Declaration
@property(nonatomic, readwrite) vectorDiscussion
Together with the translation, rotation, and shear properties, this property defines the local coordinate space for any object affected by the transform, relative to a parent coordinate space. Use the matrix property to work with the complete transform.
If the transform includes time-based information, reading this property returns the scale as of the earliest time sample (as reported by the minimum property). Writing to this property erases any time-sampled data for the scale factor. To work with time-sampled data from an animated transform, use the scale and set methods.
