I can choose only Englist for localizing file in my Xcode 4.6. Is this a bug of Xcode 4.6? How to localize my file now? Special thanks! <img src="https://i.stack.imgur.com/rjkka.png" alt="enter image description here">

Before localize a file you have to add the language to the application, see image below: <img src="https://i.stack.imgur.com/sWs6O.png" alt="enter image description here">

You will have to add a localization to your project before you add a localization to a file in the project. See the image below: <img src="https://i.stack.imgur.com/gc7ku.png" alt="Adding localization to the project">
