Demonstrates the Azure Delete Blob operation, which marks the specified blob for deletion. The blob is later deleted during garbage collection. Objective-C

// Azure Blob Service Example: Delete a particular blob in a specified container.
// See also: https://docs.microsoft.com/en-us/rest/api/storageservices/delete-blob

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
