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

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
NSLog(@"%s",__FUNCTION__);

if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
    self.interactivePopGestureRecognizer.enabled = NO;

[super pushViewController:viewController animated:animated];
}

#pragma mark UINavigationControllerDelegate
- (void)navigationController:(UINavigationController *)navigationController
   didShowViewController:(UIViewController *)viewController
                animated:(BOOL)animate
{
NSLog(@"%s",__FUNCTION__);

// Enable the gesture again once the new controller is shown

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