    <p>I'm only new to iPhone development, so my apologies if this is a silly question. I'm building various apps based on a book I'm reading and one of their suggestion was to build a mini web browser. I thought this would be easy, but while most of it is, I'm seriously struggling with the <code>NSDictionary</code>.</p> <p>I have a <code>UISegmentedControl</code> used to display various bookmarks. The bookmark name that is displayed on the buttons of the <code>UISegmentedControl</code> is going to be my key and the url is the value associated with it.</p> <p>I first try to declare an <code>NSDictonary</code> as a private (global variable), but since I could not get it to work, I resorted to declare it in my header file as follows:</p> <pre><code>@property (nonatomic, retain) NSDictionary *bookmarks; </code></pre> <p>I synthesize it and I initialized it in the viewDidLoad as follows:</p> <pre><code>- (void)viewDidLoad { bookmarks = [NSDictionary dictionaryWithObjectsAndKeys:@"http://www.microsoft.com", @"Microsoft", @"http://www.google.com", @"Google", @"http://www.apple.com", @"Apple", @"http://msdn.microsoft.com", @"MSDN", nil]; [super viewDidLoad]; } </code></pre> <p>I then associated a control with my segmented control and when the event is triggered and the function is called I've got the following code which is called:</p> <pre><code>- (IBAction) getShortcut:(id)sender { NSString *shortcut; shortcut = [shortcuts titleForSegmentAtIndex:shortcuts.selectedSegmentIndex]; NSString *url = [bookmarks valueForKey:shortcut]; //[self navigateTo: url]; [url release]; } </code></pre> <p>When a button from the <code>UISegmentedControl</code> is clicked, I extract the value and stored it into shortcut and then I try to use the shortcut variable as a key to extract the associated value from the <code>NSDictionary</code> "bookmarks" but <strong>it keeps crashing on</strong> <code>NSString *url = [bookmarks valueForKey:shortcut];</code> and bombs out of my function and displays the usual error EXC_BAD_ACCESS</p> <p>Any help would be greatly appreciated.</p> <p>T.</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.
