Deleting an Object

Deleting a Single Object

You can call deleteObject to delete a single object. Sample code is as follows:

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.

Sample code:

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 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);
   }
}];
