Objective c 以TabBarController作为初始视图的PKRevealController

我为我的应用程序设置了一个PKRevealController菜单，效果非常好。但是，我想把菜单放在位于选项卡栏控制器内部的视图上。目前，它仅适用于未嵌入选项卡栏控制器内部的视图。有人知道我怎样才能做到吗

请参阅下面的现有代码

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.revealController = (PKRevealController *)self.window.rootViewController;
    UIViewController *leftViewController = [[LeftMenuViewController alloc] init];
    PKRevealController *frontViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"MainNavViewController"];
    [self.revealController setFrontViewController:frontViewController];
    [self.revealController setLeftViewController:leftViewController];
    return YES;
}
