how to create single selection check box in swift2?

Question

import UIKit

class CheckBox: UIButton {
    // Images
    let checkedImage = UIImage(named: "check-sign.png")! as UIImage
    let uncheckedImage = UIImage(named: "blank-square.png")! as UIImage

    // Bool property
    var isChecked: Bool = false {
        didSet{
            if isChecked == true {
                self.setImage(checkedImage, forState: .Normal)
            } else {
                self.setImage(uncheckedImage, forState: .Normal)
            }
        }
    }

    override func awakeFromNib() {
        self.addTarget(self, action: "buttonClicked:", forControlEvents: UIControlEvents.TouchUpInside)
        self.isChecked = false
    }

    func buttonClicked(sender: UIButton) {
        if sender == self {
            isChecked = !isChecked
        }
    }
}

I was trying to implement checkboxes in Swift 2. I was referring to How to create radio buttons and checkbox in swift (iOS)? .

But my requirement is I want to implement single selection checkbox. I am not sure how to group the buttons via IB to make it single selectable.

Any suggestion?

Currently it is multiple selectable, I want to make it single selectable.

Answer 1

You can do it with UITableView and custom cells ,and change tableView.allowsMultipleSelection = flase.

Ex : You can do that by setting the accessoryType on the selected UITableViewCell instances to UITableViewCelAccessoryCheckmark.

To deselect the row, set it back to UITableViewCellAccessoryNone.
