How to change the preferred language of an iPhone app in iOS 4

Question

Changing the language of an iPhone app has been discussed many times, but I\'m stuck with this one: The provided solutions require the app to be restarted to make the change

Answer 1

You could write your own replacement for NSLocalizedString. In the header file, do something like

#undef NSLocalizedString
#define NSLocalizedString(key, comment) MyLocalizedStringFunction(key)

In your function, load the correct .lproj bundle using NSBundle, then call

[bundle localizedStringForKey:key value:nil table:nil];

on it to get the string you want.

I don't know if that's the best way: we had to use it because we wanted to support a language that didn't exist on the iPhone, so your problem may have a simpler solution.
