<pre><code>- (CGRect)frameForImageattribute:(CGSize)image inImageViewAspectFit:(UIImageView *)imageView {
float imageRatio = image.width / image.height;
float viewRatio = imageView.frame.size.width / imageView.frame.size.height;
if (imageRatio < viewRatio) {
float scale = imageView.frame.size.height / image.height;
float width = scale * image.width;
return CGRectMake(kLeftPading, kTopPading, width, imageView.frame.size.height);
}
else {
float scale = imageView.frame.size.width / image.width;
float height = scale * image.height;
return CGRectMake(kLeftPading, kTopPading, imageView.frame.size.width, height);
}
}
</code></pre></p>
