copied!<p>I am getting a list of some <code>ShoppingLists</code> through a <code>WCF</code> call. </p> <p>My code: </p> <pre><code>#import "ListTableViewController.h" #import "ListServiceSvc.h" @interface ListTableViewController (){ // NSMutableArray *shoppingLists; } @property (nonatomic, retain) NSMutableArray *shoppingList; @end @implementation ListTableViewController - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { _shoppingList = [NSMutableArray array]; [self loadListsFromRemoteServer]; [super viewDidLoad]; } -(void) loadListsFromRemoteServer { NSString *uname = @"Test4"; NemListBinding *binding = [[ListServiceSvc NemListBinding]initWithAddress:@"http://balder.ucn.dk/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) operation:(NemListBindingOperation *)operation completedWithResponse:(NemListBindingResponse *)response { NSArray *responseHeaders = response.headers; NSArray *responseBodyParts = response.bodyParts; //[NSThread sleepForTimeInterval:5.0]; NSMutableArray *shoppingListFromWebserver = [[NSMutableArray 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]; NSLog(@"new list :: RESPONSE FROM SERVER :: nList %@", [slist ShoppingListName]); //self.result.text = [self.result.text stringByAppendingString:[slist shoppingListName]]; } } } [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 _shoppingList.count; //} //- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section //{ // // Return the number of rows in the section. // return 10; //} - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"cellforrow"); 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]; return cell; } </code></pre> <p>Nothing happens when i run the app in Xcode. I can see in the log window that the log </p> <pre><code>NSLog( @"new list - number of news :: %u", [_shoppingList count]); </code></pre> <p>does return a value <strong>(4)</strong>, but the <code>NSLog</code> i have made in the <code>CellForRowAtIndexPath</code> method does not get printed. I also have a breakpoint in there, that isn't reached. Why is it not getting to the method?</p>
