Question

I run an animation on my buttons where I change i.e. Opacity. When the animation is complete all the button’s Opacity goes back to initial values. The code:

CABasicAnimation animation =  CABasicAnimation.FromKeyPath("opacity");
animation.To = NSNumber.FromFloat( 0.1f );
animation.Duration = animationDuration;
animation.TimingFunction = CAMediaTimingFunction.FromName (CAMediaTimingFunction.EaseOut);

How can I set the animation to stay in the To value?

Answer 1

I don’t see the error in the code, but there is another way to do that instead of CoreAnimation, which is a bit verbose.

For UIKit elements it is usually easier to use the UIView.Animate method. So , your sample would be:

UIView.Animate (
    animationDuration,
    0,
    UIViewAnimationOptions.CurveEaseOut,
    delegate {yourButton.Alpha = 0.1f; },
    null);
