Adding strings localization files from a server

Question

We are building an application with dynamic data that we wish to localize. We know how to localize strings in iOS and Android but in this case the data will be downloaded dynamically from the server so we will need to download the localization files dynamically.

Usually we store the strings files inside language folders. how can we do that when the file is coming from the server?

Answer 1

how can we do that when the file is coming from the server?

You can't because the app bundle is not writable on iOS devices.

There is, however, NSLocalizedStringFromTableInBundle(), which lets you specify a different bundle from which you can load the .strings file. I haven't tried but I suppose this bundle can also reside in your app's Documents or Library folder.

Answer 2

Yes, it's possible, but not using standard means. Check this github repository for simple and elegant solution.

It uses .json file which contains localization info and may be downloaded from server. All controllers need to subscribe to notifications sent by localization class and implement a method responsible for (re-)setting all texts in view.
