[英]How to set visible region/zoom level for google maps IOS to show all markers added to the mapview
I have used Google maps in ios app, I wanna set zoom level dynamically depends on the search i made over map. 我在ios应用程序中使用了Google地图,我想动态设置缩放级别取决于我在地图上进行的搜索。 Basically am adding pins by searching with city names or lat/long query. 基本上我通过搜索城市名称或纬度/经度查询来添加引脚。 after every search am adding pins & i need to show all added markers by the recent search i made. 每次搜索后都添加了针脚,我需要通过最近的搜索显示所有添加的标记。
@IBOutlet weak var mapView: GMSMapView!
let camera = GMSCameraPosition.cameraWithLatitude(23.0793, longitude:
72.4957, zoom: 5)
mapView.camera = camera
mapView.delegate = self
mapView.myLocationEnabled = true
*** arry has dictionary object which has value of Latitude and Longitude. ***
let path = GMSMutablePath()
for i in 0..<arry.count {
let dict = arry[i] as! [String:AnyObject]
let latTemp = dict["latitude"] as! Double
let longTemp = dict["longitude"] as! Double
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: latTemp, longitude: longTemp)
marker.title = "Austrilia"
marker.appearAnimation = kGMSMarkerAnimationNone
marker.map = self.mapView
path.addCoordinate(CLLocationCoordinate2DMake(latTemp, longTemp))
}
let bounds = GMSCoordinateBounds(path: path)
self.mapView!.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds, withPadding: 50.0))
