Present系统原生分享框架 不兼容 , 选择短信Message的时候，导航栏cancel按钮被遮盖

[shineFoyMylove]

UIActivityViewController` *actContr = [[UIActivityViewController alloc] initWithActivityItems:@[screenImage]  applicationActivities:nil];
[self presentViewController:actContr animated:YES completion:nil];

系统原生分享，选择短信Message，Present MFMessageComposeViewController 的时候，导航栏被遮盖，导致 cancel 按钮无法点击 dismiss。
找了很久，发现当屏蔽 如下的 method 交换，恢复正常，求这个问题该如何解决？

@implementation UINavigationController (FDFullscreenPopGesture)
+ (void)load{
        SEL originalSelector = @selector(pushViewController:animated:);
        SEL swizzledSelector = @selector(fd_pushViewController:animated:);
        ........
}

MFMessageComposeViewController *messageComposeVC = [[MFMessageComposeViewController alloc] init];
UIViewController *rootViewController = messageComposeVC.viewControllers.firstObject;
rootViewController.fd_prefersNavigationBarHidden = YES;
