GTEasyLayoutAdaptable

public protocol GTEasyLayoutAdaptable

Layout views, apply constraints and update them easily by using the methods specified in the GTEasyLayoutAdaptable protocol. An extension with default implementation is included for instant usage of the protocol.

  • add(view:to:snapTo:padding:size:) Default implementation

    Undocumented

    Default Implementation

    It adds the given view as a subview to the target view, snapping it to the specified edges and applying spacing on each side as described by the padding parameter value.

    All edge values except for the all case require the width, the height, or both to have a proper value in the size parameter. In case there’s no need to provide them, then just pass a zero size (CGSize.zero).

    See the GTEasyLayout.SnapEdges enumeration for available values regarding edge snapping. To center a view both horizontally and vertically provide the centerX_Y edge along with a valid size for it.

    Use the padding parameter value to add some spacing to each side of the view. If no spacing is necessary, pass a zero edge insets value (UIEdgeInsets.zero).

    When using any combination of snap edges which includes horizontal or vertical centering (centerX or centerY), then provide only the left and top values of the padding property, right and bottom are disregarded. To add padding to the left set a positive value to the left parameter of the edge insets; to add padding to the right set a negative value instead. Accordingly, in vertical axis provide a positive value to top parameter of the edge insets so the view is pushed down; give a negative value to push it up.

    Note that this method takes into account the safe area of the screen.

    Declaration

    Swift

    func add(view: UIView, to targetView: UIView, snapTo edges: GTEasyLayout.SnapEdges, padding: UIEdgeInsets, size: CGSize)

  • Undocumented

    Default Implementation

    Update the padding at the specified side of the given view by applying a new value. Optionally provide customized animation settings and a completion handler.

    Declaration

    Swift

    func updatePadding(at side: GTEasyLayout.Side, ofView view: UIView, newValue: CGFloat, animationSettings: GTEasyLayout.AnimationSettings?, completion: (() -> Void)?)

  • Undocumented

    Default Implementation

    Update the width or height constraint of the given view to the new value.

    Declaration

    Swift

    func updateDimension(_ dimension: GTEasyLayout.Dimension, ofView view: UIView, newValue: CGFloat, animationSettings: GTEasyLayout.AnimationSettings?, completion: (() -> Void)?)
