Hi everybody,

I am using a MapView to display the position of a property. These coordinates will eventually be pulled from a database, so I'm not using CoreLocation to return a coordinate in this part of the app.

Here is my code:

	CLLocationCoordinate2D coord;
	coord.longitude = (CLLocationDegrees)[rp.locLat doubleValue];
	coord.latitude = (CLLocationDegrees)[rp.locLng doubleValue];
	
	UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Title" message:[[NSString alloc]initWithFormat:@"%f, %f", [rp.locLat doubleValue], [rp.locLng doubleValue]] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
	[alert show];
	[alert release];
	
	MKCoordinateRegion region;
    region.center = coord;
    MKCoordinateSpan span = {1, 1};
    region.span = span;
    mapView.region = region;

Just so you are aware, rp.locLat and rp.locLng are both of type NSString and hardcoded to 53.478239, -2.246704 respectively. If you enter this in maps.google.com it will display a pointer in Manchester, UK. This is correct.

However, the MapView centres the map just off the coast of the Seychelles which is obviously not correct. Initially I thought maybe it doesn't want a decimal representation of the lat/lng so I got the CoreLocation functionality to spit out a lat/lng for the devices current position.

The UIAlertView above displays the text: "53.478239, -2.246704", so I know that the values stored in the rp object are correct.

This gives me 37.332..., -122.031... (Apples HQ, which is correct). You can enter these values into maps.google.com and it gives you the correct position so I can assume my values are in the correct format.

The only thing I can think of is these lines:

Code:

	coord.longitude = (CLLocationDegrees)[rp.locLat doubleValue];
	coord.latitude = (CLLocationDegrees)[rp.locLng doubleValue];

are somehow corrupting the values passed to the coord object. I've no clue why though, so any ideas would be most welcome - especially since I am using the same values in the UIAlertView which are displaying exactly how i'd expect...

I'm stumped, so if anyone has any ideas at all that would be great.

Cheers,
Dave

Oh my god, never mind I'm a FOOL.

I was assigning the longitude to the latitude property, and the latitude to the longitude property.

Mods feel free to delete this utterly pointless thread I started. My apologies.
