Please Allow Camera Access shows in camera view even if accepted allowing access.

For what it is worth, I'm using the version where you haven't created DKCamera, so I don't know if new versions fix this, but this is a problem I've run into. The only way to get rid of it is to close the app, reopen and then try again.

If I decide not to accept allowing access, I see the prompt again, it takes me to settings, but when I change the settings, then go back to app, the prompt is still there.

Does DKCamera fix this?

Edit: I just checked and DKCamera doesn't seem to have this fixed.

Upon further examination, I think this is because if not authorized, a overlay is placed on the camera view. The current way doesn't care if the user allows for camera use because the overlay was already set. I think a better way is to only allow one to see the Camera view if they have authorized it. Otherwise, don't let them get there.

I think the following way is a good way to handle it.

The following code should suffice:

let authorizationState = AVCaptureDevice.authorizationStatusForMediaType(AVMediaTypeVideo)

switch authorizationState {
case .Authorized:
    self.presentViewController(pickerController, animated: true, completion: nil)
case .Denied:
    let appName =  NSBundle.mainBundle().infoDictionary?["CFBundleName"] as! String
    let alertTitle = "\"\(appName)\" Would Like to Access the Camera"

    let alert = UIAlertController(title: alertTitle, message: nil, preferredStyle: .Alert)

    let dontAllowAction = UIAlertAction(title: "Don't Allow", style: .Default, handler: nil)
    let goToSettingsAction = UIAlertAction(title: "Go To Settings", style: .Default, handler: { alert in
        UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)
    })

    alert.addAction(goToSettingsAction)
    alert.addAction(dontAllowAction)

    self.presentViewController(alert, animated: true, completion: nil)
case .NotDetermined:
    AVCaptureDevice.requestAccessForMediaType(AVMediaTypeVideo, completionHandler: { granted in
        if granted {
            dispatch_async(dispatch_get_main_queue()) {
                self.presentViewController(pickerController, animated: true, completion: nil)
            }
        }
    })
case .Restricted:
    let alert = UIAlertController(title: "Feature is Restricted on this Device", message: nil, preferredStyle: .Alert)

    let dismissAction = UIAlertAction(title: "OK", style: .Cancel, handler: nil)

    alert.addAction(dismissAction)

    self.presentViewController(alert, animated: true, completion: nil)
}

Of course, you changed your solution to use DKCamera, so you'll need to refine it a bit to be able to inject this somewhere, but the logic holds.

I will release the 3.0.0 with Photos framework. develop. I believe this will improve the issue.
