ios - Url correct but the dictionary is null -


i have download data using json, url correct (tested on chrome) empty dictionary. did go wrong?

  nslog(@"'url %@", stringurl); //correct   nsurlrequest *request = [nsurlrequest requestwithurl:[nsurl urlwithstring:stringurl]];   nshttpurlresponse __autoreleasing *response = nil;   nserror __autoreleasing *error = nil;   nsdata *result = [nsurlconnection sendsynchronousrequest:request returningresponse:&response error:&error];   // result is:   /* <280d0a0d 0a0d0a0d 0a0d0a0d 0a0d0a7b 22636f6d 6d6f6e22 3a7b2261 636b223a       224f4b22 2c226661 756c7443 6f646522 3a6e756c 6c2c2266 61756c74 53747269       6e67223a 6e756c6c 7d2c2274 6f74616c 223a3138 362c2270 61676522 3a312c22        .......*/   nsstring *str = [[nsstring alloc] initwithdata:result encoding:nsutf8stringencoding];   nslog(@"  string %@", str);   //the string correct  sbjsonparser *parser = [[sbjsonparser alloc] init];  nslog (@"the parser %@", parser);  //the parser  <sbjsonparser: 0x8877400>  nsdictionary *object = [parser objectwithdata: result];   nslog(@" dictionary %@", object);// dictionary null

the result of string:

  nsstring *str = [[nsstring alloc] initwithdata:result encoding:nsutf8stringencoding];   nslog(@" string %@", str);    /* ({"common": {"ack":"ok",  "faultcode":null,   "faultstring":null},        "total":8,         "page":1,         "limit":15,          "products":[{"name":"banane solidal biological  - cartone/estero/2^           cat.",          "code":"52436",          "anabel":"264342000",          "haspezzature":true,          "pezzaturelist":            [{"weight":700.000,"unit":"gr","formatted":"700gr"}],               "disponible":true,              "promotionimage":null},          {"name":"kiwi  105-120 ii^ vas           500gr",           "code":"52094",           "anabel":"393261000",            "haspezzature":true,            "pezzaturelist":            [{"weight":500.000,"unit":"gr","formatted":"500gr"}],               "disponible":true,               "promotionimage":null},                ........                .........]});*/

i put formatting readable, in fact returned data on 1 line

there "(" , ")" @ starting , ending of json response when try cast in nsdictionary or nsarray, doesnt recognize , hence goes empty. parsed you'll need add this: 

str = [[str stringbyreplacingoccurrencesofstring:@"(" withstring:@""] stringbyreplacingoccurrencesofstring:@")" withstring:@""];

before 

sbjsonparser *parser = [[sbjsonparser alloc] init]; nslog (@"the parser %@", parser); //the parser  <sbjsonparser: 0x8877400> nsdictionary *object = [parser objectwithdata: result];  nslog(@" dictionary %@", object);// dictionary null

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
