How to change image's size? Image does not fill

问题

I'm trying to make the image rounded. It is already 128x128 (width and height) and the corner radius is 64. I want to zoom in before cutting the photo to take the full rounded size of the picture.

How to zoom it?

My code:

profileImage.layer.cornerRadius = 64
profileImage.clipsToBounds = true

I want to make it like this:

回答1:

You should set the UIImageView's content mode to .scaleAspectFill. That way, the image will fill up the whole container without distorting it.

profileImage.contentMode = .scaleAspectFill

回答2:

please first ensure your image height and width must be equal. and constraint set properly

after that change below to line

profileImage.layer.cornerRadius = profileImage.frame.size.width/2
profileImage.clipsToBounds = true
