我已经设置了一个自定义mapView并将其全屏显示在我的视图控制器上。初始化mapView时,它将检查位置授权,如果授予则转showsUserLocation = true
我可以在控制台中输入经过授权后会击中该标志并将其变为true的情况,并且mapView将正确运行我的centerViewOnUserLocation()方法,但是我仍然看不到地图上的蓝点作为位置。我在iPhone上而不是模拟器上进行测试。下面是一些代码示例:
视图控制器
private lazy var mapView: EVMapView = {
let result: EVMapView = EVMapView()
view.addSubview(result)
result.delegate = self
EVConstraintHelper.anchor(view: result, options: .classic)
return result
}()
自定义MapView
class EVMapView: MKMapView, EVLocationProtocol {
var locationManager: CLLocationManager?
init() {
super.init(frame: .zero)
checkLocationServices()
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func checkLocationServices() {
if CLLocationManager.locationServicesEnabled() {
setupLocationManager()
checkLocationAuth()
} else {
print("Auth Denied")
}
}
func setupLocationManager() {
locationManager = CLLocationManager()
locationManager?.delegate = self
locationManager?.desiredAccuracy = kCLLocationAccuracyBest
}
func checkLocationAuth() {
switch CLLocationManager.authorizationStatus() {
case .authorizedWhenInUse, .authorizedAlways:
showsUserLocation = true
centerViewOnUserLocation()
case .denied:
print("Auth Denied")
case .notDetermined:
locationManager?.requestWhenInUseAuthorization()
case .restricted:
print("Auth Restricted")
@unknown default:
print("Unkown default selected in \(#function)")
}
}
func centerViewOnUserLocation() {
guard let coordinate = locationManager?.location?.coordinate else { return }
let span = MKCoordinateSpan.init(latitudeDelta: 2, longitudeDelta: 2)
let region = MKCoordinateRegion.init(center: coordinate, span: span)
setRegion(region, animated: true)
}
}
我已经设置了plist隐私-使用中的位置使用情况描述消息,并且不确定是否还会使用。
答案 0 :(得分:0)
我知道了...我为mapView使用了自定义地标注释,该注释删除了默认注释。从技术上讲,蓝色当前位置标记是默认注释,因此也将其删除。
