如何在iOS Swift中将数据数组回调到另一个viewController [英] how to callback the array of data to another viewController in iOS Swift

问题描述

在createCardVC中，我使用了carbonKit库来显示选项卡栏。最初，使用静态数据加载数据数组，但现在我尝试使用来自webView javascript postMessage的数据数组。

In createCardVC, I have used the carbonKit library to show tab bar. Initially, the array of data loaded using static data but now I am trying to use an array of data from webView javascript postMessage.

1. 加载createCardVC时，第一个选项卡的carbonKit将加载webViewVC。


2. 在webView，从postMessage它将列出数字菜单项以显示选项卡栏菜单。


3. 此处的选项卡值是动态的，并且将从webView postMessage返回。

这是清晰的图片：

这是代码createCardVC：

Here is the code createCardVC:

  override public func viewDidLoad() {
    super.viewDidLoad()

    carbonTabSwipeNavigation = CarbonTabSwipeNavigation(items: ["Basic Details"], delegate: self)
    carbonTabSwipeNavigation.insert(intoRootViewController: self, andTargetView: infoView)
    carbonTabSwipeNavigation.toolbar.barTintColor = UIColor.white
    carbonTabSwipeNavigation.setSelectedColor(UIColor.black)
    carbonTabSwipeNavigation.setIndicatorColor(UIColor(hexString: "#363794")) 

}//viewdidload

func onUserAction(data: String)
{
    print("Data received: \(data)")
}


func sampleDelegateMethod(arg: Bool,completion: (Bool) -> ()){

    completion(arg)

    let singleTon = SingletonClass()
            print(singleTon.sharedInstance.dataText)
}


@IBAction func backBtn(_ sender: Any) {

   _ = navigationController?.popViewController(animated: true)
    navigationController?.setNavigationBarHidden(false, animated: true)
    tabBarController?.tabBar.isHidden = false


}



public init() {

         super.init(nibName: "CreateCardViewController", bundle: Bundle(for: CreateCardViewController.self))
     }

     required init?(coder aDecoder: NSCoder) {

         fatalError("init(coder:) has not been implemented")

     }

public func carbonTabSwipeNavigation(_ carbonTabSwipeNavigation: CarbonTabSwipeNavigation, viewControllerAt index: UInt) -> UIViewController {


    return firstView()

   }
func firstView() -> UIViewController {



    let cont = WebViewController()
    self.tabContView?.addChild(cont)
    self.tabContView?.view.addSubview(cont.view)

    cont.didMove(toParent: tabContView)
    let authToken = UserDefaults.standard.string(forKey: "authToken")

    cont.formKey = formKey
    print("cont vl", formKey ?? "")
    cont.processInstanceId = processInstanceId
    cont.authTokenValue = authToken
    cont.fullFormKey = fullFormKey
    cont.taskIdValue = TaskIdValue


    return cont

}

以下是webView的代码：

Here is the code for webView:

 public func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {

    if message.name == "jsHandler" {
       //  print(message.body)

    } else if message.name == "tabForm" {


        print("dynamic tabs value::::",message.body)

        let tabs = message.body
        let jsonString = JSONStringify(value: tabs as AnyObject)

            if let jsonData = jsonString.data(using: .utf8) {
              do {
                let decoder = JSONDecoder()
                let mainObject = try decoder.decode(DynamicTabsModel.self, from: jsonData)

                print("tab model:::", mainObject)

                createCardVC?.onUserAction(data: "The quick brown fox jumps over the lazy dog")
                delegate?.onPizzaReady(type: "Pizza di Mama")
                createCardVC?.sampleDelegateMethod(arg: true, completion: { (success) -> Void in

                    print("Second line of code executed")
                    if success { // this will be equal to whatever value is set in this method call

                        createCardVC?.onUserAction(data: "The quick brown fox jumps over the lazy dog")
                        delegate?.onPizzaReady(type: "Pizza di Mama")

                        let singleTon = SingletonClass()
                        singleTon.sharedInstance.dataText = "store data"

                        print("delegate method ::: true")


                    } else {
                         print("delegate method ::: false")
                    }
                })

                print("called delegate")

              } catch {

                print(error.localizedDescription)

              }
            }



    }
   }

我的问题是：

1. 如何将标签值从webView返回到CreateCardVC？
   
2. 如何在carbonKit中显示动态选项卡？


3. 如何使用相同的webViewController和url从webViewController返回动态更改下一个选项卡的ViewController。

任何帮助都值得赞赏...

Any help much appreciated pls...

推荐答案

您可以尝试使用 GLViewPagerController ，它更具动态性，API与 UITableView相似。

You can try using "GLViewPagerController" it is more dynamic and API is similar to "UITableView"
