Localization application in Chinese and English

I am creating an application in which I want to do localization in two languages:

1)English

2)Chinese

I have done the whole app with a simple localization method and it works fine for me.

But now problem is, if the user chooses his/her language t开发者_StackOverflow中文版hrough option of language selection in application as a Chinese or English it will convert the whole application as per language without quit or restart the application.

Any suggestions ???

It is possible and quite easy, have a look at How to force NSLocalizedString to use a specific language
