SwipeActions 在 tableView swift 5 xcode 13.4.1 中不起作用

Question

我正在對我的 tableview 進行 trailingSwipe，但它不起作用。 不調用 function trailingSwipeActionsConfigurationForRowAt 。

嘗試使用leadingSwipeActionsConfigurationForRowAt ，如果它對我有用，但不適用於trailingSwipe

有效，我有委托和數據源表視圖

代碼

 func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? { let delete = UIContextualAction(style: .normal, title: "delete2") {(action, view, completionHandler) in print("delete2 \(indexPath.row)") } let swipe = UISwipeActionsConfiguration(actions: [delete]) return swipe }

使用 Apple Mac M1 ( MacBook Pro M1)

Answer 1

我也遇到了這個問題。 也許這個問題與Apple Mac M1有關，請嘗試使用Apple intel 。

請檢查這個問題

下面的代碼在我的 Apple Intel 中運行良好。

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let action = UIContextualAction(style: .destructive, title: "REMOVE") { [self] action, view, completion in
            // Your swipe action code!
            completion(true)
        }
    
    action.backgroundColor = UIColor.red
    
    let swipeAction = UISwipeActionsConfiguration(actions: [action])
    swipeAction.performsFirstActionWithFullSwipe = false        // Full swipe disable
    
    return swipeAction
}

試試這個，在 Xcode 13+、Apple Mac M1 和 Swift 5 上運行良好

 func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
} 
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {}

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let delete = UIContextualAction(style: .destructive, title: "Delete") { (action, sourceView, completionHandler) in
      //  print("index path of delete: \(indexPath)")
        
        completionHandler(true)
    }
    let edit = UIContextualAction(style: .normal, title: "Edit") { [weak self] (action, sourceView, completionHandler)  in
        
        completionHandler(true)
    }
    delete.title = ""
    delete.image = UIImage(named: "deleteProfile")
    
    edit.title = ""
    edit.image = UIImage(named: "editProfile")
    
    let swipeAction = UISwipeActionsConfiguration(actions: [delete,edit])
    swipeAction.performsFirstActionWithFullSwipe = false // This is the line which disables full swipe
    return swipeAction
}
