ios - Fit entire Google Map in zoom level in Swift project -

-

i have google map bunch of coordinates

path.addcoordinate(cllocationcoordinate2dmake(-37.813047, 144.959911)) path.addcoordinate(cllocationcoordinate2dmake(-37.814895, 144.960759)) path.addcoordinate(cllocationcoordinate2dmake(-37.814361, 144.963140)) path.addcoordinate(cllocationcoordinate2dmake(-37.812386, 144.962239))

i map automatically zoomed best level based on points can't find relating this.

i have working:

var vancouver = cllocationcoordinate2dmake(-37.813047, 144.959911) var calgary = cllocationcoordinate2dmake(-37.814361, 144.963140) var bounds = gmscoordinatebounds(coordinate: vancouver, coordinate: calgary) var camera = viewmap.cameraforbounds(bounds, insets:uiedgeinsetszero) viewmap.camera = camera

however accepts 2 coordinates may have 100

thanks

you can use gmscoordinatebounds(path:) fit coordinates. display world size scale if update camera right after update. can use dispatch_after solve problem. 

 override func viewdidload() {         super.viewdidload()          self.view.backgroundcolor = uicolor.whitecolor();         let camera = gmscameraposition.camerawithlatitude(-37.813047, longitude: -72.8561644, zoom:5)         mapview = gmsmapview.mapwithframe(cgrectzero, camera:camera)          let marker = gmsmarker()         marker.position = camera.target         marker.snippet = "hello world"         marker.appearanimation = kgmsmarkeranimationpop         marker.map = mapview          self.view = mapview          delay(seconds: 2) { () -> () in             let path = gmsmutablepath()             path.addcoordinate(cllocationcoordinate2dmake(37.36, -122.0))             path.addcoordinate(cllocationcoordinate2dmake(37.45, -122.0))             path.addcoordinate(cllocationcoordinate2dmake(37.45, -122.2))             path.addcoordinate(cllocationcoordinate2dmake(37.36, -122.2))             path.addcoordinate(cllocationcoordinate2dmake(37.36, -122.0))              let rectangle = gmspolyline(path: path)             rectangle.map = self.mapview              let bounds = gmscoordinatebounds(path: path)              self.mapview!.animatewithcameraupdate(gmscameraupdate.fitbounds(bounds, withpadding: 15.0))         }     }

the delay method uses dispatch_after:

func delay(#seconds: double, completion:()->()) {     let poptime = dispatch_time(dispatch_time_now, int64( double(nsec_per_sec) * seconds ))      dispatch_after(poptime, dispatch_get_main_queue()) {         completion()     } }
