The following CALayer class properties can be animated by Core Animation. See CALayer for more information.

anchorPoint
Uses the default implied CABasicAnimation described in Table 10.
backgroundColor
Uses the default implied CABasicAnimation described in Table 10. (subproperties are animated using a basic animation)
backgroundFilters
Uses the default implied CATransitionAnimation described in Table 11. Sub-properties of the filters are animated using the default implied CABasicAnimation described in Table 10.
borderColor
Uses the default implied CABasicAnimation described in Table 10.
borderWidth
Uses the default implied CABasicAnimation described in Table 10.
bounds
Uses the default implied CABasicAnimation described in Table 10.
compositingFilter
Uses the default implied CATransitionAnimation described in Table 11. Sub-properties of the filters are animated using the default implied CABasicAnimation described in Table 10.
contents
contentsRect
Uses the default implied CABasicAnimation described in Table 10.
cornerRadius
Uses the default implied CABasicAnimation described in Table 10.
doubleSided
No default implied animation is set.
filters
Uses the default implied CABasicAnimation described in Table 10. Sub-properties of the filters are animated using the default implied CABasicAnimation described in Table 10.
frame
The frame property itself is not animatable. You can achieve the same results by modifying the bounds and position properties instead.
hidden
Uses the default implied CABasicAnimation described in Table 10.
