I am actually developing an iOS / Android application containing a map showing some places (e.g. nearby places). I want to introduce the concept of an offline map, in other words, I want the user to download an offline map (with the same information as on the online map) when he was online.
The goal of this, not having maps of the whole world or continent, is just a city (for example, in New York) showing street names, and I can add annotations to it.
I really don't know where to start doing this.
If someone has an idea or have already tried a good solution, let me know.
Thanks in advance.
