Recipe: Automatic Version Number, Build Number & Build Date Handling | MacIndie

I found this helpful “recipe” for setting up automatic build versioning in Xcode…

Dealing with build and version numbers in applications whether for Desktop MacOSX or iPhone applications always seems like a bit of a black art, here’s the short version of how to set up a consistent and maintainable system for dealing with version numbers in Xcode.

I did a couple things differently – mainly I just didn’t set up the “Versioning System” setting (let me know if you know of problems w/ doing this):

  • Add a “Versioning System” item, and set its value to “apple-generic”

I didn’t want to have to run agvtool next-version whenever I needed to update my Bundle version. I’ve used that on other projects and it’s just kinda a pain to have to run a command line command to update it. Too easy to forget, etc.

I ran it w/o that setting and logged out the settings when the app runs like this:


-(void)viewWillAppear:(BOOL)animated
{
   [super viewWillAppear:animated];

   NSString *appVersionNumber = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
   NSString *buildNumber = [[[NSBundle mainBundle] infoDictionary] valueForKey:@"CFBuildNumber"];
   NSString *buildDateString = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBuildDate"];

   NSLog(@"%@ %@ %@", appVersionNumber, buildNumber, buildDateString);
}

The output looked like this:
