    <p>I'm creating a chat application. I have 2 methods in my view controller one for sending and one for receiving the messages. In the sending method i create a NSMutableDictionary with two objects ..</p> <pre><code>NSMutableDictionary *msgFilter = [[NSMutableDictionary alloc] init]; [msgFilter setObject:messageStr forKey:@"msg"]; [msgFilter setObject:@"you" forKey:@"sender"]; [messages addObject:msgFilter]; </code></pre> <p>"messages" is my main NSMutableArray for holding all the messages, whose property is set and synthesized and allocated. When i send the message it is properly added into the NSMutableArray and the UITableView is updated showing me the values in the cell. </p> <p>I have a method in my appDelegate to check for messages received and use the same procedure to parse the data and store it in an NSMutableDictionary. This dictionary is then passed to the viewcontroller and added into the same NSMutableArray(messages) and i then call [self.chattable reloadData]. But this doesn't do anything. When i nsloged the NSMutableArray it only had the received message not the whole data(send + received).</p> <h2>Why is it not adding the received messages into the same array and why is it not refreshing my table. I've been trying to get it to work for days now...Plz help..</h2> <p>//Recives message section</p> <pre><code>NSMutableDictionary *msgFilter = [myDelegate msgFilter]; [messages addObject:msgFilter]; [self.tView reloadData]; </code></pre> <p>//Tableview section</p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [messages count]; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; } NSDictionary *s = (NSDictionary *) [messages objectAtIndex:indexPath.row]; NSString *sender = [s objectForKey:@"sender"]; NSString *message = [s objectForKey:@"msg"]; if ([sender isEqualToString:@"you"]) { cell.detailTextLabel.text = [NSString stringWithFormat:@"TX: %at", message]; } else { cell.detailTextLabel.text = [NSString stringWithFormat:@"RX: %at", message]; } return cell; } </code></pre>

    3. COEverything seems right, are you sure self.tView is not nil? Place a log before the reloadData.

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.
