From iOS7, we can go back (popViewController) by swiping the view edge.
However, this doesn’t work when customView is set to navigationItem.leftBarButtonItems.

I found a solution here, but it likely to crash when swiping during popViewController animation (I found Pinterest v.3.7 also has this bug).
Additionally, I think this solution is difficult for almost all apps to apply, because they might not have a root class of UINavigationController.

This library is an improvement of the solution above.

Usage

Just set viewController to sharedInstance at viewDidAppear.

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [HCPopBackGestureProxy sharedInstance].viewController = self;
}

and, call viewWillDisappear at viewWillDisappear.

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [[HCPopBackGestureProxy sharedInstance] viewWillDisappear];
}

If you want to disable this gesture partly, implement the protocol method and return NO like below.

- (BOOL)hcPopBackGestureProxyShouldBegin:(UIGestureRecognizer *)recognizer {
  // do something...
  return NO;
}
