Aspect ratio about pinlayout

Hi @Sully73, I've completed the implementation of aspectRatio, check the release 1.3.2: https://github.com/mirego/PinLayout/releases/tag/1.3.2

Hi @Sully73, thanks for the great comment, it's appreciated 👍

The support of aspectRatio is on my todo list.

What will be implemented:

• Add a method aspectRatio(:CGFloat). If the width or the height has been set, the aspectRatio value will be used to compute the other dimension. If neither dimension (width/height) or both have been specified, aspectRatio won't be applied and a warning will be displayed.
• Add a method aspectRatio() that will only work with UIImageView. This method will use the UIImageView's image aspect ratio.

I should be able to play with this week.

For the time being the only option I see is to layout your UIImageView in two operations:

let imageSize = myImageView.image!.size
let imageRatio = imageSize.width / imageSize.height

// Layout the UIImageView without specifiying the height.
myImageView.pin.top(20).left(20).width(50%)
// then adjust the height
myImageView.pin.height(myImageView.frame.width / imageRatio)

Soon you'll be able to do:

myImageView.top(20).left(20).width(50%).aspectRatio()

If you have any comment on my aspectRatio proposition just let me know 🙂
