Question

当我选择任何行而不是调用时，没有被调用。它的颜色在选择时也会变为蓝色。但didSelect不工作.Delegate，DataSources和Table outlet也相连。这是我的代码：

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    categoryLbl.text = categoryArray[indexPath.row].type
    dataDict.setValue(categoryArray[indexPath.row].type, forKey: "category")
    categoryTable?.isHidden = true
}

override func viewDidLoad() {
    super.viewDidLoad()

    imagePicker.delegate = self
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardNotification(notification:)), name: NSNotification.Name.UIKeyboardWillChangeFrame, object: nil)
    categoryTable?.isHidden = true

    self.geCategoryData()

    let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action:#selector(AddFeedbackViewController.dismissKeyboard))
    view.addGestureRecognizer(tap)

}

Answer 1

试试这个，它会解决你的问题

tap.delegate = self // add this in viewdidLoad()

extension YourViewContoller: UIGestureRecognizerDelegate {

    func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {
        if touch.view != nil && touch.view!.isDescendantOfView(self.tableView) {
            return false
        }
        return true
    }
}

Answer 2

试试这个，

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

categoryLbl.text = categoryArray[indexPath.row].type
    dataDict.setValue(categoryArray[indexPath.row].type, forKey: "category")
    categoryTable?.isHidden = true

}

UITableView didSelect无法在swift 3.0中运行
