我是迅速入门的人,我真的很想解决此问题。我正在尝试的是将数据从tableview传递到另一个视图,但是当我运行代码时,它只会显示空白的tableview。这是我在源tableviewcontroller中的代码:
import UIKit
class C1TableViewController: UITableViewController {
var categorisePagePOneName = ["CLOTHING", "SHOES", "ACCESSORIES", "THEME"]
var selectedIndex = Int()
override func viewDidLoad() {
super.viewDidLoad()
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return categorisePagePOneName.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cellIdt = "Conecell"
let cell = tableView.dequeueReusableCell(withIdentifier: cellIdt, for: indexPath) as! C1TableViewCell
cell.textLabel?.text = categorisePagePOneName[indexPath.row]
// Configure the cell...
return cell
}
func laodForNextPage(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath, segue: UIStoryboardSegue, sender: AnyObject?) {
performSegue(withIdentifier: "connect2", sender: self)
self.selectedIndex = indexPath.row
if segue.identifier == "connect2" {
let vc = segue.destination as! C2TableViewController
vc.firstRow = categorisePagePOneName[self.selectedIndex]
}
}
}
然后这是我在另一个tableViewController中的代码:
import UIKit
class C2TableViewController: UITableViewController {
var firstRow: String!
var secondArray: [String] = []
var clothingCat = ["ALL CLOTHING", "THEME", "JACKET", "T-SHIRT", "SHIRT", "SWEATSHIRT", "HOODIES", "PANTS", "JEANS", "SHORTS", "KNITWEAR", "VESTS"]
var shoesCat = ["ALL SHOES", "THEME", "BOOTS", "SANDALS", "SNEAKERS"]
var asscessoriesCat = ["ALL ASSCESSORIES", "THEME", "HAT","BAGS", "JEWELLERY", "EYEWEAR", "WATCHES", "WALLETS", "SOCKS", "UNDERWEAR"]
var themeCat = ["VINTAGE", "KOREA","JAPAN", "SPORTY"]
override func viewDidLoad() {
super.viewDidLoad()
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return secondArray.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "C2", for: indexPath) as! C2TableViewCell
// Configure the cell...
switch firstRow {
case "CLOTHING":
secondArray = clothingCat
case "SHOES":
secondArray = shoesCat
case "ASSCESSORIES":
secondArray = asscessoriesCat
case "THEME":
secondArray = themeCat
default:
break
}
cell.textLabel?.text = secondArray[indexPath.row]
return cell
}
}
我不确定在这种情况下是否正确使用了开关

替换(自定义方法laodForNextPage
仍然没有用)
func laodForNextPage(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath, segue: UIStoryboardSegue, sender: AnyObject?) {
performSegue(withIdentifier: "connect2", sender: self)
self.selectedIndex = indexPath.row
if segue.identifier == "connect2" {
let vc = segue.destination as! C2TableViewController
vc.firstRow = categorisePagePOneName[self.selectedIndex]
}
}
使用
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
performSegue(withIdentifier: "connect2", sender: indexPath)
}
并实施
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "connect2" {
let indexPath = sender as! IndexPath
let vc = segue.destination as! C2TableViewController
vc.firstRow = categorisePagePOneName[indexPath.row]
}
}
您可以删除selectedIndex

您需要在发送者为indexPath时添加此功能
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
}
