    <p>I am new to iPhone apps and objective c and I cannot figure out what is wrong with my method the general idea is that it goes to a plist which contain latitudes and longitudes, takes the data stored in the array that the user enters in a text field, and then outputs a pin at that location. Any suggestions would be greatly appreciated. I have only posted the code for the method, but if having any other part of the application would help in debugging my code then I'd be happy to post it.</p> <pre><code>-(IBAction) showBus { [busNum resignFirstResponder]; bus *currentBus = [[bus alloc] init]; NSString *txtFieldData = [[NSString alloc] initWithString: busNum.text]; //get data from plist NSString *myFile = [[NSBundle mainBundle] pathForResource:@"busLocations" ofType:@"plist"]; NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile: myFile]; [myFile release]; [currentBus setLat:[[dictionary objectForKey:txtFieldData] objectAtIndex:0]]; [currentBus setLong:[[dictionary objectForKey:txtFieldData] objectAtIndex:1]]; //[currentBus setName:[[dictionary objectForKey:txtFieldData] objectAtIndex:2]]; [txtFieldData release]; [dictionary release]; int latit = [[currentBus Lat] intValue]; int longit = [[currentBus Long] intValue]; NSLog(@"latitude is %d and longitude is %d",latit,longit); /* [mapView setMapType:MKMapTypeStandard]; [mapView setZoomEnabled:YES]; [mapView setScrollEnabled:YES]; */ MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = latit; region.center.longitude = longit; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [mapView setRegion:region animated:YES]; [mapView setDelegate:self]; DisplayMap *ann = [[DisplayMap alloc] init]; ann.title = @"Bus %@",[currentBus name]; ann.coordinate = region.center; [mapView addAnnotation:ann]; //[ann release]; [currentBus release]; } </code></pre> <p>Thanks for the help</p>

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.
