How can I add a delay before the animation starts?

[Ricardo1980]

Hello! I'm using something like this: NSBKeyframeAnimation *animation2 = [NSBKeyframeAnimation animationWithKeyPath:@"transform.scale.y" duration:animationDuration startValue:0 endValue:1 function:NSBKeyframeAnimationFunctionEaseOutElastic];

to animate several views at once. My question is, how can I add a delay before the animation starts? I know UIView animation... has a method for that. Thanks a lot, very useful lib.

Hi Ricardo,

You can set an initial delay by setting the beginTime property in the animation object. Like so:

const NSTimeInterval delay = 1.0f;
animation.beginTime = CACurrentMediaTime() + delay;

Works perfectly! BTW, is there any easy way to launch a block when the animation (after the delay) is going to be started? I wanted to add a sound. Thanks.

You can do so by implementing the delegate method.

It works! Although this is strange, CAAnimationDelegate is not an actual protocol.
