Sent to the view controller just before the user interface begins rotating.
The duration of the pending rotation, measured in seconds.
Subclasses may override this method to perform additional actions immediately prior to the rotation. For example, you might use this method to disable view interactions, stop media playback, or temporarily turn off expensive drawing or live updates. You might also use it to swap the current view for one that reflects the new interface orientation. When this method is called, the
interfaceOrientation property still contains the view's original orientation. Your implementation of this method must call
super at some point during its execution.
This method is called regardless of whether your code performs one-step or two-step rotations.
Called just before releasing the controller's view from memory.
Called when the controller's view is released from memory.
A Boolean value indicating whether the view should underlap the status bar.
Returns the header view to transition during an interface orientation change.
Returns the footer view to transition during an interface orientation change.
Convenience property that provides the current orientation of the interface, meaningful only if the view controller is taking up the full screen.
The controller for the active presented view'that is, the view that is temporarily displayed on top of the view managed by the receiver.
Indicates the lowest vertical extent for your onscreen content, for use with Auto Layout constraints.
Indicates the highest vertical extent for your onscreen content, for use with Auto Layout constraints.
A boolean value that indicates whether the view controller is configured to display banner ads.
The originally configured content view of the view controller before banner ads were enabled.
A boolean value that indicates whether the view controller is displaying a full-screen ad.
A boolean value that indicates whether the view controller is displaying a banner ad.
Prepares the iAd framework to display interstitial ads, which may involve prefetching ad assets.
Determines whether interstitials should be presented at all and whether the framework or app should manage the presentation.
