ios - 为什么我的#selector 不工作？

Question

我有一个函数:

 @objc func handleLongPress(data: SkelbimasModel, _ gestureRecognizer:UIGestureRecognizer){
    if gestureRecognizer.state != .began{
        return
    }

    let touchPoint:CGPoint = gestureRecognizer.location(in: self.Map)
    let touchMapCoordinate:CLLocationCoordinate2D =
        self.Map.convert(touchPoint, toCoordinateFrom: self.Map)

    let annot:MKPointAnnotation = MKPointAnnotation()
    annot.coordinate = touchMapCoordinate

    self.resetTracking()
    self.Map.addAnnotation(annot)
    skelbimai.append(annot)
    print(skelbimai)
    self.Map.removeGestureRecognizer(gestureRecognizer)
    Label.isHidden = true
}

我的 SkelbimbasModel 继承了 NSObject :

类 SkelbimasModel:NSObject {...}

而且那个函数没有被调用:

func addLongPressGesture(){
    let longPressRecogniser:UILongPressGestureRecognizer = UILongPressGestureRecognizer(target:self , action:#selector(ViewController.handleLongPress(data:_:)))
    longPressRecogniser.minimumPressDuration = 0.5 //user needs to press for 1 seconds
    self.Map.addGestureRecognizer(longPressRecogniser)
}

当我从函数中删除 SkelbimasModel 属性时，例如:

@objc func handleLongPress(_ gestureRecognizer:UIGestureRecognizer)

工作正常。如何向选择器声明函数，以传递 SkalbimasModel 属性？

Answer 1

选择器签名必须是以下之一。

@IBAction func myActionMethod()
@IBAction func myActionMethod(_ sender: UIGestureRecognizer)

官方文档

A gesture recognizer has one or more target-action pairs associated with it. If there are multiple target-action pairs, they are discrete, and not cumulative. Recognition of a gesture results in the dispatch of an action message to a target for each of the associated pairs. The action methods invoked must conform to one of the following signatures:

@IBAction func myActionMethod()

@IBAction func myActionMethod(_ sender: UIGestureRecognizer)

如果不想区分 View ，可以查看 View 标签。

let tag = gestureRecognizer.view?.tag
