#import <CkoCsv.h>

// This example program loads a file (sample.csv)
// that contains this content:
// 
// year,color,country,food
// 2001,red,France,cheese
// 2005,blue,"United States",hamburger
// 2008,green,Italy,pasta
// 1998,orange,Japan,sushi
// 
// The first row contains the column names.
// This file is available at:
// http://www.chilkatsoft.com/testData/sample.csv

CkoCsv *csv = [[CkoCsv alloc] init];

// Prior to loading the CSV file, indicate that the 1st row
// should be treated as column names:
csv.HasColumnNames = YES;

// Load the CSV records from the file:
BOOL success;
success = [csv LoadFile: @"sample.csv"];
if (success != YES) {
    NSLog(@"%@",csv.LastErrorText);
    return;
}

// Display the contents of the 3rd column (i.e. the country names)
int row;
int n = [csv.NumRows intValue];
for (row = 0; row <= n - 1; row++) {
    NSLog(@"%@",[csv GetCell: [NSNumber numberWithInt: row] col: [NSNumber numberWithInt: 2]]);
