What's the best way to develop a sideswipe menu like the one in Facebook's new iOS app?

Question

There is a great library for this by Tom Adriaenssen: Inferis/ViewDeck

It's very easy to use and has a fairly large following.

EDIT:

For something a little more lightweight, check out: mutualmobile/MMDrawerController

It doesn't have all of the features of ViewDeck but is simpler to modify and extend.

I created a library for this. It is called MFSideMenu.

Among other things it includes support for iphone+ipad, portrait+landscape, menu on the left or right side, UITabBarController, and pan gestures.

I recently came across this, didn't actually look at the code or test the control, but looks like it may be a very decent starting point.

Check out MMDrawerController:

We couldn't find a library that we liked, so we just rolled our own.

The key idea that you have to set self.navigationController.view's frame or center. There is two event that you have to handle. (1) barButtonItem press. (2) pan gesture because of swiping.

You can send view controller to the background like this:

[self.view sendSubviewToBack:menuViewController.view];

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(buttonPressed:)];
    UIPanGestureRecognizer *panGestureRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
    [self.navigationController.view addGestureRecognizer:panGestureRecognizer];
    self.navigationItem.leftBarButtonItem = barButtonItem;
}

- (void)buttonPressed:(id)sender {

    CGRect destination = self.navigationController.view.frame;

    if (destination.origin.x > 0) {
        destination.origin.x = 0;
    } else {
        destination.origin.x = 320;
    }

    [UIView animateWithDuration:0.25 animations:^{
        self.navigationController.view.frame = destination;
    }];
}

- (void)handlePan:(UIPanGestureRecognizer *)recognizer
{
    static CGPoint originalCenter;

    if (recognizer.state == UIGestureRecognizerStateBegan)
    {
        originalCenter = recognizer.view.center;

    } else if (recognizer.state == UIGestureRecognizerStateChanged)
    {
        CGPoint translation = [recognizer translationInView:self.view];

        recognizer.view.center = CGPointMake(originalCenter.x + translation.x, originalCenter.y);
    }
    else if (recognizer.state == UIGestureRecognizerStateEnded || recognizer.state == UIGestureRecognizerStateCancelled || recognizer.state == UIGestureRecognizerStateFailed)
    {
        if (recognizer.view.frame.origin.x < 160) {
            [UIView animateWithDuration:0.25 animations:^{
                recognizer.view.center = CGPointMake(384, 487.5);
            }];
        } else {
            [UIView animateWithDuration:0.25 animations:^{
                recognizer.view.center = CGPointMake(384 + 320, 487.5);
            }];
        }
    }
}
