ios谷歌地图-如何在不缩放相机的情况下获取我的设备位置

我正在按下按钮,以便定期获取我的位置。当涉及到实现时,该设备将让谷歌地图相机定期成为地图的中心,即使不使用GMSCameraUpdate进行对焦。请您告诉我要增强哪些功能,以便我们可以在不进行相机缩放的情况下定期获取更新的设备位置,好吗?

以下是我在onClick后触发缩放的工作

 if(self.myMapView.myLocation !=nil){
        [self.locationManager stopUpdatingLocation];
        [CATransaction begin];
        [CATransaction setAnimationDuration:0.2];
        GMSCameraUpdate *move = [GMSCameraUpdate setTarget:self.myMapView.myLocation.coordinate  zoom:self.myMapView.camera.zoom];
        [self.myMapView animateWithCameraUpdate:move];
        [CATransaction commit];
    }

获取位置后委派

- (void)locationManager:(CLLocationManager *)manager
     didUpdateLocations:(NSArray *)locations{
    CLLocation *location = [locations lastObject];


    if(location==nil){
        location = self.myMapView.myLocation;
    }

    myDeviceLocation = location;

    NSLog(@"adasdads zoom ");
    if (markera == nil) {
        markera = [[GMSMarker alloc] init] ;
        markera.position   = CLLocationCoordinate2DMake(22.2855200, 114.1576900);
        markera.groundAnchor = CGPointMake(0.5f, 0.97f); // Taking into account walker's shadow

        markera.map = self.myMapView;


    }else {
        [CATransaction begin];
        [CATransaction setAnimationDuration:2.0];
        markera.position = location.coordinate;
        markera.icon = nil;
        [CATransaction commit];

    }

    GMSCameraUpdate *move = [GMSCameraUpdate setTarget:location.coordinate zoom:17];
    [self.myMapView animateWithCameraUpdate:move];
}



-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)statusX {

    NSLog(@"status  : %d" , statusX);
    if (status == kCLAuthorizationStatusDenied) {
        //location denied, handle accordingly
        NSLog(@"denied ");

    }
else if (statusX == kCLAuthorizationStatusAuthorized) {
    //hooray! begin startTracking
    NSLog(@"proceed ");
    dispatch_async(dispatch_get_main_queue(), ^{
        self.myMapView.myLocationEnabled = YES;
    });



}else   if (statusX == kCLAuthorizationStatusAuthorizedAlways || statusX == kCLAuthorizationStatusAuthorizedWhenInUse) {
    self.myMapView.myLocationEnabled = YES;

    NSLog(@"gogogo ");
    dispatch_async(dispatch_get_main_queue(), ^{
      //  self.myMapView.myLocationEnabled = YES;
    });
