iOS 完美解决iOS7 interactivePopGestureRecognizer 手势冲突

重写导航控制器，在其代理实现：

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    BOOL isRootVC = viewController == navigationController.viewControllers.firstObject;
    navigationController.interactivePopGestureRecognizer.enabled = !isRootVC;
}
