Ios Swift，谷歌地图适合所有标记

我想在谷歌地图窗口中自动缩放所有标记

下面是我的代码

func loadGoogleMap()
{

    dispatch_async(dispatch_get_main_queue(),
        {
            self.googleMapView.clear()

            self.googleMapView.delegate = self
            var visibleRegion : GMSVisibleRegion = self.googleMapView.projection.visibleRegion()
            var bounds = GMSCoordinateBounds(coordinate: visibleRegion.nearLeft, coordinate: visibleRegion.nearRight)
            var count = 1
            for Prop: Property in self.properties
            {
                if Prop.propLat != ""
                {

                   //  println("lat >>  \(Prop.propLat) lang >> \(Prop.propLang)")
                    var latStr = Prop.propLat
                    var latDbl : Double  = Double(latStr.floatValue)
                    var langStr = Prop.propLang as NSString
                    var langDbl : Double = Double(langStr.floatValue)
                    var marker = GMSMarker()

                    if count == 0
                    {
  //                           let initialLocation =   CLLocationCoordinate2DMake(langDbl,latDbl)
   //                            let initialDirection = CLLocationDirection()
    //                            
    //                            let camera = GMSCameraPosition.cameraWithTarget(initialLocation, zoom: 5)
    //                            self.googleMapView.camera = camera
    //                            
                    }

                    marker.position = CLLocationCoordinate2DMake(langDbl,latDbl)
                    marker.appearAnimation = kGMSMarkerAnimationPop
                    marker.icon = UIImage(named: "red_\(Prop.propSequence)")
                    marker.title = Prop.propBuildingName as String
                    marker.snippet = Prop.propCode as String
                    marker.infoWindowAnchor = CGPointMake(0.44, 0.45);
                    bounds.includingCoordinate(marker.position)
                    marker.map = self.googleMapView
                    count++

                }

            }

            self.googleMapView.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds, withPadding: 30.0))

    })

   }

上面的swift代码被添加到view WILLEXEEN和viewdidload方法中。

有人能帮我找出上面代码中的错误吗。

在您使用的代码中：

---

var bounds=GMSCoordinateBounds（坐标：visibleRegion.nearLeft，坐标：visibleRegion.nearRight）

您保存了我的一天

@IBOutlet weak var viewMap: GMSMapView!
var markers = [GMSMarker]()
var bounds = GMSCoordinateBounds()
    for marker in self.markers {
        bounds = bounds.includingCoordinate(marker.position)
    }
    viewMap.animate(with: GMSCameraUpdate.fit(bounds, with: UIEdgeInsetsMake(50.0 , 50.0 ,50.0 ,50.0)))
