ios - didSelectRowAt 仅在多点触控时调用

Question

什么可以让 UITableViewCell 只检测多点触控？如果我用一根手指点击，它不会调用 didSelectRowAtIndex。

这是我的代码:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "bookingSettingsCell", for: indexPath) as! SettingsTableViewCell
    if indexPath.row < 3 {
        cell.settingSwitch.removeFromSuperview()
    }
    cell.settingTitle.text = dataForSetting[indexPath.row].first
    if dataForSetting[indexPath.row].last != "Pencil" {
        cell.settingValue.isHidden = true
        cell.settingChangable.isHidden = true
        cell.settingSwitch.isHidden = false
    }
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    DispatchQueue.main.async(execute: {
        if indexPath.row < 3 {
            let destinationVC = self.storyboard?.instantiateViewController(withIdentifier: "DatePicker") as! DatePickerViewController
            destinationVC.modalPresentationStyle = .overCurrentContext
            destinationVC.delegate = self
            self.present(destinationVC, animated: true, completion: nil)
        }
    })
}

UITableViewCell 类:

class SettingsTableViewCell: UITableViewCell {
@IBOutlet var settingTitle: UILabel!
@IBOutlet var settingChangable: UIImageView!
@IBOutlet var settingValue: UILabel!
@IBOutlet var settingSwitch: UISwitch!

    override func awakeFromNib() {
        super.awakeFromNib()
        settingSwitch.transform = CGAffineTransform(scaleX: 0.65, y: 0.60)
    }
}

在实现手势识别器的委托(delegate)方法后，您可以处理 uitableviews 的 didSelectRowAt 方法的行为。这可以防止 uiview 和 tableViewCell 之间点击的未定义行为，并保留触摸记录。

UIGestureRecognizerDelegate 方法:

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {
    println("in shouldReceiveTouch")
    gestureRecognizer.delegate = self
    if (touch.view == tableView){
        println("touching tableView list")
        return false
    }
    else{
        println("touching elsewhere")
        return true
    }
}
