Hi,
You could use NSDefaults to store it. Something like
#define kLocationLat @"LOCATION_LAT"
#define kLocationLng @"LOCATION_LNG"
// Store the location
[[NSUserDefaults standardUserDefaults] setDouble:location.coordinate.lat forKey:kLocationLat];
[[NSUserDefaults standardUserDefaults] setDouble:location.coordinate.lng forKey:kLocationLng];
// Retrieve the location
CLLocationDegrees lat = [[NSUserDefaults standardUserDefaults] doubleForKey:kLocationLat];
CLLocationDegrees lng = [[NSUserDefaults standardUserDefaults] doubleForKey:kLocationLng];
CLLocation *location = [[CLLocation alloc] initWithLatitude:lat longitude:lng];

PS I don't have a mac to hand so there might be syntax errors in the above code but you get the idea :)
