containingLayer

TypeScript

get containingLayer(): _QuartzCore_CALayer

Swift declaration

var containingLayer: CALayer

Containing layer to be rendered into, producing the final frame.

set · iOS 26.0+

containingLayer

TypeScript

set containingLayer(value: _QuartzCore_CALayer)

Swift declaration

var containingLayer: CALayer

Containing layer to be rendered into, producing the final frame.

init · iOS 26.0+

init

TypeScript

static initPostProcessingAsVideoLayerContainingLayer(layer: _QuartzCore_CALayer, containingLayer: _QuartzCore_CALayer): AVVideoCompositionCoreAnimationTool_Configuration

Swift declaration

init(postProcessingAsVideoLayer layer: CALayer, containingLayer: CALayer)

Place composited video frames in videoLayer and render animationLayer to produce the final frame. Normally videoLayer should be in animationLayer's sublayer tree. The animationLayer should not come from, or be added to, another layer tree. Be aware that on iOS, CALayers backing a UIView usually have their content flipped (as defined by the -contentsAreFlipped method). It may be required to insert a CALayer with its geometryFlipped property set to YES in the layer hierarchy to get the same result when attaching a CALayer to a AVVideoCompositionCoreAnimationTool as when using it to back a UIView.

init

TypeScript

static initPostProcessingAsVideoLayersContainingLayer(layers: Array<_QuartzCore_CALayer>, containingLayer: _QuartzCore_CALayer): AVVideoCompositionCoreAnimationTool_Configuration

Swift declaration

init(postProcessingAsVideoLayers layers: [CALayer], containingLayer: CALayer)

Duplicate the composited video frames in each videoLayer and render animationLayer to produce the final frame. Normally videoLayers should be in animationLayer's sublayer tree. The animationLayer should not come from, or be added to, another layer tree. Be aware that on iOS, CALayers backing a UIView usually have their content flipped (as defined by the -contentsAreFlipped method). It may be required to insert a CALayer with its geometryFlipped property set to YES in the layer hierarchy to get the same result when attaching a CALayer to a AVVideoCompositionCoreAnimationTool as when using it to back a UIView.
