.ScaleAspectFit query could be more lucid

[kayoslab]

Very confusing implementation of the .ScaleAspectFit behaviour. This could be more lucid.

if (subview.isKindOfClass(UIImageView)) {
    if let image = imageView.image {
        if (imageView.contentMode == .ScaleAspectFit) {
            if (image.size.width > imageView.frame.size.width || image.size.height > imageView.frame.size.height) {
                if (image.size.width < image.size.height) {
                    // Landscape format
                    if (ratioWidth > imageView.frame.size.width) {
                        // Portrait does not fit into subview:UIImageView
                    } else {
                        // Portrait fits into subview:UIImageView
                    }
                } else {
                    // Portrait format
                    if (ratioHeight > imageView.frame.size.height) {
                        // Landscape does not fit into subview:UIImageView
                    } else {
                        // Landscape fits into subview:UIImageView
                    }
                }
            } else {
                // Image is smaller than subview:UIImageView
            }
        } else {
             // contentMode is not .ScaleAspectFit
        }
    }
}
