Equally Space Views

Open a2 opened this issue 11 years ago • 2 comments

What's the easiest way to equally space views with RCL? Would I just align each view’s left side to the previous view’s right side?

You'd have to follow the same general algorithm that manual layout would use. Roughly:

  1. Divide the available space by the number of views (and spacers) you have.
  2. Assign each view to one of those spaces.

We should add an operator for this, but it'll basically just do that same thing.

I recently had to do something similar using RCL, and this is how I did it:

  • Create an initial signal that contains the origin of the point at which you want to begin laying out the views
  • Loop through the views you want to space and create a new origin signal for each one that uses operators on the initial signal to offset the origin by x points in whatever direction(s) (using -moveRight: etc).
  • Use RACSignal +rectsWithOrigin:size: to create a CGRect signal using your modified origin signal and a signal that sends a variable or constant size for the view and bind that to the rcl_frame.

Another approach like you mentioned is to have each iteration create a signal that's dependent on the preview's view's signal, offsetting it by a constant amount instead of having to use the view index to calculate the offset for that particular space. Hope this helps!
