Is it possible to generate iOS autolayout code?

Hi, this js lib looks very interesting. Just a question, I'm wondering if iOS code can be generated, either swift for obj-c version. So that we can write a web application and generate views can be used in iOS app. Any thoughts about it?

Hi, yes you could do this. When you create an Autolayout.js View, you can add constraints to it. Either by creating them explicitly or by creating them from a VFL string. Unfortunately there is no method to get the constraints from a view (yet), but you could easily keep track of the added constraints yourself.
These constraints have exactly the same properties as NSLayoutConstraint, so you could easily write some code to format them as Objective-C/Swift constraints.

Cool, this is exciting. Can you point me to the code where I can do the conversion maybe? I took a look at the source code, but not sure where is the best start point...

Sure, that would be src/VisualFormat.js. VisualFormat.parse() parses VFL or EVFL and returns a list of objects (constraint definitions).
