使用Web服务iOS删除数据

Question

如何使用web服务删除数据？

我将UILabel作为CustomTableviewCell.h中的uiOid。现在我在ViewController.m中使用uiOid作为cell.uiOid.text=[orid objectAtIndex:indexPath.row];。这里orid是用于从Web服务检索记录的NSMutablearray。我正确检索了数据，但我的问题是如何删除？我正在使用Web服务删除数据。

我在中插入了删除Web服务

//更新//

- (void)tableView:(UITableView *)aTableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete)
  {      
    [desc removeObjectAtIndex:indexPath.row];
    [item removeObjectAtIndex:indexPath.row];
    [cpack removeObjectAtIndex:indexPath.row];
    [uprice removeObjectAtIndex:indexPath.row];
    [cprice removeObjectAtIndex:indexPath.row];
    [quantity removeObjectAtIndex:indexPath.row];
    [total removeObjectAtIndex:indexPath.row];
    [orid removeObjectAtIndex:indexPath.row];

    NSLog(@"%@",[uid objectForKey:@"OID"]);
    NSLog(@"%@",orid);

    NSString *soapmessage = [NSString stringWithFormat:
                             @"<?xml version="1.0" encoding="utf-8"?>n"
                             "<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">n"
                             "<soap:Body>n"
                             "<DeleteValue xmlns="http://tempuri.org/">n"
                             "<oid>%@</oid>"
                             "</DeleteValue>n"
                             "</soap:Body>n"
                             "</soap:Envelope>n",orid
                             ];
    NSLog(@"%@",soapmessage);
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",appdev.hostname]];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapmessage length]];
    [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [theRequest addValue: @"http://tempuri.org/DeleteVaue" forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody: [soapmessage dataUsingEncoding:NSUTF8StringEncoding]];
}
[mytableview reloadData];
}

方法。当我放入静态编号"89291"时，数据成功删除（对多次操作无效）。但我想在webservice中传递orid (NSMutableArray)，而不是静态数字。我该怎么解决这个问题？谢谢你的帮助。

Answer 1

从DataAry 中删除

[orid removeObjectAtIndex:indexPath.row];
[yourTableView reloadData];  

并创建一个webService来从ServerDataBase中删除此记录。

Answer 2

在您的删除服务方法中传递此信息：

[orid objectAtIndex:indexPath.row];

它在每次从表中删除一行时执行。之后：

[orid removeObjectAtIndex:indexPath.row];
[aTableView reloadData];
