    <p>I'm a beginner but have been working really hard to build this application. Working from another question I asked: <a href="https://stackoverflow.com/questions/5319669/mapkit-and-table-view-sample-code-iphone-sdk">mapkit and table view sample code - iPhone SDK</a></p> <p>I was able to put together a (semi-)functioning tableview and mapview. However, I'm not really sure how to call the mapview annotations to do numberOfRowsInSection or cellForRowAtIndexPath.</p> <p>the cellForRowAtIndexPath I'm sure isn't called properly but I'm thinking its a combo of both numberOfRowsInSection and cellForRowAtIndexPath.. But honestly I've been trying (and failing) for 3 weeks and reading all I can before I asked the question.</p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { //return [[mapView annotations] count]; return 1; } </code></pre> <p>So I was trying to use the count of the mapview annotations but I'm not even sure if this is working. </p> <pre><code>-(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]autorelease]; } NSMutableArray *annotations = [[NSMutableArray alloc] init]; //i'm sure the entire block below is pretty awful but i'm at a standstill for (MapLocation *annotation in [mapView annotations]) { [annotations addObject:annotation]; cell.textLabel.text = [[annotations objectAtIndex:indexPath.row]title]; } return cell; //i'm pretty sure this shouldn't be here </code></pre> <p>}</p> <p>If any other code is needed to help explain my situation just let me know.</p>

    1. COAre the tableView and mapView in the same view controller? What happens if you uncomment that line in numberOfRowsInSection? How exactly is it failing? Is there a compile error, run-time error?

    2. COwould only be able to get 1 annotation to come into the tableview without it crashing on startup. It took me a few days but I've solved the issue but the numberOfRowsInSection still isn't very dynamic but I can live with it. I'll post my solution below.

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.
