I have got a problem with a CLLocation.
I wanted to know the distance between two coordinates to show it next to the title of the location in a tableView: static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
}
// The first CLLocation based on the coordinates my MKMapView gives me.
CLLocation *userLocation = [[CLLocation alloc] initWithLatitude:mapView.userLocation.coordinate.latitude longitude:mapView.userLocation.coordinate.longitude];
// The second CLLocation based on the coordinates which are saved as a NSNumber in my own object
CLLocation *locationForIndex = [[CLLocation alloc] initWithLatitude:[[[locations objectAtIndex:indexPath.row] latitude] do开发者_运维百科ubleValue] longitude:[[[locations objectAtIndex:indexPath.row] longitude] doubleValue]];
CLLocationDistance distance = [userLocation distanceFromLocation:locationForIndex];
cell.textLabel.text = [[locations objectAtIndex:indexPath.row] title];
cell.detailTextLabel.text = [[NSString alloc] initWithString:[NSString stringWithFormat:@"%d", distance]];
return cell;
Now the error I get is:
Does anyone has a possible solution?
Thanks!!
Have you included the Core Location framework along with MapKit?
