Ios 谷歌地图缩小到GPS和标记
我试图在地图上展示三件事: GPS(当前位置)、标记1、标记2,但我不确定我是否做对了!这是我的密码:Ios 谷歌地图缩小到GPS和标记,ios,iphone,swift,xcode,google-maps,Ios,Iphone,Swift,Xcode,Google Maps,我试图在地图上展示三件事: GPS(当前位置)、标记1、标记2,但我不确定我是否做对了!这是我的密码: self.startMarker.position = CLLocationCoordinate2D(latitude: self.startLatitude, longitude: self.startLongitude) self.startMarker.icon = #imageLiteral(resourceName: "Pin Start") self.startMarker.
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
}
结果如下:
我需要的是:
已编辑
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))
}你能试试下面的代码吗,这是从ObjC代码转换过来的
显示屏幕绑定的所有标记:
let path = GMSMutablePath()
for var i in 0 ..< array.count //Here take your "array" which contains lat and long.
{
let marker = GMSMarker()
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))
在这里,我试图给你提供一个简单的例子,希望这将帮助你。
使用此功能,您可以在屏幕上显示任意数量的标记
示例:
let path = GMSMutablePath()
for var i in 0 ..< array.count //Here take your "array" which contains lat and long.
{
let marker = GMSMarker()
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))
let path=GMSMutablePath()
对于0..
注意:
let path = GMSMutablePath()
for var i in 0 ..< array.count //Here take your "array" which contains lat and long.
{
let marker = GMSMarker()
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))
locationArray
包含三个位置,即标记1、标记2和用户位置。对于正在寻找Objective-C解决方案的人,这可能会有所帮助
//Locations
CLLocationCoordinate2D source = CLLocationCoordinate2DMake(19.2880, 72.1587);
CLLocationCoordinate2D userLocation = CLLocationCoordinate2DMake(19.1780, 72.9577);
CLLocationCoordinate2D destination = CLLocationCoordinate2DMake(19.0760, 72.8777);
//Create a GMSMutablePath
GMSMutablePath *path = [GMSMutablePath new];
[path addCoordinate:source];
[path addCoordinate:userLocation];
[path addCoordinate:destination];
//Create bounds
GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc]initWithPath:path];
//Update the camera position
[mapview animateWithCameraUpdate:[GMSCameraUpdate fitBounds:bounds]];
请告诉我如何填充
array.count
?@Mc.Lover你看,如果你有不同的lat&long,如果你是从后端获得的,那么你可以直接使用它,或者通过添加lat&long创建你自己的数组并使用该数组。谢谢!但还是不行!请检查我编辑的代码好吗?我已经添加了一个答案。请检查,确保调用了didUpdateLocations()。
