ios - 删除时该行不会在 UITableView 中消失

Question

我正在使用数据库中的文件名填充我的 iOS TableView 。一切都按预期显示在 tableView 中。当我删除它时出现问题，它删除了数据库中的条目，但该条目不会在 UITableView 中消失。这是我的代码:

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

        DBHandler *handler;
        [handler ResumeID:[mydataList objectAtIndex:indexPath.row]]; //mydataList contains the array that contains name of all the entries in the DB and is displaying them on the tableview.
        [mydataList removeObjectAtIndex:indexPath.row];
         NSLog(@"%ld",indexPath.row);



        // Animate the deletion from the table.
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

您实际上是将之前删除的值传递给 DBHandler。检查代码，

if (editingStyle == UITableViewCellEditingStyleDelete)
{
    DBHandler *handler ;
    [handler ResumeID:[mydataList objectAtIndex:indexPath.row]]; // Pass the object from the dataSource before deleting the object from the dataSource.

     [mydataList removeObjectAtIndex:indexPath.row]; // Remove object after passing it to the DBHandler
    NSLog(@"%ld",indexPath.row);
    // Animate the deletion from the table.
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}

试试这个。
