Passing data to a custom UITableViewCell class

Question

ViewControllerA will be pushing to ViewControllerB. ViewcontrollerB is a UITableView that has a custom UITableViewCell that is registered upon load.

Here is my custom UITableViewCell:

override func awakeFromNib() {
        super.awakeFromNib()
    // Here is me attempting to pass my data from my view controller
    someButton.text = stringFromViewController
}

Here's my UITableView:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let customCell = CustomCell()
    customCell.stringFromViewController = "Some Text"
    self.performSegueWithIdentifier("ViewControllerB", sender: nil)    
}

Whenever I attempt this the string comes back as empty. I'm not sure if this has to do with the fact that I am trying to pass this data to the UITableViewCell instead of the UITableView that contains the custom cell. I'd like to pass the data to my custom cell class.

Answer 1

You going about this the wrong way. your tableView is reloading automatically upon loading controller B. you should pass the data to the cell in tableView:CellForRow: method. you can also call tableView.reloadData() once you assign the value from controller A. here's an example:

class ControllerB {
  var tableView: UITableView! //IBOutlet?
  var stringFromA: String? {
      didSet {
        self.tableView.reloadData()
      }
 }

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("UITableViewCell")
    cell.stringFromA = self.stringFromA
    return cell
}
