Hi,
I guess you want to fit the context language to the device language:
you can add more than one languages to the array:
#PlistExtra: <key>CFBundleLocalizations</key><array><string>German</string><string>French</string><string>Italian</string></array>
I have made some tests:
iOS will automatically choose the correct language, if the array doesn't contain the device language, but "English", english will be chosen. If the array doesn't contain the device language and "English", the first entry of the array will be choosen.
