Ios5 从xcode4.3调用wcf服务

我是一名.Net程序员，也是Xcode的初学者。我想在UITableViewController中显示iPad上WCF服务的结果。我已经使用wsdl2objc成功地为服务创建了存根。创建的SOAP消息如下所示：

  Host = "XXX.XXX.XXX";
  SOAPAction = "http://tempuri.org/IDocSync/getAllCategories";
  "User-Agent" = wsdl2objc;
}

当我运行此程序时，模拟器中没有显示任何内容…它显示一个空白屏幕。很明显，我遗漏了一些东西。如何让它工作？

前一段时间，我用Wsdl2Objc编写了一些教程；也许他们能帮上忙

：-我按照你的例子做了，效果很好。但我想要达到的是有点不同。教程示例返回标记中的单个值。我正在处理的示例返回一个对象数组（复杂类型）。我想在表格中显示“某些值”和“值”。如何实现这一点？@from.nett您需要检查Wsdl2obj创建的代码。特别是，它会使一个类对应于（它可能会被命名为类似于_Response的东西，在该类中，您可能会看到对应于的对象数组的规定）

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
   BasicHttpBinding_IDocSyncBinding *myBinding = [iPadDocSyncServiceSvc    BasicHttpBinding_IDocSyncBinding];
myBinding.logXMLInOut = YES;

//iPadDocSyncServiceSvc_getAllCategories *allCate =     [[iPadDocSyncServiceSvc_getAllCategories new]autorelease];
iPadDocSyncServiceSvc_getAllCategories *allCate = [[iPadDocSyncServiceSvc_getAllCategories     alloc]init];

BasicHttpBinding_IDocSyncBindingResponse *response = [myBinding getAllCategoriesUsingParameters:allCate];

for(id bodyPart in response.bodyParts)
{
    //if([bodyPart isKindOfClass:[BasicHttpBinding_IDocSyncBindingResponse class]])
    //{
    //tns1_ArrayOfCategory *cateClass = (tns1_ArrayOfCategory *) bodyPart;
    //[self.tableView reloadData];

    //categories  = (NSMutableArray *) cateClass;
    //tns1_ArrayOfCategory *cateClass = [bodyPart getAllCategoriesResult];

    self.categories = (NSMutableArray *) [bodyPart getAllCategoriesResult];
    //}
}


return YES;
}
