Read/Write USB flash drive of exFAT format

Hello, I'm building iOS app to read/write files from MFI certified USB flash drive. Now the app can launch and detect the accessory with the correct protocol strings.

From the External Accessory framework documentation, the data needs to read/write with the NSInputStream & NSOutStream interfaces.

Would you give advices on how to parse the stream data? Am I doing it wrong? Or are there other easy methods to achieve this?

Thanks!
