The timing function used for all animations within this animation proxy group.
- macOS 10.7+
The NSAnimationContext timing function is analogous to the CATransaction
Animations initiated through the “animator” proxy syntax, that do not have an explicitly specified timing functions, will inherit the enclosing
timing if it is not
nil (which is the default).
Also as with the
duration property, you may change the timingFunction any number of times within a given NSAnimationContext
end block. Changes to the
timing will apply to any animations that are subsequently initiated in that NSAnimationContext grouping, until the
timing is possibly changed again.
