When I click the right UITabButtonItem i want to add deleteButton to my table view and delete the rows when i click it. But i don't know how to do this. In each time i get errors.
import UIKit
class CustomCell: UITableViewCell {
@IBOutlet weak var label: UILabel!
@IBOutlet weak var view: UIView!
var gesture: Bool!
override func awakeFromNib() {
super.awakeFromNib()
var leftSwipe = UISwipeGestureRecognizer(target: self, action: Selector("handleSwipes:"))
var rightSwipe = UISwipeGestureRecognizer(target: self, action: Selector("handleSwipes:"))
leftSwipe.direction = .Left
rightSwipe.direction = .Right
self.addGestureRecognizer(leftSwipe)
self.addGestureRecognizer(rightSwipe)
gesture = false;
}
func handleSwipes(sender:UISwipeGestureRecognizer) {
if (gesture == false){
if (sender.direction == .Left) {
gesture = true;
var labelPosition = CGPointMake(self.view.frame.origin.x - 55.0, self.view.frame.origin.y);
UIView.animateWithDuration(0.5, animations: {
self.view.frame = CGRectMake( labelPosition.x , labelPosition.y , self.view.frame.size.width, self.view.frame.size.height)
}, completion: { (value: Bool) in
self.gesture = false;
})
}
if (sender.direction == .Right) {
gesture = true;
var viewPosition = CGPointMake(self.view.frame.origin.x + 55.0, self.view.frame.origin.y);
UIView.animateWithDuration(0.5, animations: {
self.view.frame = CGRectMake( viewPosition.x , viewPosition.y , self.view.frame.size.width, self.view.frame.size.height)
}, completion: { (value: Bool) in
self.gesture = false;
})
}
}
}
func buttonClick(sender : UIButton) {
let deleteButton = UIButton.buttonWithType(UIButtonType.System) as UIButton
let image = UIImage(named: "delete") as UIImage?
deleteButton.frame = CGRectMake(0, 0, 51, 46)
deleteButton.setImage(image, forState: .Normal)
deleteButton.backgroundColor = UIColor.redColor()
deleteButton.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(deleteButton)
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
func setCell(labeltext :String)
{
self.label.text = labeltext
}
}
here is my view controller
class controller: UIViewController, UITableViewDelegate, UITableViewDataSource {
var arrayOfList: [List] = [List]()
override func viewDidLoad() {
super.viewDidLoad()
var editButton : UIBarButtonItem = UIBarButtonItem(image: UIImage(named: "edit"), style: UIBarButtonItemStyle.Plain, target: self, action: "")
editButton.tintColor = UIColor.whiteColor()
var settingsButton : UIBarButtonItem = UIBarButtonItem(image: UIImage(named: "settings"), style: UIBarButtonItemStyle.Plain, target: self, action : "")
settingsButton.tintColor = UIColor.whiteColor()
self.navigationItem.leftBarButtonItem = settingsButton
self.navigationItem.rightBarButtonItem = editButton
self.setUpList()
}
func setUpList()
{
var list1 = List(name:"Apple")
var list2 = List(name:"Banana")
var list3 = List(name:"Orange")
var list4 = List(name:"Pineapple")
var list5 = List(name:"Tomato")
arrayOfList.append(list1)
arrayOfList.append(list2)
arrayOfList.append(list3)
arrayOfList.append(list4)
arrayOfList.append(list5)
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrayOfList.count
}
func tableView(tableView: UITableView,
cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell: CustomCell = tableView.dequeueReusableCellWithIdentifier("Cell") as CustomCell
let list = arrayOfList[indexPath.row]
cell.setCell(list.name)
return cell
}
func tableView(tableView: UITableView!, canEditRowAtIndexPath indexPath: NSIndexPath!) -> Bool {
return true
}
func tableView(tableView: UITableView!, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath!) {
if (editingStyle == UITableViewCellEditingStyle.Delete) {
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
