How to localise a string inside the iOS info.plist file?

问题

As you might know the iOS 8 requires NSLocationWhenInUseUsageDescription key for using user\'s location. I have added this key and some general information into my info plist.

How can I use translation string inside the plist file ?

-- Update --

I already have a Localizable string. I\'m just wondering that can I use something like NSLocalizedString(MYSTRING,nil) inside the plist string. I know that I can create multiple file of info.plist for localisation but I was wondering there might be an easier way.

回答1:

You should use InfoPlist.strings file to localize values of Info.plist. To do this, go to File->New->File, choose Strings File under Resource tab of iOS, name it InfoPlist, and create. Open and insert the Info.plist values you want to localize like:

NSLocationWhenInUseUsageDescription = "Description of this";

Now you can localize InfoPlist.strings file with translations. Good Luck!

EDIT:

select the localization options, or enable localization if needed,

you should be able to see the file also on the left side editor.

EDIT:

Here is the official documentation for Info.plist keys localization.

All the above did not work for me (XCode 7.3) so I read Apple reference on how to do, and it is much simpler than described above. According to Apple:

Localized values are not stored in the Info.plist file itself. Instead, you store the values for a particular localization in a strings file with the name InfoPlist.strings. You place this file in the same language-specific project directory that you use to store other resources for the same localization.

Accordingly, I created a string file named InfoPlist.strings and placed it in the xx.lproj folder of the "xx" language (and added it to the project using File->Add Files to ...). That's it. No need for the key "Localized resources can be mixed" = YES, and no need for InfoPlist.strings in base.lproj or en.lproj.

The application uses the Info.plist key-value as the default value if it can not find a key in the language specific file. Thus, I put my English value in the Info.plist file and the translated one in the language specific file, tested and everything works.

In particular, there is no need to localize the InfoPlist.strings (which creates a version of the file in the base.lproj, en.lroj, and xx.lproj), and in my case going that way did not work.

If something is not working make sure you added:

"Localized resources can be mixed" = YES

into the info.plist. In my case the InfoPlist.strings files were just ignored.

回答4:

I would highly recommend reading Apple's guides, and viewing the WWDC resources listed here: Internationalization and Localization Topics

To specifically answer your question, when you add a new language to your project

, you get an opportunity to choose what InfoPlist files to include (if you have multiple targets, you'll have multiple Info plist files). All you need to do to get the following screen is hit the + under Localizations and choose a new language to add support for.

Once you've added, it will create the necessary string files in the appropriate lproj directories for the given language.

--EDIT--

Just to be clear, iOS will swap out the string for your Plist file based upon the user's currently selected language using the plist entry's key as the key in the localized strings file.

Tips

1. Remember that the iOS Simulator exploits by default your system language. Please change the language (and region) in the iOS Simulator Setting too in order to test your translations.

2. The localisation string (see Apple docs here) should be

   NSLocationWhenInUseUsageDescription = "Description of this";
   

   and not (with quote "...")

   "NSLocationWhenInUseUsageDescription" = "Description of this";

Step by step localize Info.plist:

1. Find in the x-code the folder Resources (is placed in root)
2. Select the folder Resources
3. Then press the main menu File->New->File...
4. Select in section "Resource" Strings File and press Next
5. Then in Save As field write InfoPlist ONLY ("I" capital and "P" capital)
6. Then press Create
7. Then select the file InfoPlist.strings that created in Resources folder and press in the right menu the button "Localize"
8. Then you Select the Project from the Project Navigator and select the The project from project list
9. In the info tab at the bottom you can as many as language you want (There is in section Localizations)
10. The language you can see in Resources Folder
11. To localize the values ("key") from info.plist file you can open with a text editor and get all the keys you want to localize
12. You write any key as the example in any InfoPlist.strings like the above example

"NSLocationAlwaysAndWhenInUseUsageDescription"="blabla";

"NSLocationAlwaysUsageDescription"="blabla2";

That's all work and you have localize your info.plist file!

回答7:

For anyone experiencing the problem of the info.plist not being included when trying to add localizations, like in Xcode 9.

You need make the info.plist localiazble by going into it and clicking on the localize button in the file inspector, as shown below.

The info.plist will then be included in the file resources for when you go to add new Localizations.

回答8:

As RGML say, you can create an InfoPlist.strings, localize it then add your key and the value like this: "NSLocationWhenInUseUsageDescription" = "Help To locate me!";

It will add the key to your info.plist for the specified language.

回答9:

In my case everything was set up correctly but still the InfoPlist.strings file was not found.

The only thing that really worked was, to remove and add the InfoPlist.strings files again to the project.

回答10:

In my case the localization not worked cause of '-' symbol in the name. Example: "aero-Info.plist" And localized files: "aero-InfoPlist.strings" and "aeroInfoPlist.strings" did not work.
