ios - 如何将数据从 UI Table View 传递到 Table View Cell 内的 UI Collection View？

Question

我使用 xib 在我的 TableView 单元格上有 ui Collection View 。我想将从 API 获取的数据传递到 TableView 单元格内的 ui Collection View

这是我的代码

型号

class MessageTextType {

var messageType: String = ""
var messageFromMe: String = ""
var date: String = ""
var type: String = ""
var text: String = ""
var image: String = ""
var imagePreview: String = ""
var time: String = ""
var speech: String = ""
var resolvequery: String = ""
var columnCarousel: String = ""


}

    class ViewController : UIViewController {   

    }

    extension ViewController:UITableViewDataSource,UITableViewDelegate{
        // this is for your tableView
     In your tableView Cell :-

            if yourModelData != nil{
             // reload collectionView
            }

                        return cell
        }
    }
