Deleting a Bucket

You can call deleteBucket to delete a bucket. Sample code is as follows:

static OBSClient *client;
NSString *endPoint = @"https://your-endpoint";
// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
char* ak_env = getenv("AccessKeyID");
char* sk_env = getenv("SecretAccessKey");
if (ak_env == NULL || sk_env == NULL) {
    NSLog(@"Error: AccessKeyID or SecretAccessKey environment variable not set");
    return;
}
NSString *AK = [NSString stringWithUTF8String:ak_env];
NSString *SK = [NSString stringWithUTF8String:sk_env];

// Initialize identity authentication.
OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];
    
//Initialize service configuration.
OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];
    
// Initialize an instance of OBSClient.
client = [[OBSClient alloc] initWithConfiguration:conf];
    
//Delete a bucket.
OBSDeleteBucketRequest *deleteRequest = [[OBSDeleteBucketRequest alloc] initWithBucketName:@"bucketname"];
[client deleteBucket:deleteRequest completionHandler:^(OBSDeleteBucketResponse *response, NSError *error) {
    NSLog(@"%@",response);
}];

• Only empty buckets (without objects and part fragments) can be deleted.
• Bucket deletion is a non-idempotence operation and an error will be reported if the to-be-deleted bucket does not exist.
