我必须在Google Map视图中绘制多个针脚,然后缩放到用户的当前位置。引脚已成功绘制,但未缩放到当前位置。任何帮助,将不胜感激谷歌地图不缩放到我目前的位置
override func viewDidAppear(_ animated: Bool) {
if (self.googleMapsView == nil) {
self.googleMapsView = GMSMapView(frame: self.mapViewContainer.frame)
self.view.addSubview(self.googleMapsView)
print(AppDelegate.getAppDelegate().mapArray)
googleMapsView.clear()
for i in 0...AppDelegate.getAppDelegate().mapArray.count - 1 {
let lon = Double ((AppDelegate.getAppDelegate().mapArray[i]["lon"] as? String)!)
let lat = Double ((AppDelegate.getAppDelegate().mapArray[i]["lat"] as? String)!)
let tit = AppDelegate.getAppDelegate().mapArray[i]["location"] as? String
locateWithLongitude(lon: lon!,andLatitude: lat! ,andTitle: tit!)
}
let marker = GMSMarker(position: AppDelegate.getAppDelegate().myLocation)
let camera = GMSCameraPosition.camera(withLatitude: AppDelegate.getAppDelegate().myLocation.latitude, longitude: AppDelegate.getAppDelegate().myLocation.longitude, zoom: 11)
self.googleMapsView.camera = camera
marker.title = AppDelegate.getAppDelegate().sublocality
marker.map = self.googleMapsView
self.googleMapsView.animate(to: camera)
}
}
func locateWithLongitude(lon: Double, andLatitude lat: Double, andTitle title: String) {
DispatchQueue.main.async() {() -> Void in
let position = CLLocationCoordinate2DMake(lat, lon)
let marker = GMSMarker(position: position)
let camera = GMSCameraPosition.camera(withLatitude: lat, longitude: lon, zoom: 0)
self.googleMapsView.camera = camera
marker.title = title
marker.map = self.googleMapsView
}
}
你能解释一下你在做什么?因为你可以多次调用放大缩小,因为我可以看到,如果你可以解释一点,我们可以更容易地帮你 –
我已经在地图上绘制了多个注解并缩放到当前位置 –
你只需要缩放到当前位置或几个地点在一个又一个? –
