Question

When I enable (uncomment) this line of code I get a SIGABRT crash – which is strange, to me, because I have never had this issue before.

cell.textLabel.text = [[annotations objectAtIndex:indexPath.row] title];

The error I get is:

2011-12-28 14:03:00.118 MapWithTableModalView-001[2006:11603] Localized name database is not present
2011-12-28 14:03:01.110 MapWithTableModalView-001[2006:11603] * Terminating app due to uncaught exception ‘NSRangeException’, reason: ‘* -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array’

The project produces no errors or warnings.

The project is based on 2 UIViewControllers that slide on top of each other via a button – ModalViewContoller. When I press the button, the crash happens.

Just adding the code here – it is part of a tutorial, but I still want to get it:-) I know this does not look like an ordinary array, but the data is set like this in the project. Once I figure this out I want to set it in a Plist.

-(void)loadOurAnnotations
    {
CLLocationCoordinate2D workingCoordinate;


    #pragma mark - Apple Stores
workingCoordinate.latitude = 51.514298;
workingCoordinate.longitude = -73.973034;
iCodeBlogAnnotation *appleStore1 = [[iCodeBlogAnnotation alloc]     initWithCoordinate:workingCoordinate];
    [appleStore1 setTitle:@"Apple Store 5th Ave."];
[appleStore1 setSubtitle:@"Apple's Flagship Store"];
[appleStore1 setAnnotationType:iCodeBlogAnnotationTypeApple];

[viewController.mapView addAnnotation:appleStore1];

workingCoordinate.latitude = 51.514298;
workingCoordinate.longitude = -0.141949;
iCodeBlogAnnotation *appleStore2 = [[iCodeBlogAnnotation alloc] initWithCoordinate:workingCoordinate];
[appleStore2 setTitle:@"Apple Store St. Regent"];
[appleStore2 setSubtitle:@"London England"];
[appleStore2 setAnnotationType:iCodeBlogAnnotationTypeApple];

[viewController.mapView addAnnotation:appleStore2];



     }

If you would like me to post any additional code, I would be happy to, but I am not sure where to look anymore and hence don’t really know which bit to post to be helpful.

Your annotations array is empty (has zero elements).

Looking at your -loadOurAnnotations method, you never actually seem to set the annotations array that you’re reading. Try updating that line to something like below and see if that helps:

// I'm not sure where viewController comes from but I'll assume it's a method on this
// class and that it's the same class that defines -loadOurAnnotations. If it's not,
// update this appropriately to get access to the mapView to which you've added
// the annotations
cell.textLabel.text = [[[[viewController mapView] annotations] objectAtIndex:indexPath.row] title];
