Presenting camera permission dialog in iOS 8

Question

When my app tries to access the camera for the first time on iOS 8, the user is presented with a camera permission dialog, much like the microphone one for microphone access

Answer 1

For Swift 3, you can add this on your viewWillAppear method of your first view controller:

First import the AVFoundation framework

import AVFoundation

Then:

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

    let authorizationStatus = AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo)

    switch authorizationStatus {
    case .notDetermined:
        AVCaptureDevice.requestAccess(forMediaType: AVMediaTypeVideo) { granted in
            if granted {
                print("access granted")
            }
            else {
                print("access denied")
            }
        }
    case .authorized:
        print("Access authorized")
    case .denied, .restricted:
        print("restricted")

    }
}

Don't forget to add Privacy - Camera Usage Description key on your Info.plist
