我为mapView起诉swift编写了一个简单的示例，但得到了Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.打印信息
我将mapView添加到viewController并开始位置。我也叫requestWhenInUseAuthorization()在startUpdatingLocation()之前
我设置了Info.plist
现在我同时设置了NSLocationAlwaysUsageDescription和NSLocationWhenInUseUsageDescription，它不起作用。
Tere是我的代码，怎么了？
class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {
var locationManager: CLLocationManager?
var mapView: MKMapView?
override func viewDidLoad() {
super.viewDidLoad()
let locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.distanceFilter = 10
locationManager.delegate = self
locationManager.pausesLocationUpdatesAutomatically = true
if CLLocationManager.locationServicesEnabled() {
let status: CLAuthorizationStatus = CLLocationManager.authorizationStatus()
if status == CLAuthorizationStatus.NotDetermined {
if #available(iOS 8.0, *) {
locationManager.requestWhenInUseAuthorization()
}
}
locationManager.startUpdatingLocation()
self.locationManager = locationManager
} else {
print("locationServices disenabled")
}
let mapview = MKMapView(frame: self.view.bounds)
mapview.mapType = .Standard
mapview.showsUserLocation = true
mapview.delegate = self
self.mapView = mapview
self.view.addSubview(mapview)
}
}
最佳答案
警告提示您在plist中缺少两个必需的字符串之一
NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription
