如何在将单元格重新加载到另一个视图控制器后传递数据

Question

我有一个视图控制器，它在第一个视图控制器中对单元格进行重新排序，但重新排序没有反映在第二个视图控制器上。我尝试使用结构来传递数据，但这是不可能的。使用commonInit I将详细信息传递给第二视图控制器

import UIKit
import CoreData
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return name.count
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return  95
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cellId", for: indexPath) as! PizzaListTableViewCell
/*  let data = pizza[indexPath.row]

cell.textLabel?.text = data.name
cell.textLabel?.text = data.miscellaneousText
cell.textLabel?.text = data.amount */
cell.commonInit(_imageName: "pizza_(indexPath.item)", title:name[indexPath.item], text: miscellaneousText[indexPath.item], amount: amount[indexPath.item])
return cell
}
func  tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let vc = DetailsVC()
vc.commonInit("pizza_(indexPath.item)", title:name[indexPath.item],text: miscellaneousText[indexPath.item], amount: amount[indexPath.item],pizzaTextField: pizzaToppings[indexPath.item])

self.navigationController?.pushViewController(vc, animated: true)
self.tableView.deselectRow(at: indexPath, animated: true)
}
func tableView(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {

let item = name[sourceIndexPath.row]
name.remove(at: sourceIndexPath.row)
name.insert(item, at: destinationIndexPath.row)

}

下一个视图控制器名称是DetailsVC((。重新排序不会反映在此视图控制器中

import UIKit
import CoreData
class DetailsVC: UIViewController, UIPickerViewDataSource ,UIPickerViewDelegate{
let name = ["Bacon Cheese Fry","Pizza Margherita"]
let miscellaneousText = ["Accepted","Accepted"]
let amountArr = ["39.99","39.99"]

@IBOutlet weak var detailImage: UIImageView!
var imageName: String!
var titleName: String!

@IBOutlet weak var text: UILabel!
var textName: String!

var textDescript: String!

@IBOutlet weak var amount: UILabel!
var amountName: String!
func commonInit(_ imageName: String, title: String, text: String, amount: String,pizzaTextField:String)
{
self.imageName = imageName
self.title = title
self.textName = text
self.amountName = amount
self.pizzaText = pizzaTextField


}

Answer 1

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let storyBoard = UIStoryboard(name: "StoryboardName", bundle: nil)
let vc =  storyBoard.instantiateViewController(withIdentifier: "yourVCIdentifier") as? DetailsVC
vc?.commonInit("pizza_(indexPath.item)", title:name[indexPath.item],text: miscellaneousText[indexPath.item], amount: amount[indexPath.item],pizzaTextField: pizzaToppings[indexPath.item])
self.navigationController?.pushViewController(vc, animated: true)
self.tableView.deselectRow(at: indexPath, animated: true)
}

编辑：

使用XIB

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let vc =  DetailVC(nibName: "YourNibName", bundle: nil)
vc.commonInit("pizza_(indexPath.item)", title:name[indexPath.item],text: miscellaneousText[indexPath.item], amount: amount[indexPath.item],pizzaTextField: pizzaToppings[indexPath.item])
self.navigationController?.pushViewController(vc, animated: true)
self.tableView.deselectRow(at: indexPath, animated: true)
}
