- 9. NSURLConnection Delegate Methods - connection:didReceiveResponse: - connection:didReceiveData: - connectionDidFinishLoading: - connection:didFailWithError: - connection:willCacheResponse:
- 10. NSOperation • Atomic Unitof Computation • Concurrently executed in NSOperationQueue • Encapsulates State • started, executing, finished • Cancelable • Completion Blocks
- 11. AFURLConnectionOperation • NSOperation Subclass •Implements NSURLConnection Delegate Methods • Supports Streaming Uploads / Downloads • Stores Request, Response, Data
