I have an UIImageView with an image. Now I have a completely new image (graphic file), and want to display that in this UIImageView. If I just set 

myImageView.image = newImage;

the new image is visible immediately. Not animatable.

I want it to nicely fade into the new image. I thought maybe there's a better solution than just creating a new UIImageView on top of that and blending with animation?
