xcode - iOS 5 JSON Parsing Results in Cocoa Error 3840 -



xcode - iOS 5 JSON Parsing Results in Cocoa Error 3840 -

i'm having hard time parsing below json string on ios 5.

{"states": [{"name": "arizona","cities": [{"name": "phoenix"}]},{"name": "california","cities": [{"name": "orange county"},{"name": "riverside"},{"name": "san diego"},{"name": "san francisco"}]},{"name": "nevada","cities": [{"name": "las vegas"}]}]}

and here's code:

- (void) parsejson { nserror *jsonerror = nil; nsdata *jsondata = [nsdata datawithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"locations-json" oftype:@"rtf"]]; if (jsondata) { nsdictionary *jsonobjects = [nsjsonserialization jsonobjectwithdata:jsondata options:nsjsonreadingmutablecontainers error:&jsonerror]; if (jsonerror) { nslog(@"json error: %@", [jsonerror localizeddescription]); return; } nslog(@"%@", jsonobjects); } }

i maintain getting error:

json error: operation couldn’t completed. (cocoa error 3840.)

i'd appreciate help on because , incapable of fixing this.

one thing strikes me wrong this:

[[nsbundle mainbundle] pathforresource:@"locations-json" oftype:@"rtf"]

your info rtf file?? should txt file (or other sort of plain text file). rtf files contain text formatting data, this:

{\rtf1\ansi\ansicpg1252\cocoartf1138\cocoasubrtf470 {\fonttbl\f0\fswiss\fcharset0 helvetica;} {\colortbl;\red255\green255\blue255;} \margl1440\margr1440\vieww10800\viewh8400\viewkind0 \pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\pardirnatural \f0\fs24 \cf0 \{"states": [\{"name": "arizona","cities": [\{"name": "phoenix"\}]\},\{"name": "california","cities": [\{"name": "orange county"\},\{"name": "riverside"\},\{"name": "san diego"\},\{"name": "san francisco"\}]\},\{"name": "nevada","cities": [\{"name": "las vegas"\}]\}]\}}

when read that in info , seek parse json, 3840 error you're seeing. error's description says:

the info couldn’t read because has been corrupted. (no string key value in object around character 2.)

so looks me don't have json. have rtf data.
