[Layout] Provide access to .readableContentGuide in -layoutSpecThatFits:

[huy-le]

Hi guys,

I am implementing an iPad version for a screen using ASTableNode. I recognise that there is no support for readable width. Have you guys considered it in near future roadmap?

Cheers.

It is possible to use readable widths within cell nodes by storing the width elsewhere and making use of it within the layout spec. Definitely would be neat to have it more easily available to use though throughout Texture.

@ay8s do you know how can I retrieve readableWidth. All document from Apple just said enable it by code from UITableViewCell. No document tell about how to retrieve these value.

You can grab it via self.view.readableContentGuide.layoutFrame.size.width but you'll need to pass to the cell nodes themselves.

Thank you very much @ay8s I got that value. I am trying to set maxWidth and minWidth in layoutSpecThatFit of CellNode, but seem like it does not change the layout.

Make sure you access self.view.readableContentGuide... within a method that runs on the main thread (e.g. -didLoad for ASDisplayNode subclass). See more here: http://texturegroup.org/docs/subclassing.html

Actually, layout is run before view is loaded, so this solution will result in a relayout pass. :( With the iPhone X, Texture may need to provide a new API to get access inside -layoutSpecThatFits: when that method is called before the view is loaded.

Looks like this functionality was introduced in iOS 9 for iPad, but will also affect iPhone X.
