I loo开发者_Python百科k many sample code for storing data into sqlite but it work .How I store this I am trying to add the the (newLocation.coordinate.latitude,newLocation.coordinate.longitude) into sqlite database . I find this (newLocation.coordinate.latitude,newLocation.coordinate.longitude) from here

 -(void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
    if (newLocation)
    {


        // make sure the old and new coordinates are different
        if ((oldLocation.coordinate.latitude != newLocation.coordinate.latitude) &&
            (oldLocation.coordinate.longitude != newLocation.coordinate.longitude))
        {    
            //I think Here will my sqlite query for storing the newLocation.coordinate.latitude and  newLocation.coordinate.longitude 
         //But I dont know how i store this location into the sqlite database.

         }
     }
}

How can i do .Can anyone help me out from this.


you can use this statement....

sqlite3_bind_double(stmt, 1, newLocation.coordinate.latitude);


using coredata would be much easier,other wise try storing into a plist.


Its pretty simple in my view, just made a function open sqlite db in it and then write this code

NSString *update = [[NSString alloc] initWithFormat:@"INSERT OR REPLACE INTO table (longitude, latitude) VALUES ('32.333, 74.6655');"];



char * errorMsg;

    if (sqlite3_exec (database, [update UTF8String], NULL, NULL, &errorMsg) != SQLITE_OK)
    {
        NSAssert1(0, @"Error updating tables: %s", errorMsg);   
    }

    NSLog(@"Location Inserted");
