首先，当我设置区域地图视图时，放大并缩小工作正确。当我尝试使用自定义视图设置注释时，当我设置注释时，缩放不起作用。用户放大后，它会自动缩小。
请参阅下面的代码：
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)

您的mapKit视图保持缩小的原因是，在下面的函数中调用并保持“重置”您的区域。
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
}
