Um den Standort des Nutzers zu erhalten müssen Sie eigentlich „Start“ den Standort-Manager, bevor Sie die Standort-Informationen zu lesen. Ich schlage vor, dass Sie bei LocateMe Probe von Apple aussehen.
LocateMe Beispielcode
Auf den Punkt gebracht, kann immer Benutzer-Standortinformationen in zwei Schritten erfolgen:
- (void)viewDidLoad {
[[self locationManager] startUpdatingLocation];
}
- (CLLocationManager *)locationManager {
if (locationManager != nil) {
return locationManager;
}
NSLog(@"%s, Creating new Location Manager instance.", __FUNCTION__);
locationManager = [[CLLocationManager alloc] init];
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = DISTANCE_FILTER_VALUE;
locationManager.delegate = self;
return locationManager;
}
... und dann,
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
NSLog(@"%s, location manager returned a new location.", __FUNCTION__);
// Check if location is valid (or good enough for us),
// and then process the location
if ([self locationIsValid:newLocation]) {
[self processLocation:newLocation];
// Very important! When your done with it, stop the location manager
[[self locationManager] sopUpdatingLocation];
// (Maybe even) clear it
locationManager.delegate = nil;
[locationManager release];
locationManager = nil;
}
}
Hoffe das hilft!
