即時にMKMapviewが正しく機能しない

Question

まず、リージョンマップビューを設定すると、ズームインとズームアウトが正しく行われます。注釈をカスタムビューで設定しようとすると、注釈を設定すると、ズームが機能しません。ユーザーがズームインすると、自動的にズームアウトします。

は、以下の私のコードを参照してください：

 func setRegion(){ 
     var newRegion = MKCoordinateRegion() 
     //  let str = String(format: "%.01f", maxLoc) 
     //  maxdist = Double(str)! 
     let subscriberData = (SubscriberConfigDBHandler.SubConfigDBSharedInstance).getSubscriberUserDetails() 

     let latLanCoords :CLLocation = CLLocation(latitude:subscriberData.busLat as Double , longitude:subscriberData.busLng as Double) 
     newRegion.center.latitude = latLanCoords.coordinate.latitude 
     newRegion.center.longitude = latLanCoords.coordinate.longitude 
     newRegion.span.latitudeDelta = 0.075 
     newRegion.span.longitudeDelta = 0.075 
     self.liveTrackingMapView.setRegion(newRegion, animated: false) 

    } 

    private var mapChangedFromUserInteraction = false 

    private func mapViewRegionDidChangeFromUserInteraction() -> Bool { 
     let view = self.liveTrackingMapView.subviews[0]

      for recognizer in gestureRecognizers {

をごmapKitビューがズームアウトし続ける理由は、以下の機能に呼ばれ、お住まいの地域を「リセット」し続けることです。

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 
     guard let location = locations.last as CLLocation? else { return } 

     let userCenter = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude) 
     let region = MKCoordinateRegion(center: userCenter, span: MKCoordinateSpan(latitudeDelta: 180, longitudeDelta: 180)) 
     nameOfMapKitView.setRegion(region, animated: true) // THIS CAUSES MAP TO ZOOM OUT AGAIN 

}
