Swipe to Delete and the More button like in Mail app on iOS 7

Question

How to create a  more  button when user swipe a cell in table view  like mail app in ios 7   I have been looking for this information both here and in the Cocoa Touch forum  but I cannot seem to find the answer and I am hoping someone smarter than myself can give me a solution   I would like that when the user swipes a table view cell  to display more than one editing button  he default is the delete button   In the Mail app for iOS 7 you can swipe to delete  but there is a  MORE  button that shows up

I hope you cant wait till apple gives you what ever you need right? So here is my option.

Create a custom cell. Have two uiviews in it

1. upper
2. lower

In lower view, add what ever buttons you need. Deal its actions just like any other IBActions. you can decide the animation time, style and anything.

now add a uiswipegesture to the upper view and reveal your lower view on swipe gesture. I have done this before and its the simplest option as far as I am concerned.

Hope that help.

Actual Swift 3 Answer  This is the ONLY function you need  You do not need CanEdit or CommitEditingStyle functions for custom actions   func tableView   tableView  UITableView  editActionsForRowAt indexPath  IndexPath  - gt   UITableViewRowAction         let action1   UITableViewRowAction style   default  title   Action1   handler             action  indexPath  in         print  Action1              action1 backgroundColor   UIColor lightGray     let action2   UITableViewRowAction style   default  title   Action2   handler             action  indexPath  in         print  Action2              return  action1  action2

Here is one simple solution  It is capable to display and hide custom UIView inside UITableViewCell   Displaying logic is contained inside class extended from UITableViewCell  BaseTableViewCell   BaseTableViewCell h    import  lt UIKit UIKit h gt    interface BaseTableViewCell   UITableViewCell   property nonatomic strong UIView  customView   - void showCustomView   - void hideCustomView    end   BaseTableViewCell M   import  BaseTableViewCell h    interface BaseTableViewCell         BOOL  isCustomViewVisible      end   implementation BaseTableViewCell  -  void awakeFromNib          Initialization code    - void prepareForReuse       self customView   nil       isCustomViewVisible   NO     -  void setSelected  BOOL selected animated  BOOL animated        super setSelected selected animated animated           Configure the view for the selected state    - void showCustomView       if nil    self customView                if   isCustomViewVisible                         isCustomViewVisible   YES               if  self customView superview                                CGRect frame   self customView frame                  frame origin x   self contentView frame size width                  self customView frame   frame                   self customView willMoveToSuperview self contentView                    self contentView addSubview self customView                    self customView didMoveToSuperview                                weak BaseTableViewCell  blockSelf   self               UIView animateWithDuration  5 animations                       for UIView  view in blockSelf contentView subviews                                        CGRect frame   view frame                      frame origin x   frame origin x - blockSelf customView frame size width                      view frame   frame                                                       - void hideCustomView       if nil    self customView                if  isCustomViewVisible                          weak BaseTableViewCell  blockSelf   self               isCustomViewVisible   NO               UIView animateWithDuration  5 animations                      for UIView  view in blockSelf contentView subviews                                        CGRect frame   view frame                      frame origin x   frame origin x   blockSelf customView frame size width                      view frame   frame                                                        end   To get this functionality  simple extend your table view cell from BaseTableViewCell   Next  Inside UIViewController  which implement UITableViewDelegate  create two gesture recognizers to handle left and right swipes   -  void viewDidLoad        super viewDidLoad          Do any additional setup after loading the view  typically from a nib        self tableView registerNib  UINib nibWithNibName CUSTOM CELL NIB NAME bundle nil  forCellReuseIdentifier CUSTOM CELL ID        UISwipeGestureRecognizer  leftSwipeRecognizer     UISwipeGestureRecognizer alloc  initWithTarget self action  selector handleLeftSwipe         leftSwipeRecognizer direction   UISwipeGestureRecognizerDirectionLeft       self tableView addGestureRecognizer leftSwipeRecognizer        UISwipeGestureRecognizer  rightSwipeRecognizer     UISwipeGestureRecognizer alloc  initWithTarget self action  selector handleRightSwipe         rightSwipeRecognizer direction   UISwipeGestureRecognizerDirectionRight       self tableView addGestureRecognizer rightSwipeRecognizer       Than add two swipe handlers  -  void handleLeftSwipe  UISwipeGestureRecognizer  recognizer       CGPoint point    recognizer locationInView self tableView       NSIndexPath  index    self tableView indexPathForRowAtPoint point        UITableViewCell  cell    self tableView cellForRowAtIndexPath index        if  cell respondsToSelector  selector showCustomView                   cell performSelector  selector showCustomView             -  void handleRightSwipe  UISwipeGestureRecognizer  recognizer       CGPoint point    recognizer locationInView self tableView       NSIndexPath  index    self tableView indexPathForRowAtPoint point        UITableViewCell  cell    self tableView cellForRowAtIndexPath index        if  cell respondsToSelector  selector hideCustomView                   cell performSelector  selector hideCustomView              Now  inside cellForRowAtIndexPath  of UITableViewDelegate  you can create custom UIView and attach it to the dequeued cell   - UITableViewCell  tableView  UITableView   tableView cellForRowAtIndexPath  NSIndexPath   indexPath       CustomCellTableViewCell  cell    CustomCellTableViewCell   tableView dequeueReusableCellWithIdentifier   CustomCellTableViewCell  forIndexPath indexPath        NSArray  nibViews     NSBundle mainBundle  loadNibNamed   CellCustomView                                                        owner nil                                                     options nil        CellCustomView  customView    CellCustomView    nibViews objectAtIndex  0        cell customView   customView       return cell      Of course  this way of loading of custom UIView is just for this example  Manage it as you want

I was looking to add the same functionality to my app  and after going through so many different tutorials  raywenderlich being the best DIY solution   I found out that Apple has its own UITableViewRowActionclass  which is very handy    You have to change the Tableview s boilerpoint method to this   override func tableView tableView  UITableView  editActionsForRowAtIndexPath indexPath  NSIndexPath  -

This is not possible using the standard SDK  However there are various 3rd party solutions that more or less imitate the behavior in Mail app  Some of them  e g  MCSwipeTableViewCell  DAContextMenuTableViewController  RMSwipeTableViewCell  detect swipes using gesture recognizers  some of them  e g  SWTableViewCell  put a second UISScrollView below the standard UITableViewCellScrollView  private subview of UITableViewCell  and some of them modify the behavior of UITableViewCellScrollView    I like the last approach most since the touch handling feels most natural  Specifically  MSCMoreOptionTableViewCell is good  Your choice may vary depending on your specific needs  whether you need a left-to-right pan  too  whether you need iOS 6 compatibility  etc    Also be aware that most of these approaches come with a burden  they can easily break in a future iOS version if Apple makes changes in the UITableViewCell subview hierarchy

This is  rather ridiculously  a private API   The following two methods are private and sent to the UITableView s delegate   - NSString   tableView  UITableView   tableView titleForSwipeAccessoryButtonForRowAtIndexPath  NSIndexPath   indexPath  - void tableView  UITableView   tableView swipeAccessoryButtonPushedForRowAtIndexPath  NSIndexPath   indexPath    They are pretty self explanatory

How to Implement  It looks like iOS 8 opens up this API  Hints of such functionality are present in Beta 2    To get something working  implement the following two methods on your UITableView s delegate to get the desired effect  see gist for an example    - tableView editActionsForRowAtIndexPath  - tableView commitEditingStyle forRowAtIndexPath      Known Issues  The documentation says tableView commitEditingStyle forRowAtIndexPath is       Not called for edit actions using UITableViewRowAction - the action s handler will be invoked instead     However  the swiping doesn t work without it  Even if the method stub is blank  it still needs it  for now  This is most obviously a bug in beta 2     Sources  https   twitter com marksands status 481642991745265664 https   gist github com marksands 76558707f583dbb8f870  Original Answer  https   stackoverflow com a 24540538 870028    Update   Sample code with this working  In Swift   http   dropbox com s 0fvxosft2mq2v5m DeleteRowExampleSwift zip  The sample code contains this easy-to-follow method in MasterViewController swift  and with just this method you get the behavior shown in the OP screenshot   override func tableView tableView  UITableView  editActionsForRowAtIndexPath indexPath  NSIndexPath  - gt   AnyObject          var moreRowAction   UITableViewRowAction style  UITableViewRowActionStyle Default  title   More   handler  action  indexpath in         println  MORE   ACTION                moreRowAction backgroundColor   UIColor red  0 298  green  0 851  blue  0 3922  alpha  1 0        var deleteRowAction   UITableViewRowAction style  UITableViewRowActionStyle Default  title   Delete   handler  action  indexpath in         println  DELETE   ACTION                 return  deleteRowAction  moreRowAction

You need to subclass UITableViewCell and subclass method willTransitionToState  UITableViewCellStateMask state which is called whenever user swipes the cell  The state flags will let you know if the Delete button is showing  and show hide your More button there    Unfortunately this method gives you neither the width of the Delete button nor the animation time  So you need to observer  amp  hard-code your More button s frame and animation time into your code  I personally think Apple needs to do something about this

Johnny s answer is the right one to upvote  I m just adding this below in objective-c to make it clearer to beginners  and those of us who refuse to learn Swift syntax     Make sure you declare the uitableviewdelegate and have the following methods    - NSArray   tableView  UITableView   tableView editActionsForRowAtIndexPath  NSIndexPath   indexPath    UITableViewRowAction  button    UITableViewRowAction rowActionWithStyle UITableViewRowActionStyleDefault title   Button 1  handler   UITableViewRowAction  action  NSIndexPath  indexPath                NSLog   Action to perform with Button 1                button backgroundColor    UIColor greenColor     arbitrary color     UITableViewRowAction  button2    UITableViewRowAction rowActionWithStyle UITableViewRowActionStyleDefault title   Button 2  handler   UITableViewRowAction  action  NSIndexPath  indexPath                                                                                NSLog   Action to perform with Button2                                                 button2 backgroundColor    UIColor blueColor     arbitrary color      return   button  button2     array with all the buttons you want  1 2 3  etc       -  void tableView  UITableView   tableView commitEditingStyle  UITableViewCellEditingStyle editingStyle forRowAtIndexPath  NSIndexPath   indexPath      you need to implement this method too or nothing will work      -  BOOL tableView  UITableView   tableView canEditRowAtIndexPath  NSIndexPath   indexPath               return YES    tableview must be editable or nothing will work

Here s a somewhat fragile way of doing it that does not involve private APIs or constructing your own system   You re hedging your bets that Apple doesn t break this and that hopefully they will release an API that you can replace these few lines of code with    KVO self contentView superview layer sublayer   Do this in init   This is the UIScrollView s layer   You can t KVO  subviews   When subviews changes  find the delete confirmation view within scrollview subviews   This is done in the observe callback  Double the size of that view and add a UIButton to the left of its only subview   This is also done in the observe callback   The only subview of the delete confirmation view is the delete button   optional  The UIButton event should look up self superview until it finds a UITableView and then call a datasource or delegate method you create  such as tableView commitCustomEditingStyle forRowAtIndexPath    You may find the indexPath of the cell by using  tableView indexPathForCell self     This also requires that you implement the standard table view editing delegate callbacks   static char kObserveContext   0    implementation KZTableViewCell       UIScrollView   contentScrollView      UIView   confirmationView      UIButton   editButton      UIButton   deleteButton     -  id initWithStyle  UITableViewCellStyle style reuseIdentifier  NSString   reuseIdentifier       self    super initWithStyle style reuseIdentifier reuseIdentifier       if  self             contentScrollView    id self contentView superview             contentScrollView layer addObserver self              forKeyPath   sublayers                  options 0                 context  amp kObserveContext             editButton    UIButton new            editButton backgroundColor    UIColor lightGrayColor             editButton setTitle   Edit  forState UIControlStateNormal             editButton addTarget self                         action  selector  editTap                forControlEvents UIControlEventTouchUpInside              return self     - void dealloc         contentScrollView layer removeObserver self forKeyPath   sublayers  context  amp kObserveContext      - void observeValueForKeyPath  NSString   keyPath ofObject  id object change  NSDictionary   change context  void   context       if context     amp kObserveContext             super observeValueForKeyPath keyPath ofObject object change change context context           return            if object     contentScrollView layer            for UIView   view in  contentScrollView subviews                if  NSStringFromClass view class  hasSuffix   ConfirmationView                       confirmationView   view                   deleteButton    view subviews objectAtIndex 0                   CGRect frame    confirmationView frame                  CGRect frame2   frame                  frame origin x -  frame size width                  frame size width    2                   confirmationView frame   frame                   frame2 origin   CGPointZero                   editButton frame   frame2                  frame2 origin x    frame2 size width                   deleteButton frame   frame2                    confirmationView addSubview  editButton                   break                                  return           - void  editTap       UITableView  tv    id self superview      while tv  amp  amp    tv isKindOfClass  UITableView class              tv    id tv superview            id lt UITableViewDelegate gt  delegate   tv delegate      if  delegate respondsToSelector  selector tableView editTappedForRowWithIndexPath               NSIndexPath  ip    tv indexPathForCell self              define this in your own protocol          delegate tableView tv editTappedForRowWithIndexPath ip            end
