Ich versuche, JSON-Antwort von einem Web-Service API zu bekommen. Ich möchte Produktdaten aus dem JSON extrahieren. Ich möchte dies auch mit AFNetworking implementieren, und ich versuche auch, Antwort mit NSURLSession zu bekommen und es funktioniert vollständig.AFNetworking, NSURLSession und JSON Antwort (Ronak Sankhala)

// and also download and check JSON demo : https://drive.google.com/open?id=0B0rS2ZVDMVRiSmJJb1BuQklJSzA[Click to show JSON demo Hear][1]
//add custom table view cell with custom table cell and add label to display information. i used pod to setup AFNetworking.
und auch herunterladen und überprüfen Demo JSON: https://drive.google.com/open?id=0B0rS2ZVDMVRiSmJJb1BuQklJSzAClick to show JSON demo Hear
Kann jemand einen Weg vorschlagen this.me, wie die Dinge getan werden zu tun.
