How to use Powergate API in IOS

[tangshuya]

The Powergate version I'm using is 0.6.8,I converted some .proto files to object-c format and generated .h .m files.
Import a file into IOS program, the program can run normally,However, if multiple files are imported into IOS program, errors will be reported when compiling. For example, errors will be reported when importing files generated by ffs.proto and wallet.proto at the same time. How to solve this problem?
Can I use Powergate API directly by importing .proto file in iOS program? Which file does the IOS program set to associate with the poswergate instance?
thanks.
