有没有办法可以识别与 viewController 关联的 .storyboard？

Question

在storyboard 中，可以找到关联viewController 的id。但据我所知，反过来是不可能的：也就是说，在viewController 中，我能看到storyboard 连接到什么吗？

问题是，我目前正在使用 viewController，但不知道它与 storyboard 相关联。

这是来自 Shreeram-Bhat 建议的代码：

import UIKit

protocol PickNumberVieDelegate: class {
    func dismissPickNumberView(tempDef:String, tempAlter:String)
}

class PickNumberViewController: UIViewController,UITableViewDataSource, UITableViewDelegate{

    weak var delegate: PickNumberVieDelegate?
    var whatTypOfNumber = 0
    @IBOutlet weak var tableview: UITableView!
    @IBOutlet weak var indicator: UIActivityIndicatorView!

    var arr = [PresentationNumberOption]()

    var tempAlernatNr = ""
    var tempDefaultNr = ""

    override func viewDidLoad() {
        super.viewDidLoad()

        //HERE
        var storyboard: UIStoryboard? { get }
        print("????here", storyboard);

        self.setUserInterfaceStyleLight()
        if (whatTypOfNumber == 0) {

            self.title = NSLocalizedString("TimeControlled AfterWork Time" , comment: "")

        }else if (whatTypOfNumber == 1){
            self.title = NSLocalizedString("TimeControlled Showing Number" , comment: "")
        }else{

            self.title = NSLocalizedString("Display Number", comment: "")
        }

    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        var mobilNumber = ""
        if  let mobileNumberForThisDevice = CurrentPerson.shared().thisMobilePhone(){

您可以从“故事板”属性中获取它。下面是属性的声明。

var storyboard: UIStoryboard? { get }

如果您从代码中实例化了 ViewController，它将为零。你懂的，

if let storyboard = self.storyboard {
            if let name = storyboard.value(forKey: "name") as? String {
                print(name)
            }
}
