I am facing a problem. I am working on an app which is supported around 30 languages. I have tried google toolkit translate (https://translate.google.com/toolkit/ ) but it is not working properly. For example let assume in .string file I have 40 lines of codes. If I translate language using google toolkit then it converts just 4-7 lines sometimes 8-9 times and so on. Others all lines it skips. Please let me know how can we translate English language in multiple language (around 30) at a time. Please share Any tool name or site name. Thanks guys.
Here is a project which can convert your localization.strings file to any language using google translation api.
You just need to copy paste all the data of localization.string file into a txt file. and add that txt file in app bundle file and specify file name in Constants.h file. Also mention the google translator api key. You can also mail the translated file.
