從另一個 function 調用leadingSwipeActionsConfigurationForRowAt

Question

一個不尋常的問題，我有一個 UITableViewCell 有前導和尾隨滑動動作，

有沒有辦法從另一個調用一個？

例如，用戶滑動單元格並出現前導動作，單擊它時，將出現尾隨動作。

如附圖所示

當用戶滑動時，單元格的前緣會出現一個圖標，一旦點擊，就會出現尾部動作，並帶有一個刪除單元格的確認按鈕。

這有可能實現嗎？

這是我的代碼：

    func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let leadingAction = UIContextualAction(style: .normal, title: "", handler: { (leadingAction, view, completionHandler) in
        // Action here
        completionHandler(true)
    })

    if let deleteImage =  UIImage(named: "Delete")?.cgImage {
         leadingAction.image = ImageWithoutRender(cgImage: deleteImage, scale: UIScreen.main.nativeScale, orientation: .up)
    }

    let preventFullSwipe = UISwipeActionsConfiguration(actions: [leadingAction])
    preventFullSwipe.performsFirstActionWithFullSwipe = false


    leadingAction.backgroundColor = Colors.clearAlpha
    let configuration = UISwipeActionsConfiguration(actions: [leadingAction])
    return configuration
}

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let trailingAction = UIContextualAction(style: .normal, title: "", handler: { (trailingAction, view, completionHandler) in
        // Action here
        completionHandler(true)
    })

    if let deleteImage =  UIImage(named: "ComfirmDelete")?.cgImage {
         trailingAction.image = ImageWithoutRender(cgImage: deleteImage, scale: UIScreen.main.nativeScale, orientation: .up)
    }

    trailingAction.backgroundColor = Colors.clearAlpha
    let configuration = UISwipeActionsConfiguration(actions: [trailingAction])
    return configuration
}

Answer 1

您可以通過在尾隨動作完成塊中添加以下行來模擬滑動手勢

let gesture = UIPanGestureRecognizer()
gesture.setTranslation(CGPointMake(0, 100), inView: youtableViewCell)
wasDragged(gesture)

進一步的行為。

func wasDragged (gesture: UIPanGestureRecognizer) {        
    let translation = gesture.translationInView(youtableViewCell)
    let cell = gesture.view!

    // Move the object depending on the drag position
    cellcontentView.center = CGPoint(x: self.view.bounds.width / 2 + translation.x,
                              y:  self.view.bounds.height / 2 + translation.y)
}

注意：它可能不是一個完美的解決方案，但你可以讓它工作你現在有一個指南:)
