在目标操作案例中秘密调用PerformSelector？

Question

在这个例子中，我传递给选择器的函数是通过秘密调用performSelector来调用的吗？

let gestureRecognizer = UIPanGestureRecognizer(target: self, action: #selector(actionGesture(gesture: )))
    self.view.addGestureRecognizer(gestureRecognizer)
}

@objc func actionGesture(gesture: UIPanGestureRecognizer){
....
}
