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 UIImageView dynamically.

I am using this code to change the image:

self.imageView.image = [UIImage imageNamed:@"setting-image.png"];

The problem is, when the *.png image size is smaller than the UIImageView frame size, the image stretches. I don’t want it to stretch. Is there any way to do that?

Answer 1

You can use

self.imageView.contentMode = UIViewContentModeScaleAspectFit;

Swift 3:

imageView.contentMode = .scaleAspectFit

Or UIViewContentModeCenter / .center, or any of the other modes described in the UIView documentation.
