Preprocess strings file during Xcode build

I know there's a way to pr开发者_运维问答eprocess my info.plist file, but is there a similar way to process strings files inside my Settings.bundle?

My problem: I have an iPhone app and I want the the user to know about the currently installed version. I do this by displaying it in the apps settings. Now every time i change the bundle version in my info.plist i also have to change the version in the Root.strings in the Settings.bundle. I could run a script action that updates it, but it would be nice to use the preprocessor since I could do even more fun things with it.

Thanks!

The preprocessor XCode runs on all string-files is copystrings. It resides in /Developer/Library/Xcode/Plug-ins/CoreBuildTasks.xcplugin/Contents/Resources. It's a simple ruby script, but it dosen't support any preprocessing/macro-expansion.

You could of cause extend the script, but then you would be easier off with a different script running in a run script build phase, as you already suggested.

Make it so that your view asks the bundle and then directly queries the Info.plist file and extracts the CFBundleVersion (or the appropriate key you wish to extract) The version should never need to be stored in a .strings file. Next all you need to do is have a format string to prepare it for display. One useful thing if you care about localization is to instead have a localized string in your .strings labeled something like "%@<CFBundleVersion format string>" = "Version: %@"; Then you get a quick visual indicator if your localizers have done their jobs in all languages.

MyInfoView *infoView = /*...*/;
NSString *version = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];
infoView.versionLabel.text = [NSString stringWithFormat:NSLocalizedString(@"%@<CFBundleVersion format string>",nil), version];
