Changing language on the fly, in running iOS, programmatically

Question

I\'ve been stackling and googling for hours. And I\'m kind of desperate now. I would like to change the language of my application inside the app not only with the default l

Answer 1

Generally, the language the user sees is determined by the locale setting, which is a system-wide setting. Only the user can change it, and when he does, SpringBoard and every running application on the device must restart. There is no way around this because all system apps and frameworks assume that the locale doesn't change once they start running. Changing the apps and frameworks to not require a relaunch would be very difficult for Apple to do.

I'm guessing that you either want to vary the language of your app's interface completely independently of the system locale setting, or you want to use the system locale setting by default but allow the user to override it for just your app.

You can get the current locale and examine its various values using +[NSLocale currentLocale]. To display your app's user interface in a language that is independent of the system locale, you'll need to avoid usage of NSLocalizedString() entirely, and use some sort of custom state of your own to determine which strings to display to the user and how to modify the interface to fit your app's language. It'll be up to you to keep your app's language state and modify its user interface appropriately.
