Is there an way to make a SectionList with Tabs inside a ScrollView?

I'm developing a mobile app with react native, and i'm stuck to make a Visualization like the Image.
I can't get it to work with the ScrollView (witch wraps everything) and the SectionList itself (with tabs).
I need the Tab navigation to stick on the Header while scrolling and continue the scrolling to the sections.
I'm using this library https://github.com/bogoslavskiy/react-native-tabs-section-list, but i can't get it to work.

(iOS) Is it possible to move loading spinner in FlatList refreshing prop?

I am trying to use pull to refresh from FlatList. Is it possible to move the spinner to where the data actually starts rendering instead of the top of the screen? I found the progressViewOffset that works on Android but I am trying to find how I can implement this behaviour on iOS too. I feel like my solution is to watch scroll interactions and go on from there.
Any idea is appreciated. Thanks in advance.

How would a slideable list control like this be achieved with React Native?

The Yelp app for iOS is designed such that after you enter and send a search query, something like this comes up:
The screen consists of a map control in the background, with a screen on top displaying a list view that you can swipe up/down depending on whether you want to see the list/map (respectively).
How would something like this be accomplished using React Native? For example, would the React Navigation or React Native Swiper libraries help me superimpose a list view on top of the map control?
You can use PanResponder.

Changing title In UIWebview as user scrolls

I am developing an iOS app. How can I know the current section that is being displayed in the UIWebview and change the title of the navigation bar accordingly? The title will be the section which the user is reading. The sections in the html file displayed in the UIWebView are separated by <h2> tags.
If anyone is looking for an answer to this, this might help. Its basically done using javascript functions.
