FDFullscreenPopGesture使用setViewControllers跳转一个隐藏导航栏新页面失效问题

解决办法：

1.对setViewControllers:animated:进行方法交换

SEL originalSelector1 = @selector(setViewControllers:animated:);

            SEL swizzledSelector1 = @selector(fd_setViewControllers:animated:);

            Method originalMethod1 = class_getInstanceMethod(class, originalSelector1);

            Method swizzledMethod1 = class_getInstanceMethod(class, swizzledSelector1);

            BOOL success = class_addMethod(class, originalSelector1, method_getImplementation(swizzledMethod1), method_getTypeEncoding(swizzledMethod1));

            if (success) {

                class_replaceMethod(class, swizzledSelector1, method_getImplementation(originalMethod1), method_getTypeEncoding(originalMethod1));

            } else {

                method_exchangeImplementations(originalMethod1, swizzledMethod1);

            }

2.实现交换后的方法

- (void)fd_setViewControllers:(NSArray<UIViewController *> *)viewControllers animated:(BOOL)animated {

    [self fd_setupViewControllerBasedNavigationBarAppearanceIfNeeded:viewControllers.lastObject];

    [self fd_setViewControllers:viewControllers animated:animated];

}
