this bellow method called when you swipe up view…

Also just add one BOOL variable with name isViewPop and set it to NO in your viewDidLoad: method ..

-(void)addCustomBottomBar{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.window cache:YES];

    if (isqrcodepop) {
        isViewPop=NO;

        yourViewController.view.frame=CGRectMake(0, 430, 320, 70);
    }
    else{
        isViewPop=YES;

        yourViewController.view.frame=CGRectMake(0, 210, 320, 270);
        [self.view bringSubviewToFront:yourViewController.view];
    }
    [UIView commitAnimations];
}

i hope this answer helpful for you…
