Question

I have a UIImageView whose frame, set before the image is loaded, is always too large for the image, so when I try to round the corners, for example, nothing happens.

How can I resize the frame so it’s the same size as the underlying image, while ensuring that the center point of the UIImageView does not change?

Answer 1

If you change the bounds of a UIView the center will not change.

CGRect bounds;

bounds.origin = CGPointZero;
bounds.size = newImage.size;

imageView.bounds = bounds;
imageView.image = newImage;
