当用户在表格视图中滑动单元格时,如何创建一个“更多”按钮(就像ios 7中的邮件应用程序)

我一直在这里和Cocoa Touch论坛上寻找这些信息,但我似乎找不到答案,我希望比我更聪明的人能给我一个解决方案。

我希望当用户滑动一个表格视图单元格时,显示多个编辑按钮(默认是删除按钮)。 在iOS 7的邮件应用程序中,你可以滑动删除,但会出现一个“更多”按钮。

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

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
}

这是一个(相当可笑的)私有API。

下面两个方法是私有的,并且被发送给UITableView的委托:

-(NSString *)tableView:(UITableView *)tableView titleForSwipeAccessoryButtonForRowAtIndexPath:(NSIndexPath *)indexPath;
-(void)tableView:(UITableView *)tableView swipeAccessoryButtonPushedForRowAtIndexPath:(NSIndexPath *)indexPath;

它们不言自明。

用于快速编程

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
  if editingStyle == UITableViewCellEditingStyle.Delete {
    deleteModelAt(indexPath.row)
    self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
  }
  else if editingStyle == UITableViewCellEditingStyle.Insert {
    println("insert editing action")
  }
}

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
  var archiveAction = UITableViewRowAction(style: .Default, title: "Archive",handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) in
        // maybe show an action sheet with more options
        self.tableView.setEditing(false, animated: false)
      }
  )
  archiveAction.backgroundColor = UIColor.lightGrayColor()

  var deleteAction = UITableViewRowAction(style: .Normal, title: "Delete",
      handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) in
        self.deleteModelAt(indexPath.row)
        self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic);
      }
  );
  deleteAction.backgroundColor = UIColor.redColor()

  return [deleteAction, archiveAction]
}

func deleteModelAt(index: Int) {
  //... delete logic for model
}

以下内容可能会帮到你:

-(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...
}

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...
    }
