    <p>Chris already provided a great answer but there are a couple of points I want to add to adress specific questions.</p> <p>iOS apps normally only have a single UIWindow. Within that window you may present multiple views. </p> <p>Apps are normally organized into several logical screens worth of content, each managed by some UIViewController subclass.</p> <p>Each UIViewController instance has a root view which may contain many subviews. A UIViewController's view is expected to fill its window or some frame provided by one of Apple's container view controller classes (UINavigationController, UITabBarController, UISplitViewController, and so on). You should not add one UIViewController's view as a subview of another UIViewController's view.</p> <p>UIViewControllers will attempt to unload their views when the application receives a memory warning if the view is not visible. See the class' life cycle methods like <code>-viewDidUnload</code>. You should support and take advantage of this behavior to reduce your memory footprint. Keeping UIViewControllers in memory without their views loaded should have a minimal overhead, allows you to keep some persistent state, and each controller's view can be reloaded when needed.</p> <p>Normally to transition between views a control will send a message to the current view controller (often via an IBAction binding). The current controller will then trigger a transition to another view controller. It might do so by creating a new view controller and pushing it onto the current navigation controller or presenting the new controller as a modal. It might have a reference to some existing controller and present that. It might dismiss itself from a navigation stack to reveal the previous controller. It might even pass the message up the controller's hierarchy until some parent switches the visible tab, dismisses or presents a modal, and so on.</p> <p>You might also trigger smaller transitions by responding to an IBAction by adding, removing, hiding, or moving subviews of a UIViewController's root view.</p>

    1. COI have been reading some of the documentation Chris provided me and I get most of what you say, unfortunately I'm still stuck... I thought that I needed a Navigation Based App, but most of the examples use a Table View, and I have no use for such thing... Also the documentation is full of text and no code examples... I don't know how to do something as simple as a main menu with 3 buttons that lead to different screens... I still can't achieve that, any idea?

    2. COA navigation based app sounds like the right structure. Create a navigation controller with your existing view controller as its root controller. Have your IBAction methods which respond to those buttons push new view controllers onto the navigation controller.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
