current location too slow for view
- by Christian
Hi,
I make an App with a Map in the App and a button to change to the google.Map-App.
The code for my position is:
-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation {
float avgAccuracy = (newLocation.verticalAccuracy + newLocation.horizontalAccuracy)/2.0;
if (avgAccuracy < 500) {
[locationManager stopUpdatingLocation];
locationManager.delegate = nil;
}
storedLocation = [newLocation coordinate];
The code for the view is:
- (void)viewDidLoad {
[super viewDidLoad];
UIImage *image = [UIImage imageNamed: @"LogoNavBar.png"];
UIImageView *imageview = [[UIImageView alloc] initWithImage: image];
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView: imageview];
self.navigationItem.rightBarButtonItem = button;
[imageview release];
[button release];
locationManager=[[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
mapView.showsUserLocation = YES;
NSLog(@"storedLocation-latitude für MKregion: %f", storedLocation.latitude);
MKCoordinateRegion region;
region.center.latitude = (storedLocation.latitude + 45.58058)/2.0;
region.center.longitude = (storedLocation.longitude - 0.546835)/2.0;
region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058);
region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835);
[mapView setRegion:region animated:TRUE];
MKCoordinateRegion hotel;
hotel.center.latitude = 45.58058;
hotel.center.longitude = -0.546835;
HotelPositionMarker* marker = [[HotelPositionMarker alloc] initWithCoordinate:hotel.center];
[mapView addAnnotation:marker];
[marker release];
}
My problem: when the "viewDidLoad" start, the "storedLocation" is still 0.0000 it takes a bit longer to get the own position than to start the view. The Log for the "storedLocation" in the "viewDidLoad"-section is 0 while the Log of the "storedLocation" in the "-(IBAction)" when the map is visible contains the right values.
How can I manage it to have my coordinates before the view load? I need them to center the view concerning the own position and the position given by me.
MKCoordinateRegion region;
region.center.latitude = (storedLocation.latitude + 45.58058)/2.0;
region.center.longitude = (storedLocation.longitude - 0.546835)/2.0;
region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058);
region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835);
[mapView setRegion:region animated:TRUE];
