iOS Swift中的导航控制器至UITabbarcontroller问题与SWRevealViewController

在我的项目中，我有三个tabBar项home、notification和profile。和侧菜单控制器有主页，预订，配置文件和注销。侧栏菜单控制器是使用SWRevealViewController cocopods实现的

当我将侧栏菜单导航到主页选项卡时，已正确选择栏索引并正确导航。当从预订中导航时，它可以正常导航，但导航主页应用程序再次崩溃。控制台输出表示无法将“UINavigationController”（0x10ef79420）类型的值强制转换为“UITabBarController”（0x10ef79970）

因为bookings控制器是自定义视图控制器，其余的是选项卡栏控制器。当导航到预订屏幕时，视图控制器选项卡栏应隐藏，用户再次点击菜单按钮并导航到主页或任何其他控制器

由于预订控制器没有选项卡栏索引而崩溃。因此，如何在不崩溃的情况下导航到具有选定索引项的自定义控制器和tabbar控制器

这是我的截图：

我的故事板截图：

以下是我尝试过的代码：

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    //        tableView.deselectRow(at: indexPath, animated: true)

    let row = indexPath.row

    if row == 0{


        let tabBarController = revealViewController().frontViewController as! UITabBarController


        let storyboard = UIStoryboard(name: "Home", bundle: nil)

        let obj = storyboard.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController

        let navController = UINavigationController.init(rootViewController: obj)
        tabBarController.selectedIndex = (indexPath as NSIndexPath).row
        tabBarController.tabBar.isHidden = false
        self.revealViewController().pushFrontViewController(tabBarController, animated: true)



    } else if row == 1{

        let tabBarController = revealViewController().frontViewController as! UITabBarController

        let storyboard = UIStoryboard(name: "Bookings", bundle: nil)
        let obj = storyboard.instantiateViewController(withIdentifier: "BookingsViewController") as! BookingsViewController
        let navController = UINavigationController.init(rootViewController: obj)
    //            tabBarController.selectedIndex = 1
    //            tabBarController.tabBar.isHidden = false
        self.revealViewController().pushFrontViewController(navController, animated: true)



    } else if row == 2 {

        let tabBarController = revealViewController().frontViewController as! UITabBarController

        let storyboard = UIStoryboard(name: "Profile", bundle: nil)
        let obj = storyboard.instantiateViewController(withIdentifier: "profileViewController") as! profileViewController
        let navController = UINavigationController.init(rootViewController: obj)
        tabBarController.selectedIndex = (indexPath as NSIndexPath).row
        tabBarController.tabBar.isHidden = false
        self.revealViewController().pushFrontViewController(tabBarController, animated: true)


    } else if row == 3 {
        print(indexPath)
        // Log out user from Firebase
        AuthService.signOut(onSuccess: {
            // Present the Sign In VC
     //                PrefsManager.sharedinstance.logoutprefences()
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            let signInVC = storyboard.instantiateViewController(withIdentifier: "signInViewController")
                        self.present(signInVC, animated: true)

      //                self.navigationController?.pushViewController(signInVC, animated: true)

        }) { (errorMessage) in

            ProgressHUD.showError(errorMessage)

        }



    }


}

这里是SWRevealViewController与UINavigationController和UITabBarController的工作代码（Swift 4）

您的Storyborad将是这样的，您不需要直接将

UITabBarController

分配给

RevalViewController（）。frontViewController

需要这样使用

菜单控件的代码如下

import UIKit

class menuViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {

@IBOutlet weak var tblTableView: UITableView!
@IBOutlet weak var imgProfile: UIImageView!

var ManuNameArray:Array = [String]()
var iconArray:Array = [UIImage]()

override func viewDidLoad() {
    super.viewDidLoad()
    ManuNameArray = ["Home","Booking","Profile","Logout"]
    iconArray = [UIImage(named:"home")!,UIImage(named:"message")!,UIImage(named:"map")!,UIImage(named:"setting")!]

    imgProfile.layer.borderWidth = 2
    imgProfile.layer.borderColor = UIColor.green.cgColor
    imgProfile.layer.cornerRadius = 50

    imgProfile.layer.masksToBounds = false
    imgProfile.clipsToBounds = true 
    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return ManuNameArray.count

}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "MenuCell", for: indexPath) as! MenuCell

    cell.lblMenuname.text! = ManuNameArray[indexPath.row]
    cell.imgIcon.image = iconArray[indexPath.row]

    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    let revealviewcontroller:SWRevealViewController = self.revealViewController()

    let cell:MenuCell = tableView.cellForRow(at: indexPath) as! MenuCell
    print(cell.lblMenuname.text!)

    if cell.lblMenuname.text! == "Home"
    {
        print("Home Tapped")

        let mainstoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

        // Here TabbarController is StoryboardID of UITabBarController
        if let tabBarController = mainstoryboard.instantiateViewController(withIdentifier: "TabbarController") as? UITabBarController{

            tabBarController.selectedIndex = 0
            revealviewcontroller.pushFrontViewController(tabBarController, animated: true)
        }
    }
    if cell.lblMenuname.text! == "Booking"
    {
        print("message Tapped")

        let mainstoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let newViewcontroller = mainstoryboard.instantiateViewController(withIdentifier: "BookingViewController") as! BookingViewController
        let newFrontController = UINavigationController.init(rootViewController: newViewcontroller)

        revealviewcontroller.pushFrontViewController(newFrontController, animated: true)
    }
    if cell.lblMenuname.text! == "Profile"
    {
        let mainstoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

        if let tabBarController = mainstoryboard.instantiateViewController(withIdentifier: "TabbarController") as? UITabBarController{

            tabBarController.selectedIndex = 2
            revealviewcontroller.pushFrontViewController(tabBarController, animated: true)
        }
    }
    if cell.lblMenuname.text! == "Logout"
    {
       print("Logout Tapped")
    }
}
}

其他剩余ViewController的代码与以下所有Home、Notification、Profile和Booking的代码相同

import UIKit

class ProfileViewController: UIViewController {

@IBOutlet weak var btnMenuButton: UIBarButtonItem!

override func viewDidLoad() {
    super.viewDidLoad()

    if revealViewController() != nil {

        btnMenuButton.target = revealViewController()
        btnMenuButton.action = #selector(SWRevealViewController.revealToggle(_:))

        view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
        view.addGestureRecognizer(self.revealViewController().tapGestureRecognizer())
    }

  }
}

您是否只需要

主页

部分中的

选项卡？@VRAwesome是的，我需要主页和配置文件屏幕中的选项卡，而不是预订屏幕中的选项卡。可能的问题是
revealViewController（）。frontViewController as！UITABBARC控制器
。似乎
revealViewController（）。frontViewController
可能是导航控制器，如上一个屏幕截图所示。为了帮助您进行调试，请尝试打印
revalviewcontroller（）的类型。frontViewController
，可能frontViewController不是您期望的控制器？太棒了！！你节省了我的时间。。谢谢你的回答，我还有一个疑问，不是这个问题。中的另一个firebase电子邮件更新swift@PvDev您想只更新电子邮件还是同时更新电子邮件和密码？只更新电子邮件而不是密码这里是我尝试的代码：我在控制台中得到的错误是imageData:：：czsm imageData:：：czsm10@gmail.comimageData:：可选（0）写入文档时出错：可选（错误域=FIRAuthErrorDomain代码=17014“此操作是敏感的，需要最近的身份验证。请在重试此请求之前再次登录。”UserInfo={NSLocalizedDescription=此操作是敏感的，需要最近的身份验证。请在重试此请求之前再次登录。错误\u name=错误\u需要\u最近的\u登录}）
