    <p>I have a couple of questions regarding the code below:</p> <p>(1) Is "newItem" an autoreleased object? Its getting a returned dictionary from the specified array index?</p> <p>(2) Is there a simple way to access an array of dictionarys in one hit, or am I doing it the way you would expect?</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; NSMutableArray *menu = [[NSMutableArray alloc] init]; NSMutableDictionary *menuItem; NSMutableDictionary *newItem; NSArray *itemName = [NSArray arrayWithObjects: @"Latte Medio", @"Cappucion Medio", @"Mocha Medio", @"Vanilla Latte Medio",nil]; NSArray *itemFat = [NSArray arrayWithObjects: [NSNumber numberWithFloat:6.9], [NSNumber numberWithFloat:4.7], [NSNumber numberWithFloat:6.6], [NSNumber numberWithFloat:6.9],nil]; NSArray *itemCals = [NSArray arrayWithObjects: [NSNumber numberWithInt:516], [NSNumber numberWithInt:408], [NSNumber numberWithInt:624], [NSNumber numberWithInt:743],nil]; NSLog(@"DICTARRAY ... Start"); // Create menuItem object menuItem = [[NSMutableDictionary alloc] init]; [menuItem setObject:[itemName objectAtIndex:0] forKey:@"product"]; [menuItem setObject:[itemFat objectAtIndex:0] forKey:@"fat"]; [menuItem setObject:[itemCals objectAtIndex:0] forKey:@"calories"]; // Add menuItem object to menu [menu addObject:menuItem]; [menuItem release], menuItem = nil; // Access menu to get menuItem newItem = [menu objectAtIndex:0]; NSLog(@"DATA: %@",[newItem objectForKey:@"product"]); NSLog(@"DATA: %@",[newItem objectForKey:@"fat"]); NSLog(@"DATA: %@",[newItem objectForKey:@"calories"]); // Clean up [menu release], menu = nil; [pool drain]; return 0; } </code></pre> <p>gary</p>

    1. COThe first bit (where the arrays are initialised) is just me setting up some temp data. The actual data structure used is an array of dictionary objects (I guess I could have used custom objects here).

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.
