The language of the keyboard can't be chosen by the app, the user can set which keyboard-language to prefer, and you can't choose what it should say on the return-button.
You can set the UIReturnKeyType
, so that it will show something different than "return" (these will also be localized):
setReturnKeyType:(UIReturnKeyDefault|UIReturnKeyGo|UIReturnKeyGoogle|UIReturnKeyJoin|UIReturnKeyNext|UIReturnKeyRoute|UIReturnKeySearch|UIReturnKeySend|UIReturnKeyYahoo|UIReturnKeyDone|UIReturnKeyEmergencyCall)
@quixoto, I didn't see your answer until I had posted mine, sorry.
