Question

我正在使用SWRevealViewController，我想将视图控制器从菜单视图控制器推送到实际的导航视图控制器。问题是，当我使用self.revealViewController().frontViewController.navigationController!时，这个导航控制器始终是零并且应该是，因为我总是使用导航控制器pushFrontViewController。

如何推动实际的导航控制器？我正在使用故事板。

Answer 1

这是您的解决方案

使用Swrevealviewcontroller从菜单到普通ViewController＆＃34; setFrontViewPosition ＆＃34;

在 Swift

中

        let obj = self.storyboard?.instantiateViewControllerWithIdentifier("ViewController") as! ViewController
        let navController = UINavigationController(rootViewController: obj)
        navController.setViewControllers([obj], animated:true)
        self.revealViewController().setFrontViewController(navController, animated: true)
        self.revealViewController().setFrontViewPosition(FrontViewPosition.Left, animated: true)

在Objectctive-c

中

 -(void)main{
     LoginViewController *tar = [self.storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"];
     UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:tar];
     [navController setViewControllers: @[tar] animated: YES];

    [self.revealViewController setFrontViewController:navController];
    [self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];
}

Answer 2

我猜您正在尝试调用UINavigationcontroller的UINavigationcontroller

revealViewController（）。frontViewController已经给我UINavigationcontroller

我在侧边菜单控制器中有此功能，

override func shouldPerformSegue(withIdentifier identifier: String, sender: Any?) -> Bool {

    var controller: UIViewController?
    var navController: UINavigationController?

    if identifier.hasSuffix("Orders")  {
        controller = self.storyboard?.instantiateViewController(withIdentifier: "ShowOrdersViewController") as! ShowOrdersViewController
        (controller as! ShowOrdersViewController).orderType = identifier
        navController = revealViewController().frontViewController as! UINavigationController
    }

    self.revealViewController().revealToggle(animated: true)
    navController?.pushViewController(controller!, animated: true)

    return false
}

SWRevealViewController推送到实际的导航控制器
