检查 iOS 14 上的用户位置权限状态

Question

所以我想检查我是否有权访问 iOS14 上的用户位置&我找到了这段代码，但 XCode(12) 对我大喊大叫：

'authorizationStatus()' was deprecated in iOS 14.0

这是代码：

func hasLocationPermission() -> Bool {
       var hasPermission = false
       if CLLocationManager.locationServicesEnabled() {
           switch CLLocationManager.authorizationStatus() { // <= 'authorizationStatus()' was deprecated in iOS 14.0
           case .notDetermined, .restricted, .denied:
               hasPermission = false
           case .authorizedAlways, .authorizedWhenInUse:
               hasPermission = true
           @unknown default:
               hasPermission = false
             }
       } else {
            hasPermission = false
       }
        return hasPermission
}

那么我应该用什么来代替呢？

Answer 1

iOS 14 及更早版本

func locationAuthorizationStatus() -> CLAuthorizationStatus {
    let locationManager = CLLocationManager()
    var locationAuthorizationStatus : CLAuthorizationStatus
    if #available(iOS 14.0, *) {
        locationAuthorizationStatus =  locationManager.authorizationStatus
    } else {
        // Fallback on earlier versions
        locationAuthorizationStatus = CLLocationManager.authorizationStatus()
    }
    return locationAuthorizationStatus
}

在 iOS 14 中，“authorizationStatus()”已弃用：

https://developer.apple.com/documentation/corelocation/cllocationmanager/1423523-authorizationstatus

您应该使用 locationManagerDidChangeAuthorization 代替：

func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {

        switch manager.authorizationStatus {
            case .authorizedAlways , .authorizedWhenInUse:
                break
            case .notDetermined , .denied , .restricted:
                break
            default:
                break
        }
        
        switch manager.accuracyAuthorization {
            case .fullAccuracy:
                break
            case .reducedAccuracy:
                break
            default:
                break
        }
}
