NSString *bucketName = @"chilkat.ocean";
NSString *objectName = @"seahorse.jpg";
http.AwsRegion = @"us-west-2";
http.AwsEndpoint = @"s3-us-west-2.amazonaws.com";

int retval = [[http S3_FileExists: bucketName objectName: objectName] intValue];
if (retval < 0) {
    NSLog(@"%@",@"Failed to check for the S3 object existence");
    NSLog(@"%@",http.LastErrorText);
    return;
}

if (retval == 0) {
