Type Method


Returns the layout direction implied by the specified semantic content attribute, relative to the specified layout direction.


class func userInterfaceLayoutDirection(for semanticContentAttribute: UISemanticContentAttribute, relativeTo layoutDirection: UIUserInterfaceLayoutDirection) -> UIUserInterfaceLayoutDirection



The semantic content attribute for a view.


Return Value

The layout direction implied by the semantic content attribute and relative to the layout direction.


For example, when this method is passed a layout direction of UIUserInterfaceLayoutDirection.rightToLeft and a semantic content attribute of UISemanticContentAttribute.playback, it returns UIUserInterfaceLayoutDirection.leftToRight. Although layout and drawing code can use this method to determine how to arrange elements, it might be easier to query the container view’s effectiveUserInterfaceLayoutDirection property instead.
