At all, or in particular via USB?
That would be with a USB cable- I set up the same model a few weeks ago and I use an iPhone 6; the homeowner, his ex-wife & their kids have iPhones, too. I bought a Yamaha MusicCast WXC-50 and control it with my phone after that project and it works great- I recommend looking into it as a good solution to a lot of problems we deal with. More inputs and outputs than Sonos, too.
