IOS development based on Baidu map (7) -- convert Baidu coordinates to Google coordinates

Subject. Assume that Baidu coordinates are (x, y). In iOS-based Baidu map development (6), we regard (x, y) as Google coordinates and convert them, after conversion, the coordinates (x1, Y1) are obtained ). Then the calculation method of the real

IOS development based on Baidu map (6) -- Google coordinates to hundreds of coordinates

Real coordinates are not allowed in China, so each map service provider will encode the real longitude and latitude (or encrypt it ). For example, for the real longitude and latitude room (Lon, Lat) of People's Square, the latitude and longitude
