我在 ios 应用程序中使用了谷歌地图，我想动态设置缩放级别取决于我在地图上进行的搜索。基本上是通过搜索城市名称或纬度/经度查询来添加图钉。每次搜索后，我都会添加图钉，并且我需要通过我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))

有关迭代给定标记数组然后相应设置边界的简单方法，请参见此答案。
