WCF call nested in a WCF call - ios

Question

I have a backend made in C#, where I am making WCF calls to from iOS. It works pretty good, but I am stuck in a problem
Code:
#import "ListTableViewController.h"
#import "ListServiceSvc.h"
#import "LoginViewController.h"
#interface ListTableViewController (){
NSMutableArray *productsFromWebServer;
NSMutableDictionary *prodForList;
}
#property (nonatomic, retain) NSMutableArray *shoppingList;
#property (nonatomic, retain) NSMutableArray *productList;
#end
#implementation ListTableViewController
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void) viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
Boolean b = [standardUserDefaults boolForKey:#"HasTokenKey"];
if (!b)
{
[self showLoginViewController];
}
[self loadListsFromRemoteServer];
[self.tableView reloadData];
//self.uname.text = [standardUserDefaults objectForKey:#"username"];
}
- (void) showLoginViewController {
LoginViewController* loginController = (LoginViewController*) [ApplicationDelegate.storyBoard instantiateViewControllerWithIdentifier:#"LoginViewController"];
[self presentViewController:loginController animated:YES completion:nil];
}
- (void)userDidLeave
{
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
[standardUserDefaults setBool:NO forKey:#"HasTokenKey"];
// Show the Login screen.
[self showLoginViewController];
}
- (IBAction)exitAction
{
[self userDidLeave];
}
- (void)viewDidLoad
{
_shoppingList = [NSMutableArray array];
_productList = [NSMutableArray array];
//[self loadListsFromRemoteServer];
[super viewDidLoad];
}
-(void) loadListsFromRemoteServer
{
NSString *uname = [[NSUserDefaults standardUserDefaults] objectForKey:#"username"];
NemListBinding *binding = [[ListServiceSvc NemListBinding]initWithAddress:#"http://balder/dm76_gr5/WCF.ListService.svc/custom?singleWsdl"];
binding.logXMLInOut=YES;
ListServiceSvc_GetShoppingListsWithUname *parms = [[ListServiceSvc_GetShoppingListsWithUname alloc]init];
parms.uname = uname;
[binding GetShoppingListsWithUnameAsyncUsingParameters:parms delegate:self];
}
-(void) loadItemsInList:(NSNumber*)slistId
{
NemListBinding *binding = [[ListServiceSvc NemListBinding]initWithAddress:#"http://balder/dm76_gr5/WCF.ListService.svc/custom?singleWsdl"];
binding.logXMLInOut=YES;
ListServiceSvc_GetProductsWithListId *parms = [[ListServiceSvc_GetProductsWithListId alloc]init];
parms.listId = slistId;
[binding GetProductsWithListIdAsyncUsingParameters:parms delegate:self];
}
- (void) operation:(NemListBindingOperation *)operation completedWithResponse:(NemListBindingResponse *)response
{
NSArray *responseHeaders = response.headers;
NSArray *responseBodyParts = response.bodyParts;
[NSThread sleepForTimeInterval:1.0];
NSMutableArray *shoppingListFromWebserver = [[NSMutableArray alloc] init];
productsFromWebServer = [[NSMutableArray alloc]init];
prodForList = [[NSMutableDictionary alloc]init];
// step 1 fill in the blanks.
for(id header in responseHeaders) {
// here do what you want with the headers, if there's anything of value in them
}
for (id mine in responseBodyParts)
{
if ([mine isKindOfClass:[ListServiceSvc_GetShoppingListsWithUnameResponse class]])
{
for (id slist in [[mine GetShoppingListsWithUnameResult] ShoppingList])
{
[shoppingListFromWebserver addObject:slist];
[self loadItemsInList:[slist ShoppingListId]];
//NSLog(#"new list :: RESPONSE FROM SERVER :: nList %#", [slist ShoppingListName]);
}
}
if ([mine isKindOfClass:[ListServiceSvc_GetProductsWithListIdResponse class]])
{
for (id products in [[mine GetProductsWithListIdResult] Product])
{
[prodForList setObject:[products ProductName] forKey:[products ShoppingListId]];
NSLog(#"new product :: RESPONSE FROM SERVER :: nList %#", [products ProductName]);
}
}
}
[self performSelectorOnMainThread:#selector(updateNewView:) withObject:shoppingListFromWebserver waitUntilDone:NO];
}
-(void) updateNewView:(NSMutableArray*) result
{
_shoppingList = result;
NSLog( #"new list - number of news :: %u", [_shoppingList count]);
[self.tableView reloadData];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1; // the number of different sections in your table view
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [_shoppingList count]; // the number of data in your shopping list
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ListCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
//cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
// Configure the cell...
id shopList = [_shoppingList objectAtIndex:indexPath.row];
cell.textLabel.text = [shopList ShoppingListName];
NSNumber *sid = [shopList ShoppingListId];
//[self loadItemsInList:sid];
NSNumber *prodcount = [prodForList objectForKey:sid];
NSString* pcTostring = [NSString stringWithFormat:#"%#", prodcount];
cell.detailTextLabel.text = pcTostring;
return cell;
The log actually tells me that I am getting some products for the last List it gets. Problem is that all cell.detailText.text fields are null, until the last reload, then all cells disappear.
I am pretty sure I'm doing it wrong, but I cant get my head around hot to get the products for the selected list, when I need to get the ShoppingListId from the -(void) loadListsFromRemoteServer call in order to do the -(void) loadItemsInList:(NSNumber*)slistId
WCF connection was made with the help of wsdl2obj
