How to stop an image from stretching within a UIImageView?

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?

Solution

  • 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.
