Objective-C

#import <CkoHttp.h>
#import <NSString.h>

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];

// Insert your AccessKey ID here:
http.AwsAccessKey = @"access-key";

// Insert your AccessKey Secret here:
http.AwsSecretKey = @"secret-key";

// To download from a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com 	"
// See Alibaba Object Storage Service Regions and Endpoints
http.AwsEndpoint = @"oss-us-east-1.aliyuncs.com";

NSString *bucketName = @"chilkat";
NSString *objectName = @"seahorse.jpg";
NSString *localFilePath = @"qa_output/seahorse.jpg";

success = [http S3_DownloadFile: bucketName objectName: objectName localFilePath: localFilePath];
if (success != YES) {
    NSLog(@"%@",http.LastErrorText);
}
else {
    NSLog(@"%@",@"File downloaded.");
