No controls on iOS lock screen

[anilo]

I am using the CastVideos project provided by Google, which includes the casting SDK.

Then I copies the 3 files provided by this project, but it doesn't work.

Also, I have added some capabilities of the project to run in the background.

Here's a link to the full project. Please try it.

The only change I've done to the original Cast Video project provided by Google is enabled the background mode from the capabilities section of the two targets.

Let me know if you have any suggestions.
