Cocoa Framework Localization

NSLocalizedString and friends uses [NSBundle mainBundle] to load localized strings from localization tables (by default Localized.strings file). For Framework code, in runtime -mainBundle returns Cocoa application bundle what uses the framework, not the framework bundle itself. But I needed to store localized strings inside a Framework bundle and use them from Framework.
It turns out the solution is really simple — refer bundle by identifier:

[NSBundle bundleWithIdentifier:kZeebaBundleIdentifier]

…or by Objective-C Class what’s stored inside a bundle:

[NSBundle bundleForClass:[Zeeba class]]

So, if framework’s bundle identifier is com.amateurinmotion.Zeeba, the NSLocalizedString helper macro would be:

#define kZeebaBundleIdentifier @"com.amateurinmotion.Zeeba"

#define ZeebaLocalizedString(key, comment)                                                 \
 NSLocalizedStringFromTableInBundle((key)                                                  \
                                    nil,                                                   \
                                    [NSBundle bundleWithIdentifier:kZeebaBundleIdentifier],\
                                    (comment))

Usage:

ZeebaLocalizedString(@"ZeebaGreeting", @"Huluu zeeba")

To generate Localizable.strings from implementation files what uses ZeebaLocalizedString macro:

genstrings -s ZeebaLocalizedString *.m
