Actually, when the image is showed, its size(instance of Image) doesn't change unless you call compressing image functions.

The only problem is how it's drawn on ImageView. When you use aspect fit to imageview, the image is drawn keeping its own rate between width and height based on the larger one of width and height of ImageView.

So, how to calculate the drawn image size is showed above by @Luan Tran.

Thanks

Hope it help

You can use this

 CGSize imageViewSize = imageView.bounds.size;
 CGSize imageSize = image.size;
 CGFloat minFactor = imageViewSize.width / imageSize.width;
 if (imageViewSize.height / imageSize.height < minFactor) 
 {
     minFactor = imageViewSize.height / imageSize.height;
 }

 CGSize resultSize = CGSizeMake(minFactor * imageSize.width, minFactor * imageSize.height);

Hope it help.
