Common Methods of iOS JSONKit

During project interaction with the server, json Parsing is often required. If someone wants to parse JSON, JSONKit can be a good choice.

You can download JSONKit from gitHub at: JSONKit

Arr. conf

[{"preview_sub": "adornment_fly_1_100.png", "width": "300", "path": "adornment_fly_1.png", "name": "adornment_fly_1.png", "height": "300"}, {"preview_sub": "adornment_fly_2_100.png", "width": "300", "path": "adornment_fly_2.png", "name": "adornment_fly_2.png", "height": "300"}]
