iOS 用戶位置權限

Question

我只是在創建一個需要獲取用戶位置的 iOS 應用程序。

我已將所需的鍵和值包含在 info.plist 中，如屏幕截圖所示：

但是在運行應用程序時，調試器中有一條消息：

2020-04-25 18:51:16.395466+0200 Jogua[23008:1151035] This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain both “NSLocationAlwaysAndWhenInUseUsageDescription” and “NSLocationWhenInUseUsageDescription” keys with string values explaining to the user how the app uses this data

我需要更改代碼中的其他任何內容嗎？

編輯

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    determineMyCurrentLocation()
}

func determineMyCurrentLocation() {
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestAlwaysAuthorization()

    if CLLocationManager.locationServicesEnabled() {
        locationManager.startUpdatingLocation()
    }
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let userLocation:CLLocation = locations[0] as CLLocation

    print("user latitude = \(userLocation.coordinate.latitude)")

     self.defaults.set(userLocation.coordinate.latitude, forKey: "mi_latitud")

    print("user longitude = \(userLocation.coordinate.longitude)")
    self.defaults.set(userLocation.coordinate.longitude, forKey: "mi_longitud")

}

func locationManager(_ manager: CLLocationManager, didFailWithError error: Error)
{
    print("Error \(error)")
}

Answer 1

正如您的調試器所說，您在info.plist中缺少一個條目。 這可能會產生誤導，因為控制台打印的名稱不是info.plist中的實際鍵名。

你補充說：

Privacy - Location Always Usage Description
Privacy - Location Usage Description
Privacy - Location Always and When In Use Usage Description

根據調試器，您需要的是：

Privacy - Location When In Use Usage Description
Privacy - Location Always and When In Use Usage Description

您需要在案例中添加的內容：

Privacy - Location When In Use Usage Description
