Xcode 没有调用 asp.net webservice

Question

我有 Oracle 数据库并使用 Web 服务，我想在其中插入一些记录 所以我在asp.net中创建了web服务，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;

    }

这个函数为我完成了所有数据插入技巧我在本地机器上使用ip地址测试了这个服务 http:72.44.151.178/PickPillService.asmx 然后， 我看到一个关于如何将 ASP.NET Web 服务附加到 iPhone 应用程序的示例 http://www.devx.com/wireless/Article/43209/ 0/页/4 然后我在 xcode 中创建了类似的代码，其中有 2 个文件

1. ConsumePillServiceViewController.m
2. ConsumePillServiceViewController.h 文件

现在， 使用 xcode 的设计器，我创建了 5 个文本框（Me_id、Mem_device_id、Test_datetime、Creation_id、PillBayNo），其中所有参数均根据我们的服务需求进行硬编码 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;

我做了网站中所示的所有操作，当我构建应用程序时，它成功构建了 但在调试窗口中我看到

如果一切正常它应该返回 true 这个 ORA-00936 错误是什么意思，

因为它与 webservice

无关请帮我解决这个问题
