Modifications to support of multiple localized resources
Use these files in your app. Make a directory called en.lproj (and for each locale you wish to use). Use CPLocalizedString() in your code wherever you want a localized string.
Generating String Files
OS X Only
==========
cd My\ App
genstrings -o en.lproj -s CPLocalizedString *.j
==========
(Edit strings file in en.lproj/)
==========
cd en.lproj
plutil -convert xml1 Localizable.strings -o Localizable.xstrings
==========
Rinse and repeat for as many localized strings files as you wish, making sure you add the appropriate key in the Info.plist (CPBundleLocalizedResourceKeys) in your application (see sample in this gist).
Helpful hint: You can use the comments argument in your use of CPLocalizedStrin() as a fall back:
CPLocalizedString("doneButtonLabel", " Done ");
You can create localized cib files as needed in the language specific *.lproj folders and load them with the CPBundle category method:
+ (CPCib)loadLocalizedCibNamed:(CPString)aName
owner:(id)anOwner
loadDelegate:(id)aDelegate
See the example in this gist called "MyController.j".
