In general, the LBS function is generally divided into two pieces, one is geo-positioning, is to obtain the current accuracy, latitude and location of the function, this part of the function is mainly used in Corelocation.frameworks. Part of this is to display the map information, enrich the map content, and so on, this part mainly uses Mapkit.frameworks. The test of these functions is best done on the real

ObjectiveRecently, due to work needs, need to extract some of the city latitude and longitude coordinates, a little search, found that Baidu map and the gold map provide relevant functions and examples. Then the rest of the work is relatively simple, save the coordinates, and then convert to WGS coordinates, so that the existing GPS data and map matching.Major pr
