Protocol Buffers Output

To Objective-C(.h .m)

$ protoc --proto_path=src --objc_out=build/gen src/foo.proto src/bar/baz.proto

To Java(.java)

$ protoc --proto_path=src --java_out=build/gen src/foo.proto

--proto_path可以缩写为： －I

Install:

$ objectivec/DevTools/full_mac_build.sh

Building:

There are two ways to include the Runtime sources in your project:

Add objectivec/\*.h & objectivec/GPBProtocolBuffers.m to your project.

or

Add objectivec/\*.h & objectivec/\*.m except for
objectivec/GPBProtocolBuffers.m to your project.

If the target is using ARC, remember to turn off ARC (-fno-objc-arc) for the
.m files.

The files generated by protoc for the *.proto files (\*.pbobjc.h' and*.pbobjc.m`) are then also added to the target.
