地图编码

import UIKit
import GoogleMaps

class HomeViewController: UIViewController, CLLocationManagerDelegate {
    @IBOutlet weak var scrollView: UIScrollView!
    @IBAction func refreshLocation(sender: AnyObject) {
        locationManager.startUpdatingLocation()

    }
@IBOutlet weak var gMapView: GMSMapView!


let locationManager = CLLocationManager()




override func viewDidLoad() {
    super.viewDidLoad()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation
    locationManager.requestAlwaysAuthorization()
  locationManager.startUpdatingLocation()
    self.scrollView.contentSize=CGSizeMake(320, 700)


            let camera = GMSCameraPosition.cameraWithLatitude(15.4989, longitude: 73.8278, zoom: 17)

            gMapView.camera = camera
            gMapView.myLocationEnabled = true

            self.view.addSubview(gMapView)
            let marker = GMSMarker()

            marker.map = self.gMapView

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

}

extension HomeViewController {
    func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        if status == CLAuthorizationStatus.AuthorizedAlways {
            locationManager.startUpdatingLocation()

        gMapView.myLocationEnabled = true

        gMapView.settings.myLocationButton = true
    }
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location = locations.first {
        gMapView.camera = GMSCameraPosition(target: location.coordinate, zoom: 15, bearing: 0, viewingAngle: 0)

        locationManager.stopUpdatingLocation()

    }
}



}

我找到了答案

self.view.bringSubviewToFront(self.view_name)

您需要在父视图上调用bringSubviewToFront.
