1. In your Xcode project, create a Shell Script target called GenGitVersion.
2. Insert the following script in GenGitVersion’s Run Script phase, replacing the path to your git executable if need be:

   1 2 3

   git=/usr/local/git/bin/git version=`$git describe` echo "#define GIT_VERSION $version" > InfoPlist.h

3. Make GenGitVersion a dependency of your main target.
4. Add “InfoPlist.h” to your .gitignore file.
5. In your main target’s build settings:
1. Turn on Preprocess Info.plist File
2. Set Info.plist Preprocessor Prefix File to InfoPlist.h
6. In your app’s Info.plist set the Bundle versions string, short to GIT_VERSION

Now each time you build the main target, the version will be populated in the build’s Info.plist.

Examples

• If you tag a commit, the version returned by git describe is the tag name.
If the current commit isn’t tagged, you’ll get the most recent tag plus the number of additional commits and an abbreviated commit name. Here’s a 1.0b1 tag with 2 additional commits: 1.0b1-2-g3925f3b. This can be a good way to identify a private developer build.
• You can optionally add --dirty to git describe and the version will have -dirty appended if there are uncommitted changes to your working tree.
• git describe will fail if there are no tags in the current working tree.

I wrote the app because I don’t sync my iPad with the computer where we store all of our photos, but from time to time I like to grab a photo from the iPhoto library without having to sync.

I just submitted a new point release that fixes a few crashers and other bugs to the App Store, but go ahead and take a look at this one and let me know what you think.

Free Promo Codes!

Just for the readers of this site! If you’re interested in the app, send an email to promocodes at cimgf dot com with the subject line PhotoGrab Promo Codes. I will send an email containing a promo code to the first 50 I receive (since the Apple only issues 50 of them per version). Be patient with me as I will be responding manually as I receive the messages. It will be first come, first served. Otherwise, check it out in the App Store. Promo codes are only valid in the US App Store.

Update on Promo Codes

I have received a lot of email requests for promo codes and will be sending them to the first 50 by the end of the day today (06/23/2010). If you do not receive a code by the end of the day, you were not in the first batch. When the next release hits the App Store, I will have another 50 at my disposal and will send those to the next group. Thanks for your interest.
