我试图在地图上显示三件事情：
GPS(当前位置),Marker 1,Marker 2,但我不知道我做得对不对！这是我的代码：
GPS(当前位置),Marker 1,Marker 2,但我不知道我做得对不对！这是我的代码：
self.startMarker.position = CLLocationCoordinate2D(latitude: self.startLatitude,longitude: self.startLongitude) self.startMarker.icon = #imageLiteral(resourceName: "Pin Start") self.startMarker.map = self.mapView self.endMarker.position = CLLocationCoordinate2D(latitude: self.endLatitude,longitude: self.endLongitude) self.endMarker.icon = #imageLiteral(resourceName: "Pin End") self.endMarker.map = self.mapView let southWest = CLLocationCoordinate2DMake(self.startLatitude,self.startLongitude) let northEast = CLLocationCoordinate2DMake(self.endLatitude,self.endLongitude) let bounds = GMSCoordinateBounds(coordinate: northEast,coordinate: southWest) let camera = self.mapView.camera(for: bounds,insets:.zero) self.mapView.camera = camera!
更多代码：
// MARK: - Google Map
private func locationManager(manager: CLLocationManager,didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == CLAuthorizationStatus.authorizedWhenInUse {
mapView.isMyLocationEnabled = true
}
}
func locationManager(_ manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
let newLocation = locations.last
mapView.camera = GMSCameraPosition.camera(withTarget: newLocation!.coordinate,zoom: 14)
mapView.isMyLocationEnabled = true
}
结果是这样的：
我需要的 ：
EDITED
if let myLocation = self.mapView.myLocation {
let path = GMSMutablePath()
path.add(myLocation.coordinate)
path.add(self.startMarker.position)
path.add(self.endMarker.position)
let bounds = GMSCoordinateBounds(path: path)
self.mapView.animate(with: GMSCameraUpdate.fit(bounds,withPadding: 40))
}
解决方法
显示屏幕界限的所有标记：
在这里我试图给你一个简单的例子,希望这将有助于你.
使用此功能,您可以在屏幕上显示任意数量的标记.
例：
let path = GMSMutablePath()
for var i in 0 ..< array.count
{
let lat = Double(array.objectAtIndex(i).valueForKey(lattitude) as! String)
let long = Double(arrayr.objectAtIndex(i).valueForKey(longitude) as! String)
marker.position = CLLocationCoordinate2DMake(lat!,long!)
path.addCoordinate(marker.position)
marker.map = self.mapView
}
let bounds = GMSCoordinateBounds(path: path)
self.mapView!.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds,withPadding: 30.0))
