I don't even see a button class in React Native... but if there was one and it was custom-made from UIViews, it's going to look and act differently than a native button. Turn on accessibility features -- does the button's title get read aloud? If you turn on button highlighting, does the button get an outline? If you turn on bold text or large text, does the text of the button change?

I've spent 15 minutes with React Native so far, and as best I can figure, the answer is no.

If they were building the GUI components from UIKit pieces, they'd get all of this for free. But I understand it would be pretty hard to get all this working with the flexible layout architecture they have... so I'm guessing they'll have to slow add all the accessibility features in over time.
