/*! @class CPViewController
|
||||
The CPViewController class provides the fundamental view-management controller for Cappuccino applications.
|
||||
The basic view controller class supports the presentation of an associated view in addition to basic support
|
||||
for managing modal views and, in the future, animations. Subclasses such as CPNavigationController and
|
||||
CPTabBarController provide additional behavior for managing complex hierarchies of view controllers and views.
|
||||
|
||||
You use each instance of CPViewController to manage a single view (and hierarchy). For a simple view controller,
|
||||
this entails managing the view hierarchy responsible for presenting your application content.
|
||||
A typical view hierarchy consists of a root viewÑa reference to which is available in the view property of this classÑ
|
||||
and one or more subviews presenting the actual content. In the case of navigation and tab bar controllers, the view
|
||||
controller manages not only the high-level view hierarchy (which provides the navigation controls) but also one
|
||||
or more additional view controllers that handle the presentation of the application content.
|
||||
|
||||
Unlike UIViewController in Cocoa Touch, a CPViewController does not represent an entire screen of content. You
|
||||
will add your root view to an existing view or window's content view. You can manage many view controllers
|
||||
on screen at once. CPViewController is also the preferred way of working with Cibs.
|
||||
|
||||
Subclasses can override -loadView to create their custom view hierarchy, or specify a cib name to be loaded automatically.
|
||||
It has methods that are called when a view appears or disappears.
|
||||
This class is also a good place for delegate & datasource methods, and other controller stuff.
