持久HTTPS连接Objective-C iOS可可

Question

What's the best way to make persistent HTTPS connections in Objective-C with Cocoa Framework for iPhone with NSURLSession? I've read somewhere else that persistent connections are standard since HTTP 1.1. Some code example would be very appreciated. I need to achieve a simple data retrieval task (json encoded string)

best regards stefan

Answer 1

Follow this link http://www.objc.io/issue-5/from-nsurlconnection-to-nsurlsession.html to find out, what "no persistent" means to understand "persistent".

I haven't used NSURLConnection or NSURLSession myself, but persistent is not a special setting. It means, that the same settings-data is used for connection/session.

Answer 2

Nothing about NSURLSession...

But I've found a tutorial here http://www.raywenderlich.com/51127/nsurlsession-tutorial .
