Swipe to expose “More” "Flag" "Archive" buttons (like in Mail app on iOS 8) [duplicate]

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.

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) -> [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];
}

I have created a new library to implement swippable buttons which supports a variety of transitions and expandable buttons like iOS 8 mail app.

https://github.com/MortimerGoro/MGSwipeTableCell

This library is compatible with all the different ways to create a UITableViewCell and its tested on iOS 5, iOS 6, iOS 7 and iOS 8.

Here a sample of some transitions:

Border transition:

Clip transition

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...
    }
