Xcode 6.0 :
It provides wonderful features for Internationalisation and Localisation. ("Localizing with Xcode 6" video). For quick usage I write some useful steps.
Step 1 :
click on project -> info -> scroll down -> localizations -> click on '+' and add your required language -> check as required -> Finish.
for xcode 6 : click on project -> change target to -> info > scroll down -> localizations -> click on '+' and add your required language -> check as required -> Finish.
Step 2 :
click on 'Supporting Files' -> right click -> New File -> select Resource on left-side list -> select 'Strings Files' -> next -> name it 'Localizable' -> create
Step 3 :
click on newly created file -> go to Utilities -> file inspector -> click on 'Localize..' -> check all language
Step 4 :
open Localizable.strings(English)
write
"help" = "I can't help you";
here "help" is a key
"I can't help you" is a value. You may change them as your wish.
open Localizable.strings(French) or the language you have set.
write accordingly and you can translate "I can't help you" to any
said language.
Step 5 :
// for test
NSString *str = NSLocalizedString(@"help", Nil);
NSLog(@"%@",str);
We have done it.
You may check.
Now, to test goto settings of device -> general -> International -> language -> select said language or the language you have chosen (There are limited languages).
Run your app.
Hope this will help you. It help me.
