Is there a way to ask user for Camera access after they have already denied it on iOS?

Question

I am using this code, but unfortunately it doesn\'t work.

After a user has denied camera access, I want to ask them for permission to use the camera again the next t

Answer 1

For Swift 3.0

This will lead the user to settings for changing the permission.

func checkCameraAuthorise() -> Bool {
    let status = AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo)
    if status == .restricted || status == .denied {
        let dialog = ZAlertView(title: "", message: "Please allow access to the camera in the device's Settings -> Privacy -> Camera", isOkButtonLeft: false, okButtonText: "OK", cancelButtonText: "Cancel", okButtonHandler:
            { _ -> Void in UIApplication.shared.openURL(URL(string: UIApplicationOpenSettingsURLString)!)}, cancelButtonHandler: { alertView in alertView.dismissAlertView() })
        dialog.show()
        return false
    }
    return true
}
