Listing Buckets

You can call listBuckets to list buckets. 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];
    
// List buckets.
OBSListBucketsRequest *request = [OBSListBucketsRequest new];
    
[client listBuckets:request completionHandler:^(OBSListBucketsResponse *response, NSError *error) {
    for(OBSBucket *bucket in response.bucketsList){
        NSLog(@"bucketname=%@",bucket.name);
    }
}];

Obtained bucket names are listed in the lexicographical order.
