BOOL success = NO;

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code

CkoHttp *http = [[CkoHttp alloc] init];

// IMPORTANT: Make sure to change the URL, JSON text,
// and other data items to your own values.  The URL used
// in this example will not actually work.

CkoHttpResponse *resp = [[CkoHttpResponse alloc] init];
success = [http HttpStr: @"POST" url: @"https://json.penzance.org/request" bodyStr: jsonText charset: @"utf-8" contentType: @"application/json" response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;

// Display the JSON response.
NSLog(@"%@",resp.BodyStr);
