  1. POWCF call nested in a WCF call
    text
    copied!<p>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:</p> <pre><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; </code></pre> <p>The log actually tells me that I am getting some products for the last List it gets. Problem is that all <code>cell.detailText.text</code> fields are null, until the last reload, then all cells disappear.</p> <p>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 <code>-(void) loadListsFromRemoteServer</code> call in order to do the <code>-(void) loadItemsInList:(NSNumber*)slistId</code></p> <p>WCF connection was made with the help of wsdl2obj</p>
