Question

我想在UITableViewCell中显示信息。我希望能够在单元格上向左滑动，而不是显示deleteCellButton我想看到一段内容。如何覆盖此方法才能做到这一点。

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{

}

您的帮助将不胜感激

Answer 1

您可以使用以下委托方法

-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath {
    return @"Some Content";
}

//正常委托方法

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Determine if it's in editing mode
    if (self.tableView.editing)
    {
        return UITableViewCellEditingStyleDelete;
    }

    return UITableViewCellEditingStyleNone;
}

希望它可以帮助你......！

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

    if (editingStyle == UITableViewCellEditingStyleDelete) 
    {

       //add code here for when you hit delete
       NSLog(@"selected row is : %d",indexPath.row);

           NSString *frndName = [[sections valueForKey:[[[sections allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)] objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];

            NSString *remove = [NSString stringWithFormat:@"Are you sure want to remove '%@' from your friends?",frndName];

            UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"" message:remove delegate:self cancelButtonTitle:@"Remove" otherButtonTitles:@"Cancel", nil];
            av.title = frndName;
            [av show];


     }

}


- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
   NSLog(@"editingStyleForRowAtIndexPath");

    return UITableViewCellEditingStyleDelete;
}


-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath
{

   return @"Remove";
}

如果您想要显示更多操作，可以实施tableView:editActionsForRowAtIndexPath: UITableViewDelegate方法。看一下UITableViewRowAction课程，看看有什么可能： here
