How to set tableview style to have subtitle programmatically while having dequeueReusableCell? - ios

Question

I want my tableView to have subtitle as well as being able to dequeue properly. I have referred to this link but it does not work for my code. What should I do?
My code is currently like this:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
//Calling tableview for a reusable cell here will always return a cell
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = developerArray[indexPath.row].developerName
cell.detailTextLabel?.text = developerArray[indexPath.row].developerHP
return cell
}

Answer 1

Swift 5
//Declare the variable cell Identifier
let reuseCellIdentifier = “cellIdentifier”;
//Implementation of cellForRowAt
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCell(withIdentifier: reuseCellIdentifier)
if (!(cell != nil)) {
cell = UITableViewCell(style: .subtitle, reuseIdentifier: reuseCellIdentifier)
}
cell?.textLabel?.text = //Title text
cell?.detailTextLabel?.text = //Subtitle text
return cell!
}

You can create custom cell using nib by adding labels
For creating custom cell refer this link:
Custom UITableViewCell from nib in Swift
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:MyCustomCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as! MyCustomCell
cell.title.text = yourTitleArray[indexPath.row]
cell.detailLbl.text = yourDetailArray[indexPath.row]
return cell
}

So first of all, did you create your table using storyboard or code?
Either way you need to make sure you set the datasource and delegate to self, provided the class they are in conforms to :
UITableViewDataSource
and
UITableViewDelegate
myTable?.delegate = self
myTable?.dataSource = self
Also make sure you register your cell
myTable?.register(myCell.self, forCellReuseIdentifier: "myCell")
And when declaring your cell, you need to force it as the type
let cell = tableView.dequeueReusableCell(withIdentifier: "myCell", for: indexPath) as! myCell
Below is a working sample of tableview with a created cell. I hope this helps.
import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
// Create the tableview object
var myTable:UITableView?
override func viewDidLoad() {
// Set the size and location of the tableview
myTable = UITableView(frame: CGRect(x: 0, y: 0, width: 300, height: 600))
// register your cell
myTable?.register(myCell.self, forCellReuseIdentifier: "myCell")
// set the background color of the table, note this wont make a difference unless the cell background is changed.
myTable?.backgroundColor = UIColor.clear
// set the datasource and delegate to self
myTable?.delegate = self
myTable?.dataSource = self
// This is jsut for style, wether there should be seperators or not, and if the user can select multiple lines
myTable?.separatorStyle = .none
myTable?.allowsMultipleSelection = true
// Add the table to your view
self.view.addSubview(myTable!)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// This is declaring how many rows you want in your table. I have 1 but you can do it according to the size of your array.
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// create the cell
let cell = tableView.dequeueReusableCell(withIdentifier: "myCell", for: indexPath) as! myCell
// set the title text for this cell
cell.title.text = "HelloWorld"
// return the cell
return cell
}
}
and this is the class for the cell we referenced above.
class myCell: UITableViewCell {
var title = UILabel()
var detail = UILabel()
override func awakeFromNib() {
super.awakeFromNib()
}
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
title.font = UIFont.boldSystemFont(ofSize: 16)
title.textAlignment = .center
self.contentView.addSubview(title)
self.contentView.addSubview(detail)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override func layoutSubviews() {
super.layoutSubviews()
title.frame = CGRect(x: self.contentView.frame.width / 2 - 200, y: 6, width: 400, height: 20)
detail.frame = CGRect(x: 150, y: 10, width: 280, height: 20)
}
}
Let me know if this helps. if you are doing it from story board let me know and I'll adjust.
