我认为您不能在这个默认的删除按钮中插入任何内容，您需要构建自己的按钮。Ray Wenderlich的网站上有一个很好的指南，可以帮助您实现这一点：

我想这个答案也许是你想要的

引述：

- (void)willTransitionToState:(UITableViewCellStateMask)state{
[super willTransitionToState:state];
if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask) {
    for (UIView *subview in self.subviews) {
        if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {
            UIImageView *deleteBtn = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 64, 33)];
            [deleteBtn setImage:[UIImage imageNamed:@"delete.png"]];
            [[subview.subviews objectAtIndex:0] addSubview:deleteBtn];
            [deleteBtn release];
        }
    }
}
}

迅速地

class TableViewRowAction: UITableViewRowAction 
{
    var image: UIImage?

    func _setButton(button: UIButton)  {

        if let image = image, let titleLabel = button.titleLabel {

             let labelString = NSString(string: titleLabel.text!)
             let titleSize = labelString.sizeWithAttributes([NSFontAttributeName: titleLabel.font])
             button.tintColor = UIColor.whiteColor()
             button.setImage(image.imageWithRenderingMode(.AlwaysTemplate), forState: .Normal)
             button.imageEdgeInsets.right = -titleSize.width
        }
    }
}


func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {


    let moreRowAction = TableViewRowAction(style: UITableViewRowActionStyle.Default, title: "        ") { action, indexPath in
        // Action Block of more button.
    }

    moreRowAction.image = UIImage(named: "edit_white")
    moreRowAction.backgroundColor = UIColor(red: 252/255, green: 65/255, blue: 75/255, alpha: 1.0)



    let deleteRowAction = TableViewRowAction(style: UITableViewRowActionStyle.Default, title: "        ") { action, indexPath in
          // Action Block of delete button.

    }

    deleteRowAction.backgroundColor = UIColor(red: 252/255, green: 65/255, blue: 75/255, alpha: 1.0)
    deleteRowAction.image = UIImage(named: "delete_white")

    return [deleteRowAction, moreRowAction]

}

您是否在项目中使用CoCoapod。查看“SWTableViewCell”。它可能会帮助您实现此功能

class TableViewRowAction: UITableViewRowAction 
{
    var image: UIImage?

    func _setButton(button: UIButton)  {

        if let image = image, let titleLabel = button.titleLabel {

             let labelString = NSString(string: titleLabel.text!)
             let titleSize = labelString.sizeWithAttributes([NSFontAttributeName: titleLabel.font])
             button.tintColor = UIColor.whiteColor()
             button.setImage(image.imageWithRenderingMode(.AlwaysTemplate), forState: .Normal)
             button.imageEdgeInsets.right = -titleSize.width
        }
    }
}


func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {


    let moreRowAction = TableViewRowAction(style: UITableViewRowActionStyle.Default, title: "        ") { action, indexPath in
        // Action Block of more button.
    }

    moreRowAction.image = UIImage(named: "edit_white")
    moreRowAction.backgroundColor = UIColor(red: 252/255, green: 65/255, blue: 75/255, alpha: 1.0)



    let deleteRowAction = TableViewRowAction(style: UITableViewRowActionStyle.Default, title: "        ") { action, indexPath in
          // Action Block of delete button.

    }

    deleteRowAction.backgroundColor = UIColor(red: 252/255, green: 65/255, blue: 75/255, alpha: 1.0)
    deleteRowAction.image = UIImage(named: "delete_white")

    return [deleteRowAction, moreRowAction]
