スワイプを追加して削除しますUITableViewCell

UITableViewを使ってCheckListアプリケーションを作成しています。スワイプを追加してUITableViewCellを削除する方法を考えていました。

これは私のViewController.Swiftです:

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

}

}

そしてこれはMyTableViewCell.Swiftです。

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
}

}

私は展開ターゲットとしてiOS8を使用しています(それがどのような違いをもたらすのかはっきりしません)。

これら二つの機能を加えなさい:

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)
    }
}

これを試すことができます:

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()

    }
}

セルをスライドさせるときに「削除」のテキストを変更してボタンを追加できるもう1つの方法は、editActionsForRowAtIndexPathを使用することです。

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]
}

canEditRowAtIndexPathcommitEditingStyleはまだ必要ですが、削除はcommitEditingStyleで処理されるため、editActionsForRowAtIndexPathを空のままにすることができます。

これを使って :

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)
    }
}

お役に立てば幸いです

末尾スワイプ:

複数のデータを表示するためにtableViewCellを使用しました。セル上で右から左にスワイプ()した後、2つのボタンが表示されます。Approve And reject。一つの引数を取ります。 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)

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