Solution

The interactive pop gesture recognizer is exposed through `UINavigationController`'s `interactivePopGestureRecognizer` property. You can add your own controller as a target of the gesture recognizer and respond appropriately:

@implementation MyViewController

...

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self.navigationController.interactivePopGestureRecognizer addTarget:self 
                                                                  action:@selector(handlePopGesture:)];
}


- (void)handlePopGesture:(UIGestureRecognizer *)gesture
{
    if (gesture.state == UIGestureRecognizerStateBegan)
    {
        // respond to beginning of pop gesture
    }
    // handle other gesture states, if desired
}

...

@end

Problem

In the new iOS 7 `UINavigationController`, there is a swipe gesture to switch between views. Is there a way to detect or intercept the gesture?
