Instance Property


A flag used to determine how a view lays out its content when its bounds change.


var contentMode: UIViewContentMode { get set }


The content mode specifies how the cached bitmap of the view’s layer is adjusted when the view’s bounds change. This property is often used to implement resizable controls. Instead of redrawing the contents of the view every time, you can use this property to specify that you want to scale the contents (either with or without distortion) or pin them to a particular spot on the view.

For a list of values you can assign to this property, see UIViewContentMode. The default value of this property is scaleToFill.
