Protocol Buffers in xcode 6 Mac 10.9

Question

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.

Answer 1

you can find your the ProtocolBuffers.h in ProtocolBuffers-2.2.0-Source ▸ objectivec ▸ Classes.

In step2, first you create a workspace and add you current project to your workspace, and then add the ProtocolBuffers.xcodeproj to the workspace which is in the ProtocolBuffers-2.2.0-Source ▸ objectivec.

you can see here about how to add a existing project to the workspace, hence, your current project can't be opened when you add it.

and in xCode 6, there is no pch file, you can get your help here: Why isn't ProjectName-Prefix.pch created automatically in Xcode 6?
