Change language used in copy/paste menu to something other than English

Question

I have set "Localization native development region" to "France" in my Info.plist. Nevertheless, the copy/paste menu on a UITextField is still in English. I do not understand why, and I guess the app is still in English.

What setting do I need to change to make this menu use French?

Answer 1

Found this was set by 'Localization native development region' in 'Info.plist'

You could find it by clicking the target and select 'Info' tab

Answer 2

I have a solution for this problem. when you run app by Developer, It will show english. But When apple review it, It will change follow language device.

I can set language Developer in Info.plist
