How it looks in XCODE
CODE OF MAP
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()
}
}
}
解决方法
我找到了答案
self.view.bringSubviewToFront(self.view_name)
您需要在父视图上调用bringSubviewToFront.
