Mapping of React Native components in iOS

We're trying to do automated testing of React Native application. For that, we want to figure out which React Native component maps to what iOS components. So far I can see that:

• Image (React) maps to RCTImageView/UIImageView (iOS)
• ScrollView (React) maps to RCTCustomScrollView/UIScrollView (iOS)

What about TouchableOpacity and View? How is that rendered on iOS? Where can I find a full list of these mappings?
