Ios Swift自定义返回按钮和目的地

我目前正在我的应用程序中使用SWRevealViewController作为侧边栏菜单。当我单击其中一个选项时，目标视图控制器没有“后退”按钮，因为它不是来自正确的视图控制器（即返回的页面）

因此，我想在目标视图控制器上手动创建一个返回按钮，该按钮将返回主视图控制器

我在这里查看了代码：

但我正努力在Swift中实现这一点（一个接一个的错误！）。有什么帮助吗？谢谢

我尝试了下面的建议，但是“后退”按钮没有出现。这可能与我将导航栏隐藏在其他视图中，并在目标视图上执行以下操作有关：

override func viewDidLoad() {
    super.viewDidLoad()
    navigationController.setNavigationBarHidden(false, animated:true)
    var myBackButton:UIButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    myBackButton.addTarget(self, action: "popToRoot:", forControlEvents: UIControlEvents.TouchUpInside)

    var myCustomBackButtonItem:UIBarButtonItem = UIBarButtonItem(customView: myBackButton)
    self.navigationItem.leftBarButtonItem = myCustomBackButtonItem
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

func popToRoot(sender:UIBarButtonItem){
    self.navigationController.popToRootViewControllerAnimated(true)
}

不知道为什么后退按钮不会出现

这是我的侧栏视图控制器中的prepareForSegue。如果有办法检查segue标识符“test”，那么我可以从这里设置back按钮吗

- (void) prepareForSegue: (UIStoryboardSegue *) segue sender: (id) sender
{
// Set the title of navigation bar by using the menu items
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
UINavigationController *destViewController = (UINavigationController*)segue.destinationViewController;
destViewController.title = [[_menuItems objectAtIndex:indexPath.row] capitalizedString];


if ( [segue isKindOfClass: [SWRevealViewControllerSegue class]] ) {
    SWRevealViewControllerSegue *swSegue = (SWRevealViewControllerSegue*) segue;

    swSegue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc) {

        UINavigationController* navController = (UINavigationController*)self.revealViewController.frontViewController;
        [navController setViewControllers: @[dvc] animated: NO ];
        [self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];
    };

}

}

你可以这样用swift写

编写此命令可添加

navigationController上的按钮

    navigationController.setNavigationBarHidden(false, animated:true)
    var myBackButton:UIButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    myBackButton.addTarget(self, action: "popToRoot:", forControlEvents: UIControlEvents.TouchUpInside)
    myBackButton.setTitle("YOUR TITLE", forState: UIControlState.Normal)
    myBackButton.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)
    myBackButton.sizeToFit()
    var myCustomBackButtonItem:UIBarButtonItem = UIBarButtonItem(customView: myBackButton)
     self.navigationItem.leftBarButtonItem  = myCustomBackButtonItem

这将弹出到
rootViewController

    func popToRoot(sender:UIBarButtonItem){
       self.navigationController.popToRootViewControllerAnimated(true)
    }

以下是Swift 2/2.1的更新版本：

self.navigationController? .setNavigationBarHidden(false, animated:true)
let backButton = UIButton(type: UIButtonType.Custom)
backButton.addTarget(self, action: "methodCall:", forControlEvents: UIControlEvents.TouchUpInside)
backButton.setTitle("TITLE", forState: UIControlState.Normal)
backButton.sizeToFit()
let backButtonItem = UIBarButtonItem(customView: backButton)
self.navigationItem.leftBarButtonItem = backButtonItem

在Swift 2.1中

我正在以这种方式自定义导航栏项目


我可以更改导航栏背景图像、标题文本、文本颜色
我可以显示/隐藏后退按钮
我可以更改标题/图标或自定义操作方法

在AppDelegate中我有

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
    {
        //Cutomize navigation bar
        let navBgImage:UIImage = UIImage(named: "dummy_navigation_bg_image")!
        UINavigationBar.appearance().setBackgroundImage(navBgImage, forBarMetrics: .Default)
        UINavigationBar.appearance().tintColor = UIColor.whiteColor()
        UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()];


        return true
    }

在ViewController中我更新viewwilldisease方法中的导航项

override func viewWillAppear(animated: Bool)
    {
        super.viewWillAppear(animated)
        setupNavigationBar()
    }

    // MARK: - NavigationBar methods
    func setupNavigationBar ()
    {

        //current tab screen title
        tabBarController?.title = "Manage"

        //Hide back button or left bar button
        tabBarController?.navigationItem.leftBarButtonItem = UIBarButtonItem(title: " ", style: .Plain, target: nil, action: nil)

        //custom right bar button
        var image = UIImage(named: "dummy_settings_icon")
        image = image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
        tabBarController?.navigationItem.rightBarButtonItem = UIBarButtonItem(image: image, style: UIBarButtonItemStyle.Plain, target: self, action:  "settingButtonAction")
    }

    func settingButtonAction()
    {
        print("Setting Button tapped")
        performSegueWithIdentifier("loadAccountSettingsSegue", sender: nil)

    }

Swift 3.0解决方案：

    self.navigationController?.setNavigationBarHidden(false, animated:false)

        //Create back button of type custom

        let myBackButton:UIButton = UIButton.init(type: .custom)
        myBackButton.addTarget(self, action: #selector(ViewController.popToRoot(sender:)), for: .touchUpInside)
        myBackButton.setTitle("Back".localized(), for: .normal)
        myBackButton.setTitleColor(.blue, for: .normal)
        myBackButton.sizeToFit()

       //Add back button to navigationBar as left Button

        let myCustomBackButtonItem:UIBarButtonItem = UIBarButtonItem(customView: myBackButton)
        self.navigationItem.leftBarButtonItem  = myCustomBackButtonItem



 func popToRoot(sender:UIBarButtonItem){
        _ = self.navigationController?.popToRootViewController(animated: true)
    }

Swfit 5/XCode 11.4

override func viewDidLoad() {
    super.viewDidLoad()

    navigationController!.setNavigationBarHidden(false, animated: true)
    let myBackButton:UIButton = UIButton(type: UIButton.ButtonType.custom) as UIButton
    myBackButton.addTarget(self, action: #selector(popToRoot), for: UIControl.Event.touchUpInside)
    myBackButton.setTitle("YOUR TITLE", for: UIControl.State.normal)
    myBackButton.setTitleColor(UIColor.white, for: UIControl.State.normal)
    myBackButton.sizeToFit()
    let myCustomBackButtonItem:UIBarButtonItem = UIBarButtonItem(customView: myBackButton)
     self.navigationItem.leftBarButtonItem  = myCustomBackButtonItem
}

另外，poptroot应该标记为@objc

 @objc func popToRoot() {
        //enter action here
    }

感谢回复，我在上面的帖子中添加了更多内容，因为你已经隐藏了导航栏，它不会显示。为什么你要隐藏
navigationBar
，因为我的大多数应用程序都不需要它，但我允许它显示在这个视图中。当我应用上述代码时，后退按钮不会出现。导航栏标题显示“精细”，将按钮放置在任何位置，并相应设置其边框。请参见我编辑的答案这意味着我将丢失股票左箭头右箭头？有没有办法保留它？你修好了吗？我也有同样的问题
