    <p>I'm calling a webservice in <code>viewDidLoad</code> method of tableViewcontroller class and parsing the data in another class as follows</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; dataWebService = [[NSMutableData data] retain]; NSString *authString = [[[NSString stringWithFormat:@"%@:%@",@"admin", @"admin"] dataUsingEncoding:NSUTF8StringEncoding] base64Encoding]; NSMutableURLRequest *request = [[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://172.16.3.47:8980/opennms/rest/alarms?limit=5"]] retain]; [request setValue:[NSString stringWithFormat:@"Basic %@",authString] forHTTPHeaderField:@"Authorization"]; [[NSURLConnection alloc] initWithRequest:request delegate:self]; // Uncomment the following line to display an Edit button in the navigation bar for this view controller. // self.navigationItem.rightBarButtonItem = self.editButtonItem; } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [dataWebService setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [dataWebService appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"Eror during connection: %@", [error description]); } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; NSString* responseString = [[NSString alloc] initWithData:dataWebService encoding:NSUTF8StringEncoding]; AlarmWSParse* alarmParser = [[AlarmWSParse alloc]init]; severity = [alarmParser xmlParser:responseString]; NSLog(@"no of elements in array %d",[severity count]); NSLog(@"Back to Alarm List View controller and severtiy array is %@",severity); } </code></pre> <p>and then setting this severity array value in table cell as </p> <pre><code>- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections. return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the section. return [severity count]; } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
