[英]Is it possible to find user current location in offline by using mapbox SDK in ios
我正在離線地圖上工作。 我正在使用Mapbox SDK。
但是我無法跟蹤用戶的當前位置。
我寫了code like below :
(void)viewDidLoad {
[super viewDidLoad];
RMMBTilesSource *offlineSource = [[RMMBTilesSource alloc] initWithTileSetResource:@"control-room-0.2.0" ofType:@"mbtiles"];
RMMapView *mapView = [[RMMapView alloc] initWithFrame:self.view.bounds andTilesource:offlineSource];
mapView.zoom = 2;
[self.view addSubview:mapView];
mapView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
mapView.adjustTilesForRetinaDisplay = YES; // these tiles aren't designed specifically for retina, so make them legible
[mapView setUserTrackingMode:RMUserTrackingModeFollow animated:true];
mapView.draggingEnabled = YES;
mapView.showsUserLocation = YES;
mapView.userInteractionEnabled = YES;
[self.view addSubview:mapView];
}
提前致謝。 請幫助我
實際上您可以做到,但是您必須打開wifi和3g網絡。 但是,如果showsUserLocation不適合您,則可以使用CLLocationManager進行操作。 希望我的代碼可以為您提供幫助。
- (IBAction)findMe:(id)sender {
if (!_trackingActive) {
NSLog(@"Tracking mode activated");
_locationManager = [[CLLocationManager alloc] init];
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
_locationManager.delegate = self;
[_locationManager startUpdatingLocation];
_startLocation = nil;
_trackingActive = true;
self.mapView.showsUserLocation = YES;
if ([UIView instancesRespondToSelector:@selector(setTintColor:)])
self.mapView.tintColor = [UIColor colorWithRed:0.200 green:1.000 blue:0.200 alpha:1];
self.mapView.userLocation.title = @"Hola";
self.mapView.userLocation.badgeIcon = [UIImage imageNamed:@"info"];
self.mapView.userLocation.annotationIcon = [UIImage imageNamed:@"info"];
}else{
NSLog(@"Tracking mode deactivated");
[_locationManager stopUpdatingLocation];
_trackingActive = false;
self.mapView.showsUserLocation = NO;
}
}
-(void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
NSString *currentLatitude = [[NSString alloc]
initWithFormat:@"%+.6f",
newLocation.coordinate.latitude];
_latitude.text = currentLatitude;
NSString *currentLongitude = [[NSString alloc]
initWithFormat:@"%+.6f",
newLocation.coordinate.longitude];
_longitude.text = currentLongitude;
NSString *currentHorizontalAccuracy =
[[NSString alloc]
initWithFormat:@"%+.6f",
newLocation.horizontalAccuracy];
_horizontalAccuracy.text = currentHorizontalAccuracy;
NSString *currentAltitude = [[NSString alloc]
initWithFormat:@"%+.6f",
newLocation.altitude];
_altitude.text = currentAltitude;
NSString *currentVerticalAccuracy =
[[NSString alloc]
initWithFormat:@"%+.6f",
newLocation.verticalAccuracy];
_verticalAccuracy.text = currentVerticalAccuracy;
if (_startLocation == nil)
_startLocation = newLocation;
CLLocationDistance distanceBetween = [newLocation
distanceFromLocation:_startLocation];
NSString *tripString = [[NSString alloc]
initWithFormat:@"%f",
distanceBetween];
_distance.text = tripString;
self.mapView.centerCoordinate = CLLocationCoordinate2DMake(currentLatitude.doubleValue, currentLongitude.doubleValue);
