iOS 9에서 스 와이프 가능한 표보기 셀

내 테이블 목록에 iOS 8 (iOS 7에서 처음 도입 됨)과 같이 스 와이프 할 수있는 메뉴가 있어야합니다.

방법에 대한 명확한 Ray Wenderlich 가이드를 찾았 지만 1 년 4 개월 전에 작성되었으며 코드는 Objective-C에 있습니다.

iOS 8 또는 곧 출시 될 iOS 9가 마침내이 기능을 Apple의 SDK에 포함 시켰습니까? 몇 년 전에 "스 와이프하여 삭제 기능 표시"를 내장 한 것으로 알고 있습니다. Apple의 새로운 iOS가 깔끔하게 포장 된 패키지로 나에게 전달한다면 iOS 8 메일 기능을 모방하기 위해 함께 패치 된 코드를 구현하는 데 시간을 낭비하고 싶지 않습니다.

이 시도. (Swift 3.0으로 업데이트 됨) ( 개발자 문서 )

override func tableView(_ tableView: UITableView, editActionsForRowAt: IndexPath) -> [UITableViewRowAction]? {
    let more = UITableViewRowAction(style: .normal, title: "More") { action, index in
        print("more button tapped")
    }
    more.backgroundColor = .lightGray

    let favorite = UITableViewRowAction(style: .normal, title: "Favorite") { action, index in
        print("favorite button tapped")
    }
    favorite.backgroundColor = .orange

    let share = UITableViewRowAction(style: .normal, title: "Share") { action, index in
        print("share button tapped")
    }
    share.backgroundColor = .blue

    return [share, favorite, more]
}

또한 이것을 구현하십시오 : (조건부로 만들 수 있지만 여기에서는 모든 것이 편집 가능합니다)

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

(이전 버전)

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
        let more = UITableViewRowAction(style: .Normal, title: "More") { action, index in
            print("more button tapped")
        }
        more.backgroundColor = UIColor.lightGrayColor()

        let favorite = UITableViewRowAction(style: .Normal, title: "Favorite") { action, index in
            print("favorite button tapped")
        }
        favorite.backgroundColor = UIColor.orangeColor()

        let share = UITableViewRowAction(style: .Normal, title: "Share") { action, index in
            print("share button tapped")
        }
        share.backgroundColor = UIColor.blueColor()

        return [share, favorite, more]
    }

    func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
        // the cells you would like the actions to appear needs to be editable
        return true
    }

이 코드는 swift4에서 저에게 효과적입니다.

위 화면의 답은 다음과 같습니다.

 func tableView(_ tableView: UITableView,
                   trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
    {
        // Write action code for the trash
        let TrashAction = UIContextualAction(style: .normal, title:  "Trash", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
            print("Update action ...")
            success(true)
        })
        TrashAction.backgroundColor = .red

        // Write action code for the Flag
        let FlagAction = UIContextualAction(style: .normal, title:  "Flag", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
            print("Update action ...")
            success(true)
        })
        FlagAction.backgroundColor = .orange

        // Write action code for the More
        let MoreAction = UIContextualAction(style: .normal, title:  "More", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
            print("Update action ...")
            success(true)
        })
        MoreAction.backgroundColor = .gray


        return UISwipeActionsConfiguration(actions: [TrashAction,FlagAction,MoreAction])
    }

위 화면의 답변 :-

 func tableView(_ tableView: UITableView,
                   leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
    {

        let closeAction = UIContextualAction(style: .normal, title:  "Mark as Read", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
            print("CloseAction ...")
            success(true)
        })
        closeAction.backgroundColor = .blue
        return UISwipeActionsConfiguration(actions: [closeAction])

    }

다음과 같이 tableview Delegate 메소드를 작성하십시오.

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return arrPerson.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        let personName = arrPerson[indexPath.row]
        cell.textLabel?.text = personName.personName
        return cell

    }

그리고 viewDidLoad에서

override func viewDidLoad() {
    super.viewDidLoad()

    tblView.delegate = self
    tblView.dataSource = self

    let person1 = personData(personName: "Jonny", personAge: 30)
    let person2 = personData(personName: "Chandan", personAge: 20)
    let person3 = personData(personName: "Gopal", personAge: 28)

   arrPerson.append(person1)
   arrPerson.append(person2)
   arrPerson.append(person3)

}

UITableView 대리자 메서드를 사용하여 이러한 작업을 요청할 수 있습니다. 이 메소드를 다음과 같이 구현하십시오.

- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {
     UITableViewRowAction *modifyAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"Modify" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
         // Respond to the action.
     }];
     modifyAction.backgroundColor = [UIColor blueColor];
     return @[modifyAction];
}

물론 여러 작업을 반환하고 텍스트 및 배경 색상을 사용자 지정할 수 있습니다.

행을 편집 가능하게하려면이 메소드를 구현해야합니다.

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
}

이 라이브러리 MGSwipeTableCell을 찾았습니다. swift를 사용하여 테이블보기에서 슬라이드 셀을 구현하기 위해 많은 것을 검색 한 후 구현을 수행하는 코드 한 줄과 이것이 매우 유용하다는 것을 발견했습니다.

     func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
  {
    let reuseIdentifier = "programmaticCell"
    var cell = self.table.dequeueReusableCellWithIdentifier(reuseIdentifier) as! MGSwipeTableCell!
    if cell == nil
    {
      cell = MGSwipeTableCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: reuseIdentifier)
    }

    cell.textLabel!.text = "Title"
    cell.detailTextLabel!.text = "Detail text"
    cell.delegate = self //optional

    //configure left buttons
    cell.leftButtons = [MGSwipeButton(title: "", icon: UIImage(named:"check.png"), backgroundColor: UIColor.greenColor())
      ,MGSwipeButton(title: "", icon: UIImage(named:"fav.png"), backgroundColor: UIColor.blueColor())]
    cell.leftSwipeSettings.transition = MGSwipeTransition.Rotate3D

    //configure right buttons
    cell.rightButtons = [MGSwipeButton(title: "Delete", backgroundColor: UIColor.redColor())
      ,MGSwipeButton(title: "More",backgroundColor: UIColor.lightGrayColor())]
    cell.rightSwipeSettings.transition = MGSwipeTransition.Rotate3D

    return cell
  }

그것이 당신의 포드 파일을 구현하고 업데이트해야 할 유일한 기능입니다.

Swift 3 완전한 솔루션 :

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    @IBOutlet weak var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        tableView.tableFooterView = UIView(frame: CGRect.zero) //Hiding blank cells.
        tableView.separatorInset = UIEdgeInsets.zero
        tableView.dataSource = self
        tableView.delegate = self
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

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

        return 4
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "tableCell", for: indexPath)

        return cell
    }

    //Enable cell editing methods.
    func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {

        return true
    }

    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

    }

    func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

        let more = UITableViewRowAction(style: .normal, title: "More") { action, index in
            //self.isEditing = false
            print("more button tapped")
        }
        more.backgroundColor = UIColor.lightGray

        let favorite = UITableViewRowAction(style: .normal, title: "Favorite") { action, index in
            //self.isEditing = false
            print("favorite button tapped")
        }
        favorite.backgroundColor = UIColor.orange

        let share = UITableViewRowAction(style: .normal, title: "Share") { action, index in
            //self.isEditing = false
            print("share button tapped")
        }
        share.backgroundColor = UIColor.blue

        return [share, favorite, more]
    }

}

AFAIK에는 즉시 사용할 수있는 내장형 솔루션이 없으며, iOS9에 있었더라도 가까운 미래에 앱에서 iOS9 만 지원할 수 없기 때문에 사용할 수 없을 것입니다.

대신이 라이브러리를 살펴 보는 것이 좋습니다.

매우 쉽게 구성 할 수 있고, 매우 세련되었으며, 제가 작업 한 모든 신속한 프로젝트에서 잘 작동했습니다.

도움이 되었기를 바랍니다.

생각보다 쉽습니다. 다음은 구현 된 UITableView 및 UITableViewCell 스 와이프 기능이있는 Swift 클래스의 예입니다.

import UIKit

class ViewController: UIViewController {

    // MARK: Properties

    let strings = ["firstString", "secondString", "thirdString"]

    // MARK: Outlets

    @IBOutlet weak var tableView: UITableView!

    // MARK: Lifecycle

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.delegate = self
        tableView.dataSource = self
    }
}

extension ViewController: UITableViewDataSource, UITableViewDelegate {

    // MARK: UITableViewDataSource

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return objects.count
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cellIdentifier", for: indexPath)
        let currentString = strings[indexPath.row]
        cell.textLabel?.text = currentString
        return cell
    }

    // MARK: UITableViewDelegate

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
    }

    func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let leftAction = UIContextualAction(style: .normal, title:  "Red", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
            print("leftAction tapped")
            success(true)
        })

        leftAction.image = UIImage(named: "")
        leftAction.backgroundColor = UIColor.red

        return UISwipeActionsConfiguration(actions: [leftAction])
    }

    func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        let rightAction = UIContextualAction(style: .normal, title:  "Green", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
            print("rightAction tapped")
            success(true)
        })

        rightAction.image = UIImage(named: "")
        rightAction.backgroundColor = UIColor.green

        return UISwipeActionsConfiguration(actions: [rightAction])
    }

}
