How to auto-increment Bundle Version in Xcode 4?

Question

I am trying to figure out how to have the Bundle version number increment automatically in my Xcode 4 project (for ad-hoc and release builds). I found some scripts online th

Answer 1

For anyone wanting to integrate version incrementing into a command line build script (perhaps for continuous integration), see the following commands:

    # cd into the project folder containing the plist
    cd /Users/waitea/iOS/E.ON/iOS/trunk/Eon

    # grab the version numbers
    major_version=$(grep -C 2 CFBundleVersion App-Info.plist | grep -o '[0-9]\+.[0-9]\+.[0-9]\+')
    major_version_min=$(echo $major_version | grep -o '[0-9]\+.[0-9]\+\.')
    minor_version=$(echo $major_version | grep -o '[0-9]\+$')

    # increment the minor version
    increment=`expr $minor_version + 1`
    incremented_whole_version="$major_version_min$increment"

    # replace the build number in the plist using perl
    /usr/bin/perl -p -i -e "s/$major_version/$incremented_whole_version/g" App-Info.plist

That will increment the rightmost number in a x.x.x style version number. Tweak the reg-ex's to alter for your convention.

Took me a while so I thought I'd share to give back to the community!

EDIT - I created a continuous integration system that'll do this for you
