Views not released in Teacup #125

Closed ghost closed 10 years ago

ghost commented 11 years ago

It seems that when a ViewController containing a Teacup view is released, the Teacup-created views are still retained and leaked.

See my sample app illustrating this problem here: https://github.com/paulcarpenterSE/RubymotionLeaks

Things become even clearer in the sample app when you sublclass the UILabels like so:

class RMLabel < UILabel
  def dealloc
    puts "dealloc!"
    super
  end
end

With the subclass, the non-Teacup RMLabel displays a dealloc message when appropriate, and the Teacup-generated RMLabel displays no message.

This is kind of a big deal. I've been able to verify this as well.

I'll look into what might be causing it.

I should note that this appears to have been resolved. There was a memory leak in the cache that Colin fixed a while ago (2.1.2 I think?) once we actually dove down into detail.
