iPhone应用程序访问.net WCF服务，并得到结果在标签

是一个.Net程序员和新手到iPhone应用程序和对象C.iPhone应用程序访问.net WCF服务，并得到结果在标签

我的要求如下。

我需要一个iPhone应用程序，它使用.net WCF服务中的方法，并将结果显示在iPhone中的标签或文本框中。

我有用于乘以2个数字的wcf。当我做NSLog时，它在那里得到结果。但我只需要值即我给5 * 10，我需要50在我的标签。相反，它给予整个东西..

请在这里找到我的代码。

的.h文件

#import <UIKit/UIKit.h> 

@interface iServiceViewController : UIViewController { 
     UILabel *label; 
     NSMutableData *webData; 
} 
@property(nonatomic,retain) IBOutlet UILabel *label; 
@end

M档

#import "iServiceViewController.h" 

@implementation iServiceViewController 
@synthesize label; 



// Implement viewDidLoad to do additional setup after loading the 
view, typically from a nib. 
- (void)viewDidLoad { 
    [super viewDidLoad]; 
     NSString *soapMessage = [NSString stringWithFormat: 
                 @"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"

     NSURL *url = [NSURL

    NSMutableURLRequest *theRequest = [NSMutableURLRequest

    NSString *msgLength = [NSString stringWithFormat:@"%d",

    NSURLConnection *theConnection = [[NSURLConnection alloc] 
initWithRequest:theRequest delegate:self]; 

    if(theConnection) { 
     webData = [[NSMutableData data] retain]; 
    } 
    else { 
     NSLog(@"theConnection is NULL"); 
     }

     [webData setLength:0];

     [connection release]; 

     NSLog(@"Data has been loaded"); 

     //NSString *responseString = [[NSString alloc] initWithData:webData

     //NSInteger *responseInt = [[NSInteger alloc] initWithData:webData

     NSString *responseString = [[NSString alloc] initWithData:webData 
encoding:NSUTF8StringEncoding]; 
     [webData release]; 

     //label.text = responseString; 
     NSLog(responseString); 

     [responseString release]; 

} 

- (void)dealloc { 
    [super dealloc]; 
} 

@end

我NSLog的输出

[Session started at 2011-04-21 12:04:48 +0300.] 
2011-04-21 12:04:49.579 iService[1978:207] Data has been loaded 
2011-04-21 12:04:49.580 iService[1978:207] <s:Envelope 
xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><GetProductResponse 
xmlns="http://tempuri.org/"><GetProductResult>1000</GetProductResult></GetProductResponse></s:Body></s:Envelope>

我试图用10乘以100，我得到结果也。但如何我可以在标签或任何出口..

感谢事先打印只需1000 ..
