Questions tagged [nsurlconnection]

An NSURLConnection is the Apple Foundation Framework class that provides support to perform the loading of a URL request. It is deprecated and should be replaced by NSURLSession.

An NSURLConnection object provides support to perform the loading of a URL request. The interface for NSURLConnection is sparse, providing only the controls to start and cancel asynchronous loads of a URL request.

It is deprecated in iOS 9.0 and OS X 10.11 and should be replaced by NSURLSession.
