Question

我需要从tableview和我的代码中选择单元格如下：

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
    let vc = OfferDetailViewController(nibName: "OfferDetailViewController", bundle: nil)
    let indexPath = (self.tableView.indexPathForSelectedRow)!
    let offerViewModel1 = self.offerViewModel.sourceAt(index: indexPath.row)
    vc.offerViewModel2 = offerViewModel1
    navigationController?.pushViewController(vc, animated: true)
}

我正在使用mvvm方法。我有两个屏幕。

在tableview中列出数据
从tableview中选择单元格时，必须转到其他屏幕。它包含详细信息。

我已经完成了列出数据。但点击我需要通过他传球。怎么做？我无法理解它应该传递给viewmodel或viewcontroller。

foodviewmodel： -

class foodViewModel: NSObject {

    var datasourceModel:foodDataSource

    init(withdatasource  offerDatasourceModel: foodDataSource) {
        datasourceModel = offerDatasourceModel
    }


    func datafordisplay(atindex indexPath: IndexPath) -> foodModel{
        return  datasourceModel.dataListArray![indexPath.row]

    }


   func numberOfRowsInSection(section:Int) -> Int {

      return (datasourceModel.dataListArray?.count)!
  }


    //indexpath.....
   // func sourceAt(atindex indexPath: IndexPath) -> foodModel {
      //  return self.datasourceModel.dataListArray![indexPath.row]
   // }

    func sourceAt(index :Int) -> foodModel  {
        return self.datasourceModel.dataListArray![index]
    }
}

foodDataSource .swift： -

  var dataListArray:Array<foodModel>? = []


    init(array :Array<[String:Any]>?) {
        super.init()
        var newArray:Array<[String:Any]> = []
        if array == nil{

            newArray = self.getJsonDataStored4()
        }
        else{
            newArray = array!

        }

        var datalist:Array<foodModel> = []
        for dict in newArray{

            let model = foodModel(dictionary: dict)

            datalist.append(model!)
        }
        self.dataListArray = datalist
    }



}

typealias dummyDataSource4 = foodDataSource
extension dummyDataSource4{

    func getJsonDataStored4() ->Array<Dictionary<String,String>>{

        let jsonArray = [["id":"1","name":"Lunch Buffet","price":"Q28","location":"Doha, Qatar","imageurl":"","offertype":"Today's Offer","restaurtantname":"MOMS KITCHEN"],["id":"2","name":"Economy Meal","price":"Q65","location":"Doha, Qatar","imageurl":"","offertype":"Tomorrow's Offer","restaurtantname":"Mr.Shawarma"],["id":"3","name":"Sit-Down Buffet","price":"Q65","location":"Doha, Qatar","imageurl":"","offertype":"Weekend's Offer","restaurtantname":"Maharaja Darbar"],["id":"4","name":"Lunch Buffet","price":"Q28","location":"Doha, Qatar","imageurl":"","offertype":"Today's Offer","restaurtantname":"Shircz Garden"]] as Array<Dictionary<String,String>>

        return jsonArray
    }


    Then i created fooddetailmodel,fooddetaildatasource,fooddetailviewmodel classes.

但我不知道该传递什么

我已经给出了代码： -

var offerViewModel2 :QM_OfferModel!

// @IBOutlet private weak var tableView：UITableView！

 override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

 }

单击mvvm中的单元格时传递数据
