displaying array items in tableview with swift
提问by Timur Aykut YILDIRIM
I cannot display elements of an array in a tableview by using swift programming language. I did some research but could not solve the problem. Below, you can see my code and download project as a .zip file from here: http://1drv.ms/1Ca2hyp
我无法使用 swift 编程语言在 tableview 中显示数组的元素。我做了一些研究，但无法解决问题。在下面，您可以从此处查看我的代码并将项目下载为 .zip 文件：http: //1drv.ms/1Ca2hyp
I can also give some videos. They're 11 min and 10 sec. long in total
我也可以提供一些视频。他们是 11 分 10 秒。总长
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet var myTableView: UITableView!
var cars = [String]()
var newCar: String = ""
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
cars = ["BMW","Audi", "Volkswagen"]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cars.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel?.text = cars[indexPath.row]
return cell
}
}

You forgot to register your controller as a dataSource for UITableView.
Add this to your code:
您忘记将控制器注册为 UITableView 的数据源。
将此添加到您的代码中：
@IBOutlet var myTableView: UITableView! {
didSet {
myTableView.dataSource = self
}
}

Maybe you forgot to add these two lines to your view controller's viewDidLoadmethod:
也许您忘记将这两行添加到您的视图控制器的viewDidLoad方法中：
yourTableView.delegate = self
yourTableView.dataSource = self

class SelectCategoryViewController: UIViewController {
@IBOutlet weak var tableView: UITableView!
var CategeryArray = ["Food","Travel","Lifestyle","Card","MyReserve","Game","Songs","Movies","Entertainment","Business","Education","Finance","Drink","Sports","Social","Shopping"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
self.tableView.dataSource = self
self.tableView.delegate = self
}
}
extension SelectCategoryViewController: UITableViewDelegate,UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return CategeryArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell")!
cell.textLabel?.text = self.CategeryArray[indexPath.row]
return cell
}
}
set the identifier =TableViewCellin Main.storyboard
And also set the class name for TableViewCell
在 Main.storyboard 中设置 identifier = TableViewCell
并为TableViewCell设置类名
