Fade In and Fade out in Animation Swift

Question

I have an UIImageView with an Animation and, in the UIView, I apply a fadeIn effect, but I need to apply fade out when the UIImageView, which is animated, when is touched.

This is what I make to fade in.

UIView.animateWithDuration(0.5, delay: delay, 
    options: UIViewAnimationOptions.CurveEaseOut, animations: {
        uiImageView.alpha = 1.0
        }

Answer 1

This is what I would do based on my research: (Supposing you're using storyboard)

1. Go to your UIImageView, and under the Attributes, check the "User Interaction Enabled" checkbox.

2. Drag a TapGestureRecognizer on top of the image view.

3. Control click on the Tap Gesture and drag to make a action on your ViewControler.swift.

4. Add the following code inside:

   UIView.animate(withDuration: 0.5, delay: 0.5, options: .curveEaseOut, animations: {
       self.uiImageView.alpha = 0.0
   }, completion: nil) 
   

Then you're done!
