If you are really interested in learning how to use SQLite to control your iOS App data, I recommend that you follow the tutorial below, it is a great guide:

IOS -5-SDK-Database-Insert-Update-Delete-with-SQLite-and-Objective-CC-How-To iphone-sdk -living-data-from-a-database-sqlite

Or see the example below of how to do an insert.

static sqlite3_stmt *insertStmt = nil;

if(insertStmt == nil) 
{
    insertSql = "INSERT INTO Loginchk (uname,password) VALUES(?,?)";
    if(sqlite3_prepare_v2(database, insertSql, -1, &insertStmt, NULL) != SQLITE_OK)
        NSAssert1(0, @"Error while creating insert statement. '%s'", sqlite3_errmsg(database));
}

sqlite3_bind_text(insertStmt, 1, [Gunameq UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(insertStmt, 2, [Gpassq UTF8String], -1, SQLITE_TRANSIENT);
if(SQLITE_DONE != sqlite3_step(insertStmt))
    NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
else
    NSLog("Inserted");

//Reset the add statement.
sqlite3_reset(insertStmt);
insertStmt = nil;

I hope it helps solve your problem.
