How to stop an image from stretching within a UIImageView?

Question

I have a UIImageView where I have set the frame size to x = 0, y = 0, width = 404, height = 712. In my project, I need to change the image in

Answer 1

Use this for your UIImageView

imageView.contentMode = UIViewContentModeScaleAspectFill;

You won't get any space and with scale preserved. However, some part of the image will be clipped off.

If you use the following:

imageView.contentMode = UIViewContentModeScaleAspectFit;

There will be some empty space, but scale is preserved.
