Swift tableView cell set accessory type

Question

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    @IBOutlet
    var tableView: UITableView
    var items: String[] = ["We", "Heart", "Swift"]

    override func viewDidLoad() {
        super.viewDidLoad()
        self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "myCell")
    }


    func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {
        return self.items.count;
    }

    func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {

        var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("myCell") as UITableViewCell

        cell.textLabel.text = self.items[indexPath.row]
        cell.accessoryType = UITableViewCellAccessoryType.DetailDisclosureButton
        cell.selectionStyle = UITableViewCellSelectionStyle.Blue
        tableView.separatorStyle = UITableViewCellSeparatorStyle.None
        return cell
    }

    func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
        println("You selected cell #\(indexPath.row)!")

    }
}

My problem is that the accessoryType and the selectionStyle don't get changed. The tableView.separatorStyle does get changed as well as the cell.textlabel.text. How can I fix that?

Answer 1

UITableViewCell.SelectionStyle.blue

The cell has a default background color when selected.

In iOS 7, the selection color is no longer blue. Use UITableViewCell.SelectionStyle.default instead.

As for the accessoryType, it should work fine as long as you don't change it later somewhere else. Make sure that the table width is correct, otherwise accessory views might be offscreen.

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    @IBOutlet
    var tableView: UITableView

    var items: String[] = ["We", "Heart", "Swift"]

    override func viewDidLoad() {
        super.viewDidLoad()
        self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "myCell")
    }


    func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {
        return self.items.count;
    }

    func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {

        var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("myCell") as UITableViewCell
        cell.textLabel.text = self.items[indexPath.row]
        cell.selectionStyle = UITableView.CellSelectionStyle.blue

        /*
        enum UITableViewCellAccessoryType : Int {
        case none // don't show any accessory view
        case disclosureIndicator // regular chevron. doesn't track
        case detailDisclosureButton // info button w/ chevron. tracks
        case checkmark // checkmark. doesn't track
        case detailButton // info button. tracks
        }
        */

        // Standard options
        cell.accessoryType = UITableViewCell.AccessoryType.none
        cell.accessoryType = UITableViewCell.AccessoryType.disclosureIndicator
        cell.accessoryType = UITableViewCell.AccessoryType.detailDisclosureButton
        cell.accessoryType = UITableViewCell.AccessoryType.checkmark
        cell.accessoryType = UITableViewCell.AccessoryType.detailButton

        // Custom view options
        cell.accessoryType = UITableViewCell.AccessoryType.none
        cell.accessoryView = UIView(frame: CGRectMake(0, 0, 20, 20))
        cell.accessoryView.backgroundColor = UIColor.blueColor()

        return cell
    }

    func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
        println("You selected cell #\(indexPath.row)!")

    }
}

Note that it isn't a good solution to set separatorStyle of the table each time the cell is requested, instead do it once when the tableView is loaded: at viewDidLoad.

Answer 2

I didn't have any luck setting it in the cellForRowAtIndexPath method, moving it to willDisplayCell fixed the issue with it not showing up.

override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    cell.accessoryType = .DisclosureIndicator
}
