    <p>I tried to find a solution here but was unable to, basically I have an interactive subview that I need to switch to a new interactive subview from within the subview. I am able to change subviews easily with an IBAction in the main view, but I have been unsuccessful changing the view from within the subview. Here's the code... which should make what I am trying to accomplish more clear.</p> <p>in .h of MainViewController</p> <pre><code>@interface MainViewController : UIViewController { IBOutlet OneViewController *oneviewController; IBOutlet TwoViewController *twoViewController; } -(IBAction)goToView; @property (nonatomic, retain) IBOutlet OneViewController *oneviewController; @property (nonatomic, retain) IBOutlet TwoViewController *twoViewController; @end </code></pre> <p>in .m</p> <pre><code>@implementation MainViewController @synthesize oneviewController; @synthesize twoViewController; -(IBAction)goToView { [self.view addSubview:twoViewController.view]; } - (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:oneviewController.view]; } </code></pre> <p>Ok this all works great, i am able to load both ViewControllers with xib and all their` buttons work etc. ..<br> But when I try...</p> <p>in .m of OneViewController</p> <pre><code>#import "MainViewController" ... [MainViewController.view addSubview:twoViewController.view]; ... </code></pre> <p>this does not work, I have tried a variety of things, by adding the twoViewController to the .h of oneViewController, but it crashed... I am still very new to all this so It is likely I am missing the obvious. Thanks for help!!</p> <p>I also tried this in the .m of OneViewController</p> <p>but it still crashed... although the build succeeded </p> <p><code>MainViewController* mySuperView = (MainViewController*)self.view.superview; TwoViewController *twoViewController; [mySuperView.view addSubview:twoViewController.view];</code></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.
