Instance Property

autoresizingMask

A bitmask defining how the layer is resized when the bounds of its superlayer changes.

Declaration

@property CAAutoresizingMask autoresizingMask;

Discussion

If your app does not use a layout manager or constraints to handle layout changes, you can assign a value to this property to adjust the layer’s size in response to changes in the superlayer’s bounds. For a list of possible values, see CAAutoresizingMask.

The default value of this property is kCALayerNotSizable.
