Question

我有oracle数据库并使用webservice我想在其中插入一些记录所以我在asp.net中创建了webservice，如下所示

 public bool PickPill(string Me_id, string Mem_device_id, string Test_datetime, string Creation_id, string PillBayNo)
    {
        string Hed_seq_id = Hed_seq_Id();
        bool ResultHED = InsHealthEData(Hed_seq_id, Mem_device_id, Me_id, Test_datetime, Creation_id);
        bool ResultHET = InsHealthETest(Hed_seq_id, PillBayNo, Test_datetime, Creation_id);

        if (ResultHED == ResultHET == true)
            return true;
        else
            return false;

    }

这个功能为我做了所有数据插入技巧我用ip地址在本地机器上测试了这个服务 HTTP：72.44.151.178/PickPillService.asmx 然后，我看到了如何将asp.net Web服务附加到iphone应用程序的示例 http://www.devx.com/wireless/Article/43209/0/page/4 然后我在xcode中创建了simillar代码，其中包含2个文件

ConsumePillServiceViewController.m
ConsumePillServiceViewController.h文件

现在，使用xcode的Designer我创建了5个文本框（Me_id，Mem_device_id，Test_datetime，Creation_id，PillBayNo），所有参数都是hardcode作为我们的服务需求然后修改我的ConsumePillServiceViewController.h文件，如下所示

@interface ConsumePillServiceViewController : UIViewController {
 //---outlets---
  IBOutlet UITextField *Me_id;
  IBOutlet UITextField *Mem_device_id;
  IBOutlet UITextField *Test_datetime;
  IBOutlet UITextField *Creation_id;
  IBOutlet UITextField *PillBayNo;
 //---web service access---
    NSMutableData *webData;
    NSMutableString *soapResults;
    NSURLConnection *conn;

}
@property (nonatomic, retain) UITextField *Me_id;
@property (nonatomic, retain) UITextField *Mem_device_id;
@property (nonatomic, retain) UITextField *Test_datetime;
@property (nonatomic, retain) UITextField *Creation_id;
@property (nonatomic, retain) UITextField *PillBayNo;
- (IBAction)buttonClicked:(id)sender;
@end

and 
ConsumePillServiceViewController.m as follows

#import "ConsumePillServiceViewController.h"

@implementation ConsumePillServiceViewController
@synthesize Me_id;
@synthesize Mem_device_id;
@synthesize Test_datetime;
@synthesize Creation_id;

我做了网站上显示的所有内容，当我构建应用程序时，它已成功构建但是在调试窗口中我看到了

如果一切正常，它应该归还我什么是ORA-00936错误

因为它没有与webservice相关

请帮我解决这个问题

Xcode没有调用asp.net webservice
