I have this code to animate a CALayer element.
CABasicAnimation *makeBiggerAnim=[CABasicAnimation animationWithKeyPath:@"radius"];
makeBiggerAnim.duration=0.2;
makeBiggerAnim.fromValue=[NSNumber numberWithDouble:20.0];
makeBiggerAnim.toValue=[NSNumber numberWithDouble:40.0];
makeBiggerAnim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
My question is, now everything works fine, I would like another attribute of the same element at the same time. I've seen you can do additive animations and stuff.
My question is:
Thanks!
You can create an CAAnimationGroup
and customize the duration and timing function on it. Then you create all your CABasicAnimations
, set their to value and add them to the animation group. Finally, you add the animation group to the layer that you are animating.
Here an example:
CABasicAnimation *makeBiggerAnim=[CABasicAnimation animationWithKeyPath:@"cornerRadius"];
makeBiggerAnim.fromValue=[NSNumber numberWithDouble:20.0];
makeBiggerAnim.toValue=[NSNumber numberWithDouble:40.0];
CABasicAnimation *fadeAnim=[CABasicAnimation animationWithKeyPath:@"opacity"];
fadeAnim.fromValue=[NSNumber numberWithDouble:1.0];
fadeAnim.toValue=[NSNumber numberWithDouble:0.0];
CABasicAnimation *rotateAnim=[CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
rotateAnim.fromValue=[NSNumber numberWithDouble:0.0];
rotateAnim.toValue=[NSNumber numberWithDouble:M_PI_4];
// Customizing the group with duration etc, will apply to all the
// animations in the group
CAAnimationGroup *group = [CAAnimationGroup animation];
group.duration = 0.2;
group.repeatCount = 3;
group.autoreverses = YES;
group.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
group.animations = @[makeBiggerAnim, fadeAnim, rotateAnim];
[myLayer addAnimation:group forKey:@"allMyAnimations"];
