如何为选定的tableView行创建自定义图像复选标记附件？

Question

How can I assign a custom image and for the select and deselect .checkmark tableView accessory?

Is it possible to also position this custom accessory on the left side of the tableView row and have constantly visible in the tableView?

When the tableView first loads the accessory is still shown just deselected essentially similar to the Apple Reminders app.

Here is an example of what I am looking for:

Deselected:

Selected:

Currently, this is what I have:

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.cellForRow(at: indexPath)?.accessoryType = .checkmark
}

override func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
    tableView.cellForRow(at: indexPath)?.accessoryType = .none
}

Here is a sample code. You need to create your own accessory view for my case I Just added one circle inside a custom view.After that you just need to make hidden true or false.

extension ViewController: UITableViewDataSource, UITableViewDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 10
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
    cell.accessoryView = CheckMarkView.init()
    cell.accessoryView?.isHidden = true
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    //tableView.cellForRow(at: indexPath)?.accessoryType = .checkmark
    tableView.cellForRow(at: indexPath)?.accessoryView?.isHidden = false
}

func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
    tableView.cellForRow(at: indexPath)?.accessoryView?.isHidden = true
}

}

class CheckMarkView: UIView {
override init(frame: CGRect) {
    super.init(frame: frame) // calls designated initializer
    let img = UIImage(named: "circle.png") //replace with your image name
    let imageView: UIImageView = UIImageView(image: img)
    self.addSubview(imageView)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}
}
