Deleting an Object
Deleting a Single Object
You can call deleteObject to delete a single object. Sample code is as follows:
static OBSClient *client; NSString *endPoint = @"your-endpoint"; // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running 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"); 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 an object. OBSDeleteObjectRequest *request = [[OBSDeleteObjectRequest alloc] initWithBucketName:@"bucketname" objectKey:@"objectname"]; [client deleteObject:request completionHandler:^(OBSDeleteObjectResponse *response, NSError *error) { NSLog(@"%@",response); }];
Deleting Objects in a Batch
You can call deleteObjects to delete multiple objects in a batch.
A maximum of 1000 objects can be deleted each time. Two response modes are supported: verbose (detailed) and quiet (brief).
- In verbose mode (default mode), the returned response includes the deletion result of each requested object.
- In quiet mode, the returned response includes only results of objects failed to be deleted.

static OBSClient *client; NSString *endPoint = @"your-endpoint"; // Hard-coded or plaintext AK/SK are risky.

OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider]; // Initialize an instance of OBSClient. client = [[OBSClient alloc] initWithConfiguration:conf]; // Delete objects in a batch. OBSDeleteObjectsRequest *deleteRequest = [[OBSDeleteObjectsRequest alloc] initWithBucketName:@"bucketname"]; // List of objects to be deleted OBSObjectToDelete *object1 = [[OBSObjectToDelete alloc] initWithObjectKey:@"objectname1"]; OBSObjectToDelete *object2 = [[OBSObjectToDelete alloc] initWithObjectKey:@"objectname2"]; deleteRequest.objectList = @[object1,object2]; [client deleteObjects:deleteRequest completionHandler:^(OBSDeleteObjectsResponse *response, NSError *error) { for(int i=0;i<response.deletedList.count;i++){ NSLog(@"%@\n",response.deletedList[i].key); } }];
