Body
You could add a <code>property</code> to your <code>SubNavView</code> class that will hold the tag of the button pressed. Then, when you create an instance of <code>SubNavView</code> set that property before showing it. You will also need to save the selected tag in an ivar of <code>MainNavView</code> so you can set the selected tag in <code>SubNavView</code>. Here is an example: SubNavViewController.h <pre><code>@interface SubNavViewController : UIViewController @property (nonatomic, strong) NSInteger tagSelected; // The rest of your class declaration @end </code></pre> MainNavViewController.m <pre><code>@interface MainNavViewController () // This is the ivar to save the selected tag @property (nonatomic, strong) NSInteger tagSelected; @end @implementation MainNavViewController () // Your class code -(IBAction)pushButton:(id)sender { int theTag = ((UIView *) sender).tag; // save the tag that was selected for later use sefl.tagSelected = theTag; switch (theTag) { // The rest of your switch here... } } - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { // Make sure your segue name in storyboard is the same as this line if ([[segue identifier] isEqualToString:@"segueToSubNav"]) { // Get reference to the destination view controller SubNavViewController *vc = [segue destinationViewController]; // Tell SubNavView which button was pressed... vc.selectedTag = self.selectedTag; // Pass any objects to the view controller here, like... [vc setMyObjectHere:buttons]; } } @end </code></pre> After that, when <code>SubNavView</code>'s <code>viewDidLoad</code> is called you can use an <code>if-else</code> clause to create your buttons: <pre><code>-(void)viewDidLoad { [super viewDidLoad]; if (self.selectedTag == 1) { //Do something... } else if (self.selectedTag == 2) { //Do something else... } // etc... } </code></pre> Hope this helps!

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.
