this nsdictionary :

{ "@mode" = walk; "@route" = "rue university"; distance = "17.513516908661757"; duration = 13000; endtime = "2011-04-29t12:08:59.395-04:00"; =     {     geometry = "{\"type\": \"point\", \"coordinates\": [-73.57120386807037,45.503820214186405]}";     lat = "45.503820214186405";     lon = "-73.57120386807037";     name = "rue university"; }; leggeometry =     {     length = 3;     points = "{mvtg`k``mod@me"; }; starttime = "2011-04-29t12:08:46.395-04:00"; steps =     {     walksteps =         (                     {             absolutedirection = northwest;             becomes = false;             distance = "17.513516908661757";             elevation = "";             lat = "45.503820214186405";             lon = "-73.57120386807037";             stayon = false;             streetname = "rue university";         },                     {             absolutedirection = north;             becomes = true;             distance = "0.0";             elevation = "";             lat = "45.50390573910769";             lon = "-73.57139257694809";             relativedirection = right;             stayon = false;             streetname = "street transit link";         }     ); }; =     {     geometry = "{\"type\": \"point\", \"coordinates\": [-73.571363,45.503971]}";     lat = "45.503971";     lon = "-73.571363";     name = "station mcgill";     stopid = 32; }; 

looks object @ index 0 nsdictionary.

nsdictionary *dict = [array objectatindex:0]; nsstring *route = [dict objectforkey:@"@route"];
