copied!<p>Thanks Dimitris. So changing the language at runtime is not that simple.</p> <p>I found a solution which works in my case:</p> <p>When the user changes the language I use the solution described by Mauro Delrio in <a href="https://stackoverflow.com/questions/1669645/how-to-force-nslocalizedstring-to-use-a-specific-language">"How to force NSLocalizedString to use a specific language"</a>. In monotouch:</p> <pre><code> string newLanguage = "nl"; myBundle = NSBundle.FromPath(NSBundle.MainBundle.PathForResource(newLanguage, "lproj")); </code></pre> <p>All strings will now be loaded in the selected language with myBundle.LocalizedString(...). Of course, everything which was already printed on a view is not yet translated. But I found an easy way to reset all views. In my app I use a MainTabController which looks like this:</p> <pre><code>public class MainTabBarController : UITabBarController { public override void ViewDidLoad() { Reset(); SelectedIndex = 2; } public void Reset() { ViewControllers = new UIViewController[] { new ViewControllerTab1(), new ViewControllerTab2(), new ViewControllerTab3(), new ViewControllerTab4(), new ViewControllerTab5() }; } } </code></pre> <p>So all I have to do is call Reset like:</p> <pre><code>((AppDelegate)UIApplication.SharedApplication.Delegate).MainTabBarController.Reset(); </code></pre> <p>All current views are disposed and re-created in the correct language. Seems like a trick, but it is perfectly legal and documented, see <a href="http://developer.apple.com/library/ios/documentation/uikit/reference/UITabBarController_Class/Reference/Reference.html#//apple_ref/occ/instp/UITabBarController/viewControllers" rel="nofollow noreferrer">Apple documentation for MainTabBarController viewControllers property</a>. It even activates the same tab index as the one which was active, so for the user it seems that nothing but the language is changed.</p> <p>Of course, any unsaved data in all views is lost, so if this is a problem, you have to find a way to save this before resetting. </p>
