刷卡动作延迟

Question

我已经加入刷卡行动，我的应用程序。我有5个按键代表星期几。当我点击一个按钮，它改变了我的表视图和一些事情的阵列。刷卡动作不完全一样的伟大工程，但在刷卡有时冻结，并在几秒钟后再次工作。它的潜伏期。

override func viewDidLoad() {
    super.viewDidLoad()

    let rightSwipe = UISwipeGestureRecognizer(target: self, action: #selector(actionSwipeRight))
    rightSwipe.direction = .right

    let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(actionSwipeLeft))
    leftSwipe.direction = .left

    view.addGestureRecognizer(rightSwipe)
    view.addGestureRecognizer(leftSwipe)
}

而刷卡码

// s'éxécute lorsque qu'un swipe vers la droite est effectué
@objc private func actionSwipeRight() {
    print("swipe right")

    switch self.selectedDayinHoraire {
        case "LUNDI" :
            return
        case "MARDI" :
            changeDay(for: "LUNDI")
        case "MERCREDI" :
           changeDay(for: "MARDI")
        case "JEUDI" :
            changeDay(for: "MERCREDI")
        case "VENDREDI" :
            changeDay(for: "JEUDI")
        default: break
    }
}

// s'éxécute lorsque qu'un swipe vers la gauche est effectué
@objc private func actionSwipeLeft() {
    print("swipe left")

    switch self.selectedDayinHoraire {
        case "LUNDI" :
           changeDay(for: "MARDI")
        case "MARDI" :
           changeDay(for: "MERCREDI")
        case "MERCREDI" :
            changeDay(for: "JEUDI")
        case "JEUDI" :
            changeDay(for: "VENDREDI")
        case "VENDREDI" :
            return
        default: break
    }
}

func changeDay(for day : String) {
    switch day {
        case "LUNDI" :
                self.menuSelectionné(btn: self.btnLundi)
                self.LabelDynamiqueJour.text = " horaire du lundi"
                self.selectedDayinHoraire = "LUNDI"
        case "MARDI" :
                self.menuSelectionné(btn: self.btnMardi)
                self.LabelDynamiqueJour.text = " horaire du Mardi"
                self.selectedDayinHoraire = "MARDI"
        case "MERCREDI" :
                self.menuSelectionné(btn: self.btnMercredi)
                self.LabelDynamiqueJour.text = " horaire du Mercredi"
                self.selectedDayinHoraire = "MERCREDI"
        case "JEUDI" :
                self.menuSelectionné(btn: self.btnJeudi)
                self.LabelDynamiqueJour.text = " horaire du Jeudi"
                self.selectedDayinHoraire = "JEUDI"
        case "VENDREDI" :
                self.menuSelectionné(btn: self.btnVendredi)
                self.LabelDynamiqueJour.text = " horaire du vendredi"
                self.selectedDayinHoraire = "VENDREDI"
        default: break
    }
    tableviewHoraire.reloadData()
}

按钮操作：

@IBAction func btnLun(_ sender: UIButton) {
    changeDay(for: "LUNDI")
}

@IBAction func btnMar(_ sender: UIButton) {
   changeDay(for: "MARDI")
}

@IBAction func btnMer(_ sender: UIButton) {
   changeDay(for: "MERCREDI")
}

@IBAction func btnJeu(_ sender: UIButton) {
   changeDay(for: "JEUDI")
}

@IBAction func btnVen(_ sender: UIButton) {
   changeDay(for: "VENDREDI")
}

你可以看到刷卡的动作做同样的，但有时它冻结，自己测试一下，如果你想，这个问题是来自Horaire视图。 https://github.com/CedricLnx/School-Companion

Answer 1

设置你的Horaire类作为UIGestureRecognizerDelegate的子类。

class Horaire: ViewController, UITableViewDataSource, UITableViewDelegate, UIGestureRecognizerDelegate {

每刷卡的委托设置为self。

    let rightSwipe = UISwipeGestureRecognizer(target: self, action: #selector(actionSwipeRight))
    rightSwipe.direction = .right
    rightSwipe.delegate = self

    let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(actionSwipeLeft))
    leftSwipe.direction = .left
    leftSwipe.delegate = self

添加UIGestureRecognizerDelegate功能。

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
}

作为Apple Docs shouldRecognizeSimultaneouslyWith解释允许两个或多个手势以在Sametime工作。在这种情况下，它应该允许一个单一的触摸被注册为self.view轻扫，以及对的tableView。
