Get height based on fixed width UIImageView image

How can I get height for UIImageView based on fixed (310.0f) UIImageView width for real looking image ?

So the thing should work for placing UIImageViews in UITableViewCells (thats not important for question). But I want to point on some examples: 9gag app, facebook, google+ and other feeds with images that resize and are put in UITableViewCell

Divide the width you want by the actual width of the image. Then multiple that number with the actual height.

UIImage* image = [UIImage imageNamed:@"someImage.png"];
CGSize imageSize = image.size;
CGFloat newHeight = (310.0 / imageSize.width) * imageSize.height;
