Sto facendo una domanda CheckList con a UITableView. Mi chiedevo come aggiungere un colpo per eliminare a UITableViewCell.
Questo è il mio 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
}
}E questo è 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
}
}Sto usando iOS8 come destinazione di distribuzione (non sono sicuro della differenza che farà).

Leggere la "Guida alla programmazione della vista tabella per iOS". C'è un'intera sezione sulla gestione delle eliminazioni della vista tabella. Mancano diversi metodi delegati richiesti per farlo funzionare.

rmaddy,
Cordiali saluti - metà del codice che hai pubblicato è irrilevante per la domanda. Si prega di inviare solo il codice pertinente.
