Request Permission for Camera and Library in iOS 10 - Info plist

Question

I have implemented a WKWebView in an app  there s a file input in the shown web page where it should import an image from photos  Whenever i press on that input and select either  Take Photo  or  Photo Library  the app suddenly crash  which I believe is because the app is missing the permission to either take a photo or import from library   How do I push a permission request when the user select one of the mentioned methods  Take Photo or Photo Library    I use Swift 3 0 with WKWebView

You can also request for access programmatically, which I prefer because in most cases you need to know if you took the access or not.

Swift 4 update:

    //Camera
    AVCaptureDevice.requestAccess(for: AVMediaType.video) { response in
        if response {
            //access granted
        } else {

        }
    }

    //Photos
    let photos = PHPhotoLibrary.authorizationStatus()
    if photos == .notDetermined {
        PHPhotoLibrary.requestAuthorization({status in
            if status == .authorized{
                ...
            } else {}
        })
    }

You do not share code so I cannot be sure if this would be useful for you, but general speaking use it as a best practice.

I wrote an extension that takes into account all possible cases    If access is allowed  then the code onAccessHasBeenGranted will be run  If access is not determined  then requestAuthorization     will be called  If the user has denied your app photo library access  then the user will be shown a window offering to go to settings and allow access  In this window  the  Cancel  and  Settings  buttons will be available to him  When he presses the  settings  button  your application settings will open    Usage example   PHPhotoLibrary execute controller  self  onAccessHasBeenGranted           access granted          Extension code   import Photos import UIKit  public extension PHPhotoLibrary       static func execute controller  UIViewController                         onAccessHasBeenGranted   escaping    - gt  Void                         onAccessHasBeenDenied      - gt  Void     nil           let onDeniedOrRestricted   onAccessHasBeenDenied               let alert   UIAlertController              title   We were unable to load your album groups  Sorry                message   You can enable access in Privacy Settings               preferredStyle   alert           alert addAction UIAlertAction title   Cancel   style   cancel  handler  nil            alert addAction UIAlertAction title   Settings   style   default  handler      in             if let settingsURL   URL string  UIApplication openSettingsURLString                   UIApplication shared open settingsURL                                      controller present alert  animated  true                 let status   PHPhotoLibrary authorizationStatus         switch status         case  notDetermined           onNotDetermined onDeniedOrRestricted  onAccessHasBeenGranted        case  denied   restricted           onDeniedOrRestricted         case  authorized           onAccessHasBeenGranted          unknown default           fatalError  PHPhotoLibrary  execute -   Unknown case                      private func onNotDetermined   onDeniedOrRestricted   escaping    - gt Void     onAuthorized   escaping    - gt Void        PHPhotoLibrary requestAuthorization   status in       switch status         case  notDetermined           onNotDetermined onDeniedOrRestricted  onAuthorized        case  denied   restricted           onDeniedOrRestricted         case  authorized           onAuthorized          unknown default           fatalError  PHPhotoLibrary  execute -   Unknown case

Use the plist settings mentioned above and the appropriate accessor  AVCaptureDevice or PHPhotoLibrary   but also alert them and send them to settings if you really need this  like so   Swift 4 0 and 4 1  func proceedWithCameraAccess identifier  String          handler in  requestAccess is needed to process user s answer to our request     AVCaptureDevice requestAccess for   video    success in       if success      if request is granted  success is true          DispatchQueue main async             self performSegue withIdentifier  identifier  sender  nil                    else      if request is denied  success is false             Create Alert         let alert   UIAlertController title   Camera   message   Camera access is absolutely necessary to use this app   preferredStyle   alert              Add  OK  Button to alert  pressing it will bring you to the settings app         alert addAction UIAlertAction title   OK   style   default  handler    action in           UIApplication shared open URL string  UIApplicationOpenSettingsURLString                           Show the alert with animation         self present alert  animated  true
