I have been researching how to make a demo on Protocol Buffers in iOS I found this tutorial recommended by a lot of people:https://code.google.com/p/metasyntactic/wiki/ProtocolBuffers
I use 10.9 Mac version and xcode 6 with command-line tool installed.
I have followed this tutorial and downloaded protobuf-2.6.0 and get some problem in "Project Integration" from step 2 to step 6. I don't understand how to do it in step 2 and I can't find /Classes/ProtocolBuffers.h in step 3. Also in step 4 and 5. Can anyone help me explain cleary this tutorial.
