    <p>Here is my problem :</p> <p>INPUT (from a certain website) :</p> <pre><code>{"error":[],"results":{"count":2,"data":[{"ART_ID":"656","ART_NAME":"Noir D\u00e9sir","ART_PICTURE":".....","NB_ALBUM":"15","NB_FAN":"90176","SMARTRADIO":"1","URL_REWRITING":"noir-desir"},{"ART_ID":"167225","ART_NAME":"LMFAO","ART_PICTURE":"....","NB_ALBUM":"17","NB_FAN":"122408","SMARTRADIO":"1","URL_REWRITING":"lmfao"}],"total":2}} </code></pre> <p>So, once I have that I'm using a few JSON classes :</p> <pre><code> NSError* jsonError = nil; //responseData contains my json feed NSDictionary* dict = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:&amp;jsonError]; NSLog(@"responseDictionary : \n%@\n--------\n", [dict description]); </code></pre> <p>In order to obtain the following :</p> <pre><code>{ error = ( ); results = { count = 2; data = ( { "ART_ID" = 656; "ART_NAME" = "Noir D\U00e9sir"; "ART_PICTURE" = 17b0a9c3defcf8c3eef943759606b3f4; "NB_ALBUM" = 15; "NB_FAN" = 90176; SMARTRADIO = 1; "URL_REWRITING" = "noir-desir"; }, { "ART_ID" = 167225; "ART_NAME" = LMFAO; "ART_PICTURE" = 72a09b9202da38afae077e80c7598212; "NB_ALBUM" = 17; "NB_FAN" = 122408; SMARTRADIO = 1; "URL_REWRITING" = lmfao; } ); total = 2; }; } </code></pre> <p>Here, I don't really have any problem... But now, I want to get the "data" field in this NSDictionary. So I just create a new one :</p> <pre><code>NSDictionary* resultField = [NSDictionary dictionaryWithDictionary:[dict objectForKey:@"results"]]; </code></pre> <p>Wich contains :</p> <pre><code>{ count = 2; data = ( { "ART_ID" = 656; "ART_NAME" = "Noir D\U00e9sir"; "ART_PICTURE" = 17b0a9c3defcf8c3eef943759606b3f4; "NB_ALBUM" = 15; "NB_FAN" = 90176; SMARTRADIO = 1; "URL_REWRITING" = "noir-desir"; }, { "ART_ID" = 167225; "ART_NAME" = LMFAO; "ART_PICTURE" = 72a09b9202da38afae077e80c7598212; "NB_ALBUM" = 17; "NB_FAN" = 122408; SMARTRADIO = 1; "URL_REWRITING" = lmfao; } ); total = 2; } </code></pre> <p>Now I want to get my "data" field, which now is a JSONArray (not a NSDictionary anymore...) :</p> <pre><code>NSArray* dataField = [[NSArray alloc] initWithArray:[dict objectForKey:@"data"]]; </code></pre> <p>But after that my dataField is empty... By that I mean this :</p> <pre><code>NSArray* dataField = [[NSArray alloc] initWithArray:[dict objectForKey:@"data"]]; if (!dataField || ![dataField isKindOfClass:[NSArray class]]) { NSLog(@"Pb parsing DATA field as NSArray..."); } NSLog(@"dataField : \n%@\n--------\n", [dataField description]); </code></pre> <p>Doesn't show me the error since it a correctly formatted NSArray, but prints me the following :</p> <pre><code>2012-02-02 14:08:52.315 myapp[5235:f803] dataField : ( ) </code></pre> <p>I now am lost, I really don't know what's happening... If you guys have any clue on this issue I'd be glad if you could help me !</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
