How to force NSLocalizedString to use a specific language

How to Make NSLocalizedString Speak Your Language 🌍✨

Are you tired of your app speaking in the wrong language? 😫 Do you want to force NSLocalizedString to use a specific language, regardless of the user's device settings? 🌟 Well, you're in luck because we've got the solution for you! 🙌

The Problem 💔

On iPhone, NSLocalizedString is designed to return strings in the language set on the user's device. While this is helpful for localization purposes, it may not always align with your app's language requirements. 😔

The Solution 🚀

Fortunately, there's a way to override the default behavior of NSLocalizedString and make it use a specific language of your choice. 🎉 So, how can we achieve this? Let's dive in! 💪

Step 1: Create a Language Bundle 📦

The first thing you need to do is create a language bundle for the specific language you want to use. A language bundle is a separate directory that contains the translated strings for your app.

To create a language bundle, follow these steps:

1. In Xcode, right-click on your project, and select "New Group" from the contextual menu.

2. Name the new group something meaningful like "Languages".

3. Right-click on the "Languages" group, and select "New Group" once again. Name this group after the language you want to use (e.g., "French.lproj" for French).

4. Now, navigate to the Finder, find the newly created language group, and drag your localized strings files (e.g., "Localizable.strings") into it.

Step 2: Override the Language at Runtime 🏃‍♂️

To force NSLocalizedString to use the desired language at runtime, you'll need to modify the main() function in your app's main.m file.

1. Locate the main.m file in the "Supporting Files" group of your Xcode project.

2. Within the main() function, add the following code before the return statement:

   // Set the desired language [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"YourDesiredLanguage", nil] forKey:@"AppleLanguages"];

   Replace "YourDesiredLanguage" with the language identifier of your choice (e.g., "fr" for French).

3. Build and run your app. Voilà! 🎉

Caveats and Considerations ⚠️

While the above solution works in most cases, there are a few important points to keep in mind:

• Modifying the language at runtime may cause unexpected behavior with dynamic UI elements or third-party libraries that rely on the device's language.

• Manually overriding the language goes against Apple's recommended practices for localization. So, use this technique judiciously and consider alternative methods if possible.
