UIBarButtonItem action not work UITableView cell

问题

I create UIBarbUttonItem inside UITableView cell programmatically like this :

func setupChildrenPicker(){
    let chooseButton = UIBarButtonItem(title: Wordings.BTN_CHOOSE, style: UIBarButtonItemStyle.done, target: nil, action: #selector(self.pickerChildrenDonePressed))
}

func pickerChildrenDonePressed(){
    print ("pickerChildrenDonePressed")
}

override func awakeFromNib() {
    super.awakeFromNib()
    setupChildrenPicker()
}

but when I click that BarButtonItem, it not called pickerChildrenDonePressed() function (did not create log pickerChildrenDonePressed).

What is the correct code to make it called pickerChildrenDonePressed?

Use this :

Inside

UIBarButtonItem(title: Wordings.BTN_CHOOSE, style:UIBarButtonItemStyle.done, target: nil, action: #selector(self.pickerChildrenDonePressed)

change target to self instead of nil
