Spatialite

Build Status Carthage Compatible License

Spatialite is a plugin for SQLite that allows for geo-spatial queries

Usage

  • Include spatialite and sqlite header
#import <spatialite/spatialite.h>
#import <sqlite3/sqlite3.h>
  • Initialize spatialite where ''mySQLite3Connection'' is your handle to a valid database instance
int sqliteInitStatus = sqlite3_initialize();
assert(sqliteInitStatus==SQLITE_OK);
        
int sqliteInitOSStatus = sqlite3_os_init();
assert(sqliteInitOSStatus==SQLITE_OK);
        
sqlite3_enable_load_extension(mySQLite3Connection, 1);
        
spatialite_initialize();

_spatialiteConn = spatialite_alloc_connection();
assert(_spatialiteConn);
spatialite_init_ex(mySQLite3Connection, _spatialiteConn, 1);```

After the above you can call SQLite with queries containing spatialite functions

Notes

If you use the sqlite3 built provided by iOS/Mac ensure this version supports loading extension (Alternatively build sqlite3 with extension support)
