Shazron Abdullah commented on CB-6495:
--------------------------------------

Note for devs:
https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVAudioSession_ClassReference/Reference/Reference.html
see section "Audio Session Categories"

Probably only use a subset of these. Don't forget to update the docs.

> Media plugin : Need way to set session category for iOS

>             Project: Apache Cordova
>          Issue Type: Improvement
>          Components: Plugin Media
>         Environment: iOS, all
>            Reporter: Paul Kane

> I need a way to play a sound effect (the occasional "beep") in my Cordova app 
> without it shutting down any other Audio Sessions. Currently any sound from 
> my app will cancel iTunes/Spotify/etc background music.
> Apple has a bunch of "Audio Session" categories which determine how an app's 
> audio will mix with other audio streams. The documentation is here : 
> https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVAudioSession_ClassReference/Reference/Reference.html
> Anyway, the only 2 audio session categories mentioned in the Media plugin are 
> hard-wired in there and not configurable. It should probably be more of an 
> option, the way that playAudioWhenScreenIsLocked and numberOfLoops are 
> options. The category I needed was AVAudioSessionCategoryAmbient. For now 
> I've simply hard-wired it in for my project, but I'm going to need to patch 
> the plugin after every plugin upgrade, etc.
> Also worth noting, the setCategory function should probably be called before 
> the prepareToPlay function (it's not, currently). Without doing that, setting 
> the category wasn't having any effect for me. Found the solution here : 
> http://stackoverflow.com/questions/10377959/on-ipad-why-does-avaudiosessioncategoryambient-stop-the-music-playing-in-ipod
> I'm not an iOS programmer, and Objective-C and github both confuse the hell 
> out of me so you probably don't want me contributing my code to the plugin, 
> but hopefully these notes can be of help to someone better qualified.
