DirectionSortFunction

public protocol DirectionSortFunction: DistanceSortFunction

A DistanceSortFunction that defines it’s distancePoint based on a Direction. Any distance based sort functions that use a direction variable in order to determine the setup of the animation should implement this protocol.

  • the direction that the animation should follow

    Declaration

    Swift

    var direction: Direction

  • the direction that the animation should follow

    Declaration

    Swift

    public func distancePoint(view: UIView, subviews: [View] = []) -> CGPoint

    Parameters

    view

    the view for which the point coordinates will base their values off of
    subviews

    the subviews that are allocated for the SortFunction. The reason these are passed into the function is so that you can actually grab a reference point of a subview that is closest to the comparison point. This is done so that at least one view will start at the 0s marker.

    Return Value

    a CGPoint object that will allow all views to compare their reference point to this returned value. If translate was used, this returned value should be equal to one of the subviews reference points.
