Available on crate feature AVCaptureSession only.

Defines an interface for delegates of AVCaptureSession to receive events about the session’s controls.

Provided Methods

unsafe fn sessionControlsDidBecomeActive(&self, session: &AVCaptureSession)

where Self: Sized + Message,

Called when the controls of an AVCaptureSession instance become active and are available for interaction.

Parameter session: The AVCaptureSession instance whose controls are active.

Delegates receive this message when the controls of an AVCaptureSession instance become active and are available for interaction.

unsafe fn sessionControlsWillEnterFullscreenAppearance( &self, session: &AVCaptureSession, )

where Self: Sized + Message,

Called when the controls of an AVCaptureSession instance will enter a fullscreen appearance.

Parameter session: The AVCaptureSession instance whose controls will enter a fullscreen appearance.

When the controls enter a fullscreen appearance, applications are encouraged to hide portions of their user interface including zoom or exposure sliders and shutter buttons. Few on-screen elements should be visible so users can focus on the controls they are interacting with and view the camera preview unobstructed.

unsafe fn sessionControlsWillExitFullscreenAppearance( &self, session: &AVCaptureSession, )

where Self: Sized + Message,

Called when the controls of an AVCaptureSession instance will exit a fullscreen appearance.

Parameter session: The AVCaptureSession instance whose controls will exit a fullscreen appearance.

Delegates receive this message when the controls of an AVCaptureSession instance should resume showing portions of their user interface that were hidden in response to receiving -sessionControlsWillEnterFullscreenAppearance:. This message is sent before sessionControlsDidBecomeInactive:.

unsafe fn sessionControlsDidBecomeInactive(&self, session: &AVCaptureSession)

where Self: Sized + Message,

Called when the controls of an AVCaptureSession instance become inactive and are no longer available for interaction.

Parameter session: The AVCaptureSession instance whose controls are inactive.

Delegates receive this message when the controls of an AVCaptureSession instance become inactive and are no longer available for interaction.
