我在ios app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。基本上我通过搜索城市名称或纬度/经度查询来添加引脚。在每次搜索之后我都会添加pin&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))

See this answer以一种简单的方式迭代给定的标记数组,然后相应地设置边界。
