ios development - How to do JSON parser? -

i'm new ios development. json file server.

i use nsdictionary objects. when debug, "name", "address" values.

but don't know how can "dish" elements "recommendation" object? in java development, know recommendation object, , "dish" array element. don't know happen in ios.

{       "results": [         {           "name": "ollise",           "address": "columbia university",           "geo": [             {               "coordinates": 40             },             {               "coordinates": 70             }           ],           "logo": "http:\/\/a0.twimg.com\/profile_images\/3159758591\/1548f0b16181c0ea890c71b3a55653f7_normal.jpeg",           "recommendation": [             {               "dish": "dish1"             },             {               "dish": "dish2"             }           ],          }       ]     } 

by way, in json, store url of image in "logo", cannot value when debugging. should use special format?

[restaurant setname:[dict objectforkey:@"name"]] // name [restaurant setlogo:[dict objectforkey:@"logo"]]   // can nothing! 

this way it

nsdictionary *response = [nsjsonserialization jsonobjectwithdata:yourdata options:nsjsonreadingmutableleaves error:nil]; nsdictionary *results = [[response objectforkey:@"results"] objectatindex:0]; nsstring *name = [response objectforkey:@"name"]; //... other objects nsarray *recommendation = [results objectforkey:@"recommendation"]; nsdictionary *recommendation1 = [recommendation objectatindex:0]; nsdictionary *recommendation2 = [recommendation objectatindex:1]; nsstring *dish = [recommendation1 objectforkey@"dish"]; nsstring *dish1 = [recommendation2 objectforkey@"dish"]; [restaurant setname:name]; nsstring *logo = [results objectforkey:@"logo"]; [restaurant setlogo:logo]; 

the results same dictionary 1 in json. treat braces ({}) nsdictionary , brackets ([]) nsarray. dish not array element, key in dictionary array element.
