Can you add a screenshot of your requirement? and what exactly you have done till now? — Anurag Sharma, Jul 10 '17 at 06:49
Did you check imageViewContentMode? try setting content mode to AspectFit/Fill. If possible give more insight on this problem. — Sivajee Battina, Jul 10 '17 at 06:56

Follow steps

setImage to UIImageView (with UIViewContentModeScaleAspectFit)
get imageSize (CGSize imageSize = imageView.image.size)
UIImageView resize. [imageView sizeThatFits:imageSize]

move position where you want.

    CGSize imageSize = imageView.image.size;
    [imageView sizeThatFits:imageSize];
    CGPoint imageViewCenter = imageView.center;
     imageViewCenter.x = CGRectGetMidX(self.contentView.frame);
    [imageView setCenter:imageViewCenter];

set UIImageView size == image (ratio):

@IBOutlet weak var heightConstraint: NSLayoutConstraint!
@IBOutlet weak var widthConstraint: NSLayoutConstraint!

func setImage(image: UIImage) {
    imageView.image = image
    let screenSize = UIScreen.main.bounds.size

    let imageAspectRatio = image.size.width / image.size.height
    let screenAspectRatio = screenSize.width / screenSize.height

    if imageAspectRatio > screenAspectRatio {
        widthConstraint.constant = min(image.size.width, screenSize.width)
        heightConstraint.constant = widthConstraint.constant / imageAspectRatio
    }
    else {
        heightConstraint.constant = min(image.size.height, screenSize.height)
        widthConstraint.constant = heightConstraint.constant * imageAspectRatio
    }
    view.layoutIfNeeded()
}
