是否可以通过iDevice lightning端口访问数据?

I threw together a simple MicroSD to lightning adapter. Bought a female lightning to USB adapter to test it on my computer and windows recognizes the SD card. So will iOS even see the SD card? Or will iOS not see it? Because if iOS can at least see that there is something connected to the lightning port, I should be able to put together a simple program in xcode to at least read the contents. With more research and a more advanced program could hopefully be able to mount the card to the filesystem. Jailbroken iPhone 6S on 9.0.2 btw. Kind of skeptical though because if expandable storage was possible, various iOS/cydia developers would've already made it possible.I threw together a simple MicroSD to lightning
