    <p>I am trying to build a dictionary which has as dictionary within it (eventually I hope to convert to a JSON). The problem is I am having problems building it.</p> <p>So far I have this, what it should do is build a small dictionary with keys and add it to a larger dictionary, reset and then load the small dict and then add it to the large one.</p> <pre><code>NSMutableDictionary *nestedList = [[NSMutableDictionary alloc]init]; NSMutableDictionary *nestedSections = [[NSMutableDictionary alloc] init]; [nestedList addEntriesFromDictionary:[NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:46], @"menuHeight", @"editText", @"menuMethod", [NSNumber numberWithInt:1], @"menuOption", nil]]; [nestedSections addEntriesFromDictionary:[NSDictionary dictionaryWithObjectsAndKeys: nestedList, "@Basic", nil]]; [nestedList removeAllObjects]; [nestedList addEntriesFromDictionary:[NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:92], @"menuHeight", @"sendText", @"menuMethod", [NSNumber numberWithInt:1], @"menuOption", nil]]; [nestedSections addEntriesFromDictionary:[NSDictionary dictionaryWithObjectsAndKeys: nestedList, "@Pro", nil]]; </code></pre> <p>I then hoped to address like so;</p> <pre><code>NSString *string = [[nestedSections objectForKey:@"Pro"] objectForKey:@"menuMethod"]; NSLog(@"Method is : %@", string); </code></pre> <p>Log would hope to read <strong>sendText</strong></p> <p>The first dictionary builds fine but as soon as I try and add it to the second t bums out with EXC_BAD_ACCESS</p> <p>I think it is a memory addressing problem because they are both mutable but I am not sure, maybe nestedList should not be mutable. Any help appreciated.</p> <p>Ultimately I would like to convert this to a JSON like;</p> <pre><code>{ "Basic": { "menuHeight":"46", "menuMethod":"editText", "menuOption":"1", }, "Pro": { "menuHeight":"96", "menuMethod":"sendText", "menuOption":"1", } } </code></pre>

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.
