[转]IFTTT开源Swift编写的帧动画框架RazzleDazzle

RazzleDazzle支持的动画类型：

• AlphaAnimation animates the alpha property (creates fade effects).

• BackgroundColorAnimation animates the backgroundColor property.

• RotationAnimation animates a rotation transform (for rotation effects).

• ScaleAnimation applies a scaling transform (to scale view sizes).

• TranslationAnimation applies a translation transform (to translate view position).

• CornerRadiusAnimation animates the layer.cornerRadius property.

• HideAnimation animates the hidden property (hides and shows views).

• LayerStrokeStartAnimation animates the strokeStart property of a CAShapeLayer (does not work with LayerStrokeEndAnimation).

• LayerStrokeEndAnimation animates the strokeEnd property of a CAShapeLayer (does not work with LayerStrokeStartAnimation).

• LayerFillColorAnimation animates the fillColor property of a CAShapeLayer.

• LayerStrokeColorAnimation animates the strokeColor property of a CAShapeLayer.

• PathPositionAnimation animates the layer.position property of a UIView along a path.

• LabelTextColorAnimation animates the textColor property of a UILabel.

• ConstraintConstantAnimation animates an AutoLayout constraint constant.

• ConstraintMultiplierAnimation animates an AutoLayout constraint constant as a multiple of an attribute of another view (to offset or resize views based on another view‘s size)

• ScrollViewPageConstraintAnimation animates an AutoLayout constraint constant to place a view on a scroll view page (to position views on a scrollView using AutoLayout). This is the animation doing the heavy lifting for AnimatedPagingScrollViewController‘s keepView(view: onPage:) function.
