Swift 4和iOs 11+

@available(iOS 11.0, *)
override func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {

    let delete = UIContextualAction(style: .destructive, title: "Delete") { _, _, handler in

        handler(true)
        // handle deletion here
    }

    let more = UIContextualAction(style: .normal, title: "More") { _, _, handler in

        handler(true)
        // handle more here
    }

    return UISwipeActionsConfiguration(actions: [delete, more])
}

有一个很棒的库叫做SwipeCellKit，它应该得到更多的认可。在我看来，它比MGSwipeTableCell更酷。后者不能完全复制邮件应用程序单元格的行为，而SwipeCellKit可以。看一看

这里有一种有点脆弱的方法，它不涉及私有api或构造自己的系统。你在对冲赌注，苹果不会打破这一点，希望他们会发布一个API，你可以用它来替换这几行代码。

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].

这还要求您实现标准表视图编辑委托回调。

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:&kObserveContext];

        _editButton = [UIButton new];
        _editButton.backgroundColor = [UIColor lightGrayColor];
        [_editButton setTitle:@"Edit" forState:UIControlStateNormal];
        [_editButton addTarget:self
                        action:@selector(_editTap)

    return self;

        return;
    }

        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 && ![tv isKindOfClass:[UITableView class]]) {
        tv = (id)tv.superview;
    }
    id<UITableViewDelegate> 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];

约翰尼的答案是正确的。我只是在objective-c中添加了下面的代码，以便初学者(以及那些拒绝学习Swift语法的人:)

确保你声明了uitableviewdelegate并拥有以下方法:

 -(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...
    }

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let delete = UIContextualAction(style: .destructive, title: "Delete") { (action, sourceView, completionHandler) in
        print("index path of delete: \(indexPath)")
        completionHandler(true)
    }
    let rename = UIContextualAction(style: .normal, title: "Edit") { (action, sourceView, completionHandler) in
        print("index path of edit: \(indexPath)")
        completionHandler(true)
    }
    let swipeActionConfig = UISwipeActionsConfiguration(actions: [rename, delete])
    swipeActionConfig.performsFirstActionWithFullSwipe = false
    return swipeActionConfig
}

在iOS 11中，这在UITableViewDelegate中是公开的。下面是一些示例代码:

斯威夫特

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

    let action = UIContextualAction(style: .normal, title: nil) { (_, _, _) in
        print("Swipe action tapped")
    }

    action.image = UIImage(systemName: "plus.slash.minus")
    action.backgroundColor = .green

    return UISwipeActionsConfiguration(actions: [action])
}

Objective - C

- (UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath {
    UIContextualAction *delete = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleDestructive
                                                                         title:@"DELETE"
                                                                       handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
                                                                           NSLog(@"index path of delete: %@", indexPath);
                                                                           completionHandler(YES);
                                                                       }];

    UIContextualAction *rename = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal
                                                                         title:@"RENAME"
                                                                       handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
                                                                           NSLog(@"index path of rename: %@", indexPath);
                                                                           completionHandler(YES);
                                                                       }];

    UISwipeActionsConfiguration *swipeActionConfig = [UISwipeActionsConfiguration configurationWithActions:@[rename, delete]];
    swipeActionConfig.performsFirstActionWithFullSwipe = NO;

    return swipeActionConfig;
}

也可用:

- (UISwipeActionsConfiguration *)tableView:(UITableView *)tableView leadingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath;
