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";
NSString *SK = @"*** Provide your Secret Key ***";
NSString *AK = @"*** Provide your Access Key ***";
    
// 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.

Sample code:

static OBSClient *client;
NSString *endPoint = @"your-endpoint";
NSString *SK = @"*** Provide your Secret Key ***";
NSString *AK = @"*** Provide your Access Key ***";
    
// 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);
   }
}];
