当前位置 swift iOS 9

Question

我在 plist 中添加了 NSLocationWhenInUseUsageDescription 并将其设置为 YES，这是我的代码：

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let location = locations.last

    let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
    let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))

    self.mapView.setRegion(region, animated: true)

    print(location)
    print(center)

}

但是还是不行。它只是不显示任何内容。看起来 locationManager 函数从未被调用过。它甚至不打印任何记录。

Answer 1

刚刚通过添加解决了它：

 locationManager = CLLocationManager()
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestAlwaysAuthorization()
    locationManager.startUpdatingLocation()

并将 locationManager 声明为 class 变量。 var locationManager:CLLocationManager!
