Trouble passing data from TableViewCell labels to a ViewController - xcode

Question

I am trying to pass data from the selected cell of an "Events" table view, to a "Details" View Controller. I have looked at various questions similar to mine, but I can't seem to properly apply it to my code. I also used labels, instead of a Subtitle style. There is also an image that needs to be passed.
my view controller looks like this:
import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet var tableView: UITableView!
var names = ["BTown Diner", "Dunnkirk", "Chocolate Mousse", "Lil Wayne", "Annie", "Campus Squad Social"]
var details = ["Free drink with meal after 12 AM", "LADIES drink free", "10% off all ice cream!", "Lil 500 concert", "an IU Theater Production", "Bring your Squad to the Campus Squad Social"]
var images = [UIImage(named: "btown"), UIImage(named: "dunn"), UIImage(named: "choco"), UIImage(named: "lilwayne"), UIImage(named: "default"), UIImage(named: "default")]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return names.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = self.tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomCell
cell.name.text = names[indexPath.row]
cell.detail.text = details[indexPath.row]
cell.photo.image = images[indexPath.row]
return cell
}
var valueToPass:String!
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
println("You selected cell #\(indexPath.row)!")
// Get Cell Label
let indexPath = tableView.indexPathForSelectedRow();
let currentCell = tableView.cellForRowAtIndexPath(indexPath!) as UITableViewCell!;
valueToPass = currentCell.textLabel.text
performSegueWithIdentifier("detailsSegue", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "detailsSegue") {
// initialize new view controller and cast it as your view controller
var viewController = segue.destinationViewController as detailsViewController
// your new view controller should have property that will store passed value
viewController.passedValue = valueToPass
}
}
}
and here is my customCell.swift file:
import UIKit
class CustomCell: UITableViewCell {
#IBOutlet var photo: UIImageView!
#IBOutlet var name: UILabel!
#IBOutlet var detail: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
I am very new to Swift, and it has proven to be very challenging for me. I'm really not a coder, however a project demands that I complete some of the coding for an application that I am the UI/UIX designer of. Thank you for your help in advance!

Answer 1

Try to register your "CustomCell" with the name "cell"
override func viewDidLoad() {
super.viewDidLoad()
tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "cell")
}

Here is a slight variation on your code starting with the main view controller...
import UIKit
class EventTableViewController: UITableViewController, UITableViewDataSource, UITableViewDelegate {
var names = ["BTown Diner", "Dunnkirk", "Chocolate Mousse", "Lil Wayne", "Annie", "Campus Squad Social"]
var details = ["Free drink with meal after 12 AM", "LADIES drink free", "10% off all ice cream!", "Lil 500 concert", "an IU Theater Production", "Bring your Squad to the Campus Squad Social"]
var images = [UIImage(named: "btown"), UIImage(named: "dunn"), UIImage(named: "choco"), UIImage(named: "lilwayne"), UIImage(named: "default"), UIImage(named: "default")]
override func viewDidLoad() {
super.viewDidLoad()
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return names.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = self.tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomCell
cell.name.text = names[indexPath.row]
cell.detail.text = details[indexPath.row]
cell.photo.image = images[indexPath.row]
return cell
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "detailsSegue" {
guard let eventVC = segue.destinationViewController as? DetailsViewController,
let eventIndex = tableView.indexPathForSelectedRow?.row else {
return
}
eventVC.eventName = names[eventIndex]
eventVC.eventDetail = details[eventIndex]
eventVC.eventPhoto = images[eventIndex]
}
}
}
and then a sample detailsViewController...
import UIKit
class DetailsViewController: UIViewController {
var eventName: String = ""
var eventDetail: String = ""
var eventPhoto: UIImage!
override func viewDidLoad() {
super.viewDidLoad()
print(eventName)
print(eventDetail)
}
}
You were off to a good start. Hope this helps get you the rest of the way.
