call wcf service from xcode4.3 - ios5

Question

I am a .Net programmer and a beginner in Xcode. I want to display the result from a WCF service on the iPad in UITableViewController. I have successfully created stubs for the service by using wsdl2objc. The SOAP message created is as follows:
2012-07-25 14:02:37.169 TestWCF[5280:fb03] OutputHeaders:
{
"Content-Length" = 572;
"Content-Type" = "text/xml; charset=utf-8";
Host = "XXX.XXX.XXX";
SOAPAction = "http://tempuri.org/IDocSync/getAllCategories";
"User-Agent" = wsdl2objc;
}
2012-07-25 14:02:37.172 TestWCF[5280:fb03] OutputBody:

</s:Body>
</s:Envelope>
The code in Appdelegate.m is:
- (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;
}
When I run this,nothing is displayed in the Simulator...it shows a blank screen. There is something very obvious that I am missing. How can I get it working?

Answer 1

I wrote a few tutorials using Wsdl2Objc a while back; maybe they can help.
