How to scale a UIImageView proportionally?

I have a UIImageView and the objective is to scale it down proportionally by giving it either a height or width. UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://farm4.static.flickr.com/3092/2915896504_a88b69c9de.jpg"]]]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; //Add image view [self.view addSubview:imageView]; /
