Creating an application for iphone


I’m trying to create an application for iphone based on OSM. This application is a Tourist guide from barcelona city, then I have to read the barcelona map and I have to interpret the points of interest (POI)

I found a lot of things in Java, but I have to programm with C++ because I read that C++ is working better than Java in iPhone.

I need any help, because now i’m lost. I began with travellingsalesman (a source code create in Java) but it isn’t compatible to programm with iPhone.

Any help will be welcome.

Best regards and thanks

Did you already have a look at to see whether there is any opensource app?

For more programs that might be programmed in C++, look at or look at other places in the OSM wiki.
