Slide back in UINavigationController like in Facebook for iOS

Question

I saw the Facebook app update for iOS (6.1.1) and it has a rely nice slide back function. For now I have a UISlideGestureRecognizer that when is called a do a [self.navigationController popViewController:YES];. But how can I make it with a UIPanGestureRecognizer like in the Facebook app? Should I build my own UINavigationController?

I do not know more than this (yet):

backView1 = [[self.navCon.viewControllers objectAtIndex:self.navCon.viewControllers.count - 2] view];
backView2 = [[self.navCon.viewControllers objectAtIndex:self.navCon.viewControllers.count - 1] view];

Please help in advance!

I've created a subclass of UINavigationController to do that. Here you go: https://github.com/MarcoSero/MSSlideNavigationController

if you're talking about slide out menu you can partially 'swipe', see this for several examples.

No, I'm more talking about: when you are in the newsfeed and then touch a story (The Facebook app shows that story with some code lik: [self, navigationController pushViewController:con];) then when you want to go back you can now slide your finger from left to right to go back to the news feed.

To add effect of Slide back in UINavigationController add the following code line and add gesture recognizer delegate

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
        self.navigationController.interactivePopGestureRecognizer.delegate = self;
    }
}


- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    return YES;
}
