    <p>I am calling a WCF service to display data in a UITableViewController.The code in the .m file is:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; [docTable setDataSource:self]; [docTable setDelegate:self]; } -(void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; EDViPadDocSyncService *service = [[EDViPadDocSyncService alloc]init]; EDVCategory *cat = [EDVCategory alloc]; cat.categoryId = [catId intValue]; [service getDocsByCatId:self action:@selector(getDocsByCatIdHandler:) category:cat]; [docTable reloadData]; } - (void) getDocsByCatIdHandler: (id)value { if([value isKindOfClass:[NSError class]]) { NSLog(@"%@", value); return; } if([value isKindOfClass:[SoapFault class]]) { NSLog(@"%@", value); return; } NSMutableArray* result = (NSMutableArray*)value; NSMutableArray *documentList = [[NSMutableArray alloc] init]; self.myDocList = [[NSMutableArray array] init]; for (int i = 0; i &lt; [result count]; i++) { EDVDocument *docObj = [[EDVDocument alloc]init]; docObj = [result objectAtIndex:i]; [documentList addObject:[docObj docName]]; } self.myDocList = documentList; [docTable reloadData]; } - (void)viewDidUnload { [super viewDidUnload]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { int cnt = [self.myDocList count]; NSLog(@"ABC=%@",cnt); return [self.myDocList count]; //return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { DocumentCell *cell = [tableView dequeueReusableCellWithIdentifier:@"DocumentCell"]; if (cell == nil) { cell = [[[DocumentCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"DocumentCell"] autorelease]; } NSLog(@"cell text=%@",[self.myDocList objectAtIndex:indexPath.row]); cell.lblDocName.text = [self.myDocList objectAtIndex:indexPath.row]; return cell; } </code></pre> <p>I am using storyboard.I have hooked the "docTable",set the datasource and the delegate for "docTable".The problem is,the service is called after the call to <strong>"numberOfRowsInSection"</strong>.So,<strong>'return [self.myDocList count]'</strong> is 0.I have put <strong>[docTable reloadData]</strong> in <strong>viewWillAppear</strong> as well as in the service handler,that is,<strong>"getDocsByCatIdHandler"</strong>.But it isn't getting reloaded,as expected.Is there anything else I can try? <strong>EDIT</strong>:- This a Master-Detail application.I have used the same code for loading data in the "MasterViewController" UITableViewController and it works.When the user selects a cell in this table,I need to populate data in the second tableview by calling the WCF service.The second tableview isn't displaying data.</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
