    copied!<p>I am currently adding a <code>UISegmentedControl</code> to the toolbar in the navigation controller programmatically (as seen below).</p> <p>This approach works fine, I have my <code>UISegmentedControl</code>, it fires the selector that I have setup no problems.</p> <p>Problem is - I would like to use the <code>selectedIndex</code> of this control in order to query my data model and present a different view of data for each 'segment' - but I am having trouble getting the <code>selectedIndex</code>.</p> <p>In my travels I have been consulting the 'Top Songs' example code provided by Apple. In this code they build up their interface via <code>UISegmentedControl</code> object in the view controller and IB. In doing so they can access the <code>UISegmentedControl</code>'s <code>selectedIndex</code>. I am adding mine programmactically and do not have this freedom.</p> <p>'SHOULD' I have a <code>UISegmentedControl</code> defined in my view controller? If so, if I want to continue building my menu programmactically, how do I go about accessing the information from the control buried within the navigation controller's <code>UIToolBar</code>?</p> <p>I'm clearly missing something basic. Any assistance is always greatly appreciated :)</p> <pre><code>[self.navigationController setToolbarHidden:NO]; // Set up the edit and add buttons. self.navigationItem.leftBarButtonItem = self.editButtonItem; UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject)]; self.navigationItem.rightBarButtonItem = addButton; [addButton release]; NSArray *tabitems = [NSArray arrayWithObjects:@"ONE", @"TWO", @"THREE", @"FOUR", nil]; UISegmentedControl *tabs = [[UISegmentedControl alloc] initWithItems:tabitems]; [tabs addTarget:self action:@selector(pickedSegment:) forControlEvents:UIControlEventValueChanged]; tabs.segmentedControlStyle = UISegmentedControlStyleBar; tabs.frame = CGRectMake(60, 8, 180, 30); tabs.selectedSegmentIndex = 0; //[self.navigationController.navigationBar addSubview:tabs]; [self.navigationController.toolbar addSubview:tabs]; [tabs release]; </code></pre>
