Question

I have a UIImageView with a UIImage inside set to scale aspect ratio. The image is more tall than wide and there is a transparent region on either side of the UIImageView. How can I convert the tap location of the UIImageView to correct locations inside of the UIImage?

Answer 1

you have the original width and height of the image. divide it with the width and height of the view. multiply the factor image.size.height/view.frame.size.height with the y you tapped and image.size.width/view.frame.size.width with the tapped x.
