Fade In and Fade out in Animation Swift

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
        }
Solution

  • 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!
