屏幕不缩放到右坐标-快速谷歌地图api

使用GMSMap获取动态谷歌地图时，地图不会显示我给他的当前位置，也不会缩放地图
import UIKit
import GoogleMaps
import MapKit
class LocationItemViewController: UIViewController,GMSMapViewDelegate, CLLocationManagerDelegate {
@IBOutlet weak var lblInfo: UILabel!
@IBOutlet weak var lblTitle: UILabel!
@IBOutlet weak var viewMap: UIView!
@IBOutlet weak var googleMapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
let latitude = (String(format:"%.02f", locationItem.itemLatitude ) as NSString).doubleValue
let longgitude = (String(format:"%.02f", locationItem.itemLongitude) as NSString).doubleValue
let camera = GMSCameraPosition.cameraWithLatitude(latitude,longitude: longgitude, zoom: 7)
let mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
mapView.myLocationEnabled = true
self.googleMapView = mapView
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake((locationItem.itemLatitude as NSString).doubleValue, (locationItem.itemLongitude as NSString).doubleValue)
marker.title = "somelocation"
marker.snippet = "anywhere"
marker.map = mapView
lblTitle.text = locationItem.itemName
lblInfo.text = locationItem.itemAddress
}我在app委托中找到了GMSServices.provideAPIKey("YOUR_API_KEY")

要显示您当前的位置，您必须执行与苹果地图相同的操作才能访问我们的位置。
在plist中，您必须添加2个条目并获得用户的许可。
- NSLocationWhenInUseUsageDescription
- NSLocationAlwaysUsageDescription

现在关于你的谷歌地图缩放问题
var mapView:GMSMapView?现在在你的viewDidLoad
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
GMSServices.provideAPIKey("YOUR_API_KEY")
//Taking HardCoded lat longs for the time being. These lat longs are of New Delhi, India
let camera = GMSCameraPosition.cameraWithLatitude(28.6139, longitude: 77.2090, zoom: 10)
mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
mapView!.myLocationEnabled = true
self.view = mapView
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake(28.6139, 77.2090)
marker.title = "Delhi"
marker.snippet = "India"
marker.map = mapView
//As view takes some time to load so I am calling my zoom function after a delay of 1 second. You can use the zoom function code in viewDidAppear too
//Also this syntax is the latest Swift 2.2 syntax. If you are using the old Swift version, make the changes accordingly for performSelector method
self.performSelector(#selector(zoom), withObject: nil, afterDelay: 1.0)
}这是变焦法
func zoom() {
CATransaction.begin()
CATransaction.setValue(1, forKey: kCATransactionAnimationDuration)
// It will animate your camera to the specified lat and long
let camera = GMSCameraPosition.cameraWithLatitude(28.6139, longitude: 77.2090, zoom: 15)
mapView!.animateToCameraPosition(camera)
CATransaction.commit()
