添加滑动删除 UITableViewCell

ios uitableview swift

我正在制作一个带有 UITableView 的 CheckList 应用程序。我想知道如何添加滑动以删除 UITableViewCell。

这是我的 ViewController.swift：

import UIKit

class ViewController: UIViewController,  UITextFieldDelegate, UITableViewDelegate,      UITableViewDataSource {

var tableView: UITableView!
var textField: UITextField!
var tableViewData:Array<String> = []

// Define Colors

let lightColor: UIColor = UIColor(red: 0.996, green: 0.467, blue: 0.224, alpha: 1)
let medColor: UIColor = UIColor(red: 0.973, green: 0.388, blue: 0.173, alpha: 1)
let darkColor: UIColor = UIColor(red: 0.800, green: 0.263, blue: 0.106, alpha: 1)
let greenColor: UIColor = UIColor(red: 0.251, green: 0.831, blue: 0.494, alpha: 1)

init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
    super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
    // Custom initialization
}

override func viewDidLoad() {
    super.viewDidLoad()

    //Set up table view

    self.tableView = UITableView(frame: CGRectMake(0, 100, self.view.bounds.size.width, self.view.bounds.size.height-100), style: UITableViewStyle.Plain)
    self.tableView.registerClass(MyTableViewCell.self, forCellReuseIdentifier: "myCell")
    self.tableView.backgroundColor = darkColor
    //self.tableView.separatorStyle = UITableViewCellSeparatorStyle.None
    self.tableView.delegate = self
    self.tableView.dataSource = self

    self.view.addSubview(self.tableView)

    //Set up text field

    self.textField = UITextField(frame: CGRectMake(0, 0, self.view.bounds.size.width, 100))
    self.textField.backgroundColor = lightColor
    self.textField.font = UIFont(name: "AvenirNext-Bold", size: 26)
    self.textField.delegate = self

    self.view.addSubview(self.textField)



}

//Table View Delegate

func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {

    return tableViewData.count

}

func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {

    var myNewCell: MyTableViewCell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath) as MyTableViewCell
    myNewCell.text = self.tableViewData[indexPath.row]

    return myNewCell

}

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {

    let mySelectedCell:UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)

    //Colors

    mySelectedCell.detailTextLabel.textColor = UIColor.whiteColor()
    mySelectedCell.tintColor = UIColor.whiteColor()

    //Setup Details / Date

    let myDate:NSDate = NSDate()
    var myDateFormatter:NSDateFormatter = NSDateFormatter()
    myDateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle

    mySelectedCell.detailTextLabel.text = myDateFormatter.stringFromDate(myDate)
    mySelectedCell.accessoryType = UITableViewCellAccessoryType.Checkmark
    mySelectedCell.backgroundColor = greenColor

}

override func prefersStatusBarHidden() -> Bool {
    return true

}

//Text Field Delegate

func textFieldShouldReturn(textField: UITextField!) -> Bool {

    tableViewData.append(textField.text)
    textField.text = ""
    self.tableView.reloadData()
    textField.resignFirstResponder()
    return true

}

}

这是 MyTableViewCell.swift：

import UIKit

class MyTableViewCell: UITableViewCell {

let medColor: UIColor = UIColor(red: 0.973, green: 0.388, blue: 0.173, alpha: 1)

init(style: UITableViewCellStyle, reuseIdentifier: String) {
    super.init(style: UITableViewCellStyle.Subtitle, reuseIdentifier: reuseIdentifier)

    self.textColor = UIColor.whiteColor()
    self.backgroundColor = medColor
    self.selectionStyle = UITableViewCellSelectionStyle.None
}

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}

}

我使用 iOS8 作为部署目标（不确定它会产生什么不同）。

请阅读“iOS 表视图编程指南”。有一整节是关于处理表视图删除的。您缺少几个必需的委托方法来使其工作。

仅供参考 - 您发布的一半代码与问题无关。请仅发布相关代码。

Giovanni Palusa

添加这两个函数：

func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
    return true
}

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if (editingStyle == UITableViewCellEditingStyle.Delete) {
        // handle delete (by removing the data from your array and updating the tableview)
    }
}

斯威夫特 3.0：

override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if (editingStyle == UITableViewCellEditingStyle.delete) {
        // handle delete (by removing the data from your array and updating the tableview)
    }
}

斯威夫特 4.2

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
    if (editingStyle == .delete) {
        // handle delete (by removing the data from your array and updating the tableview)
    }
}

新手 iOS 程序员在这里 - 有没有一种很好的方法来学习需要实现哪些方法来处理（看似）这样的基本功能？对于我的新手来说，文档似乎有点冗长且难以理解。

@datayeah 如果你想改变“删除”按钮文本，你可以重写这个函数， func tableView(tableView: UITableView, titleForDeleteConfirmationButtonForRowAtIndexPath indexPath: NSIndexPath) -> String? { //返回要在此处添加的文本 }

swift 3 代码缺少右大括号 }。我总共花了 5 分钟才弄清楚这一点：p

@lase 您可能想看一下名为 Dash 的应用程序。它使您能够搜索文档，并且比浏览网络要快得多。它还本地存储在您的计算机上，因此您无需访问网络即可查找内容。您还可以加载其他语言的文档。

@lase iOS API 充满了很多东西，几乎不可能全部了解。因此，听起来很陈词滥调，你从经验中学到了这样的东西。我已经做 iOS 6 年了，我和你一样在这里，因为我忘记了如何添加 Swipe to Delete :^)

你可以试试这个：

func tableView(tableView: UITableView!, canEditRowAtIndexPath indexPath: NSIndexPath!) -> Bool {
    return true
}

func tableView(tableView: UITableView!, commitEditingStyle editingStyle:   UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath!) {
    if (editingStyle == UITableViewCellEditingStyle.Delete) {
        NamesTable.beginUpdates()
        Names.removeAtIndex(indexPath!.row)
        NamesTable.deleteRowsAtIndexPaths([indexPath], withRowAnimation: nil)
        NamesTable.endUpdates()

    }
}

如果您支持 iOS11+，请参阅 discussion：

尽可能使用 performBatchUpdates(_:completion:) 方法而不是这个方法。

感谢beingUpdates()和endUpdates()。你不会经常看到它们，我只是看到它们是 WWDC 最佳实践演讲的一部分。

这次真是万分感谢！！ :D

另一种允许您在滑动单元格时更改“删除”文本并添加更多按钮的方法是使用 editActionsForRowAtIndexPath。

func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
    return true
}

func tableView(tableView: (UITableView!), commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: (NSIndexPath!)) {

}

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {

    var deleteAction = UITableViewRowAction(style: .Default, title: "Delete") {action in
       //handle delete
    }

    var editAction = UITableViewRowAction(style: .Normal, title: "Edit") {action in
        //handle edit
    }

    return [deleteAction, editAction]
}

canEditRowAtIndexPath 和 commitEditingStyle 仍然是必需的，但您可以将 commitEditingStyle 留空，因为删除是在 editActionsForRowAtIndexPath 中处理的。

必须将最后一个函数的签名更改为 func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]？谢谢！

@Crashalot 如果您的类继承自 UITableViewController 并且您正在覆盖此方法，那么是的，签名必须返回 [UITableViewRowAction]?。但是，当您不是从 UITableViewController 继承时，即该方法应返回 [AnyObject]?。以为我会弄清楚何时使用 which 所以任何阅读本文的人都不仅仅是在猜测。

这是 iOS11 和 Swift 4 中的新功能。

尾随滑动：

@available(iOS 11.0, *)
override 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 rename = UIContextualAction(style: .normal, title: "Edit") { (action, sourceView, completionHandler) in
        print("index path of edit: \(indexPath)")
        completionHandler(true)

用它：

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if editingStyle == UITableViewCellEditingStyle.Delete {
        langData.removeAtIndex(indexPath.row) //langData is array from i delete values
        tableView.deleteRowsAtIndexPaths([indexPath],  withRowAnimation: UITableViewRowAnimation.Automatic)
    }
}

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let Approve = UITableViewRowAction(style: .normal, title: "Approve") { action, index in

        self.ApproveFunc(indexPath: indexPath)
    }
    Approve.backgroundColor = .green

    let Reject = UITableViewRowAction(style: .normal, title: "Reject") { action, index in

        self.rejectFunc(indexPath: indexPath)
    }
    Reject.backgroundColor = .red



    return [Reject, Approve]
}

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

func ApproveFunc(indexPath: IndexPath) {
    print(indexPath.row)
}
func rejectFunc(indexPath: IndexPath) {

}

“UITableViewRowAction”在 iOS 13 中已弃用。您需要改用“UIContextualAction”！

Swift 4 -- @available(iOS 11.0, *)

    let edit = UIContextualAction(style: .normal, title: "") { (action, view, nil) in
        let refreshAlert = UIAlertController(title: "Deletion", message: "Are you sure you want to remove this item from cart? ", preferredStyle: .alert)

        refreshAlert.addAction(UIAlertAction(title: "Yes", style: .default, handler: { (action: UIAlertAction!) in

        }))

        refreshAlert.addAction(UIAlertAction(title: "No", style: .default, handler: { (action: UIAlertAction!) in
            refreshAlert .dismiss(animated: true, completion: nil)
        }))

从 Xcode 6.1.1 开始，Dash 的答案有一些微小的变化。

override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
        return true
    }

    override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if (editingStyle == UITableViewCellEditingStyle.Delete) {
            // handle delete (by removing the data from your array and updating the tableview)
        }
    }

斯威夫特 3：

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if (editingStyle == UITableViewCellEditingStyle.delete) {
        // delete data and row
        dataList.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .fade)
    }
}

知道如何将删除按钮更改为取消吗？

如果你想改变“删除”按钮的文字，你可以重写这个函数，func tableView(tableView: UITableView, titleForDeleteConfirmationButtonForRowAtIndexPath indexPath: NSIndexPath) -> String? { //返回您要在此处添加的文本 } #Rachel

支持自定义标题的 Swift 3

        func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
                return true
            }

    //If you want to change title
            func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String? {
                return "Cancel"
            }

            func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
                if (editingStyle == UITableViewCellEditingStyle.delete) {
// you might want to delete the item at the array first before calling this function
                    tableView.deleteRows(at: indexPath, with: .automatic)
                }
            }

在 Swift 2.0 中为我工作

override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
    return true
}

override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {

}

override func tableView(tableView: UITableView,
    editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
    let block = UITableViewRowAction(style: .Normal, title: "Block") { action, index in
        print("Block")
        self.removeObjectAtIndexPath(indexPath, animated: true)
    }
    let delete = UITableViewRowAction(style: .Default, title: "Delete") { action, index in
        print("Delete")
        self.removeObjectAtIndexPath(indexPath, animated: true)
    }
    return [delete, block]
}

您能否详细说明 "Block" 的作用？

Pratik Lad

在 Swift 4 tableview 中添加，滑动删除 UITableViewCell

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .destructive, title: "delete") { (action, indexPath) in
        // delete item at indexPath

    }
    return [delete]
}

由于 UITableViewRowAction 在 iOS 13.0 中已弃用，因此您可以使用 UISwipeActionsConfiguration

   func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let deleteAction = UIContextualAction(style: .destructive, title: "Delete") {  (contextualAction, view, boolValue) in
            self.deleteData(at: indexPath)
        }

        let editAction = UIContextualAction(style: .normal, title: "Edit") {  (contextualAction, view, boolValue) in
            self.editData(at: indexPath)
        }
        editAction.backgroundColor = .purple
        let swipeActions = UISwipeActionsConfiguration(actions: [deleteAction,editAction])

        return swipeActions
    }

    func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
    }

    func deleteData(at indexPath: IndexPath) {
        print(indexPath.row)
    }

    func editData(at indexPath: IndexPath) {
        print(indexPath.row)
    }

假设您的数据数组是“数据”，只需添加这些

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if (editingStyle == UITableViewCellEditingStyle.delete) {
        // handle delete (by removing the data from your array and updating the tableview)
        if let tv=table
        {



            data.remove(at: indexPath.row)
            tv.deleteRows(at: [indexPath], with: .fade)



        }
    }
}

Xcode 要求 UIContextualAction，这对我来说对更新版本有用：

对于尾随滑动操作：->

 func delete(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
        let company = companies[indexPath.row]
        let action = UIContextualAction(style: .destructive, title: "Delete") { (action, view, _) in
           // Perform Delete Action
        }
        return action
    }
    
    func edit(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
        let action  = UIContextualAction(style: .normal, title: "Edit") { (action, view, escaping) in
            // Perform Edit Action
        }
        return action
    }
    
    override func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let delete = self.delete(forRowAtIndexPath: indexPath)
        let edit = self.edit(forRowAtIndexPath: indexPath)
        let swipe = UISwipeActionsConfiguration(actions: [delete, edit])
        return swipe
    }

对于领先的滑动操作：->

 func delete(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
        let company = companies[indexPath.row]
        let action = UIContextualAction(style: .destructive, title: "Delete") { (action, view, _) in
           // Perform Delete Action
        }
        return action
    }
    
    func edit(forRowAtIndexPath indexPath: IndexPath) -> UIContextualAction {
        let action  = UIContextualAction(style: .normal, title: "Edit") { (action, view, escaping) in
            // Perform Edit Action
        }
        return action
    }
    
    override func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let delete = self.delete(forRowAtIndexPath: indexPath)
        let edit = self.edit(forRowAtIndexPath: indexPath)
        let swipe = UISwipeActionsConfiguration(actions: [delete, edit])
        return swipe
    }

为 tableView 委托的 canEditRowAt 返回 true：->

override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
    }
