Fügen Sie das Wischen hinzu, um UITableViewCell zu löschen

Ich mache eine CheckList-Anwendung mit einem UITableView. Ich habe mich gefragt, wie man einen Swipe hinzufügt, um ein UITableViewCell zu löschen.

Das ist mein 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

}

}

Und das ist 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
}

}

Ich verwende iOS8 als Bereitstellungsziel (nicht sicher, welchen Unterschied es machen wird).

Fügen Sie diese beiden Funktionen hinzu:

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)
    }
}

Swift 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)
    }
}

Swift 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)
    }
}

Eine andere Möglichkeit, den Text von "Delete" zu ändern und beim Verschieben einer Zelle weitere Schaltflächen hinzuzufügen, ist 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 und commitEditingStyle sind noch erforderlich, Sie können jedoch commitEditingStyle leer lassen, da das Löschen in editActionsForRowAtIndexPath erfolgt.

Sie können dies versuchen:

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()

    }
}

VARUN SINGHAL

benutze es :

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)
    }
}

hoffe es hilft dir

Funktioniert für mich in Swift 2.0

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]

Seit Xcode 6.1.1 gibt es einige kleine Änderungen an der Antwort von Dash.

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) {

Streichen Sie in Swift 4 tableview add, um UITableViewCell zu löschen

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

    }
    return [delete]
}

Ich habe tableViewCell verwendet, um mehrere Daten anzuzeigen, nachdem swipe () von rechts nach links in einer Zelle zwei Schaltflächen anzeigt. Genehmigen und ablehnen Es gibt zwei Methoden, die erste ist ApproveFunc, die ein Argument akzeptiert, und die andere ist RejectFunc, die auch nimmt ein Argument.  enter image description here 

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) {

Einfach Methode hinzufügen:

    let delete = UITableViewRowAction(style: UITableViewRowActionStyle.destructive, title: "Delete") { (action, indexPath) in
        self.arrayFruit.remove(at: indexPath.row)
        self.tblList.reloadData()
    }

    let edit = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Edit") { (action, indexpath) in

        let alert = UIAlertController(title: "FruitApp", message: "Enter Fuit Name", preferredStyle: UIAlertControllerStyle.alert)
        alert.addTextField(configurationHandler: { (textField) in
            textField.placeholder = "Enter new fruit name"
        })
        alert.addAction(UIAlertAction(title: "Update", style: UIAlertActionStyle.default, handler: { [weak alert](_) in
            let textField = alert?.textFields![0]
            self.arrayFruit[indexPath.row] = (textField?.text!)!

fügen Sie einfach diese .__ hinzu, vorausgesetzt, Ihr Datenarray ist 'data'.

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)
