[Camera] iOS8: Handle case where camera is not authorized?

Hi folks,

I'm working on iOS 8/iPhone 6 compatibility for my Cordova app, and one thing that's new in iOS 8 is the ability to enable/disable access to the camera on a per-app basis, for all regions. (Previously, I think this was only limited to certain regions such as China.)

As of iOS 7, there's a new API to test whether the app has access to capture the desired media type:

https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVCaptureDevice_Class/index.html#//apple_ref/occ/clm/AVCaptureDevice/authorizationStatusForMediaType:

[AVCaptureDevice authorizationStatusForMediaType:mediaType];

I didn't see any existing issues or discussion on this topic, so thought I'd bring it up here. Is detecting this scenario, and popping up a UIAlertView notifying the user (and offering a button to take them to the settings app), a reasonable addition to the camera plugin? I'm happy to put together a PR and file an issue if you think it's worth adding.

Thanks,
Dan

Thanks, Jesse. JIRA issue is created for this:

https://issues.apache.org/jira/browse/CB-7667

I have a code change locally that seems to work well for me. Shall I put it in a PR, or paste the code into the bug? It does require AVFoundation (to call the API below), and some localized strings to display in the alert dialog – though the latter could be handled by the JS caller if necessary.

Thanks Dan!

Please create an issue in JIRA [1]
You can assign component "iOS, Plugin Camera, Plugin Capture"
This looks pretty easy to fix, so I don't think you'll have to wait long.

Cheers,
  Jesse
