Summary: FIXES https://github.com/facebook/react-native/issues/45858 When working with UIRefreshControl in a custom React Native component, we encountered a problem where the refresh control did not behave correctly if it was offscreen. Specifically, attempts to programmatically begin or end refreshing were ignored if the control was not visible. This typically manifested as the refresh control not updating its state properly when it was re-rendered or moved in the view hierarchy. Happening only on old-arch. **Problem Details** **Offscreen Refresh Control Ignored:** The UIRefreshControl would ignore calls to beginRefreshing and endRefreshing if it was not currently visible on the screen. **Inconsistent State:** The internal state _currentRefreshingState might not match the actual state of the UIRefreshControl, leading to unexpected behavior. **Steps to Fix** **Track Visibility with didMoveToWindow:** Implement the didMoveToWindow method to track when the refresh control is added to or removed from the window. Use a flag _hasMovedToWindow to keep track of this state. And check this flag should be true whenever we start or end refreshing ## Changelog: [IOS] [FIXED] - Fixed an issue where the refresh control would not behave correctly if it was offscreen.

React Native
Learn once, write anywhere:
Build mobile apps with React.
Getting Started · Learn the Basics · Showcase · Contribute · Community · Support
React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 13.4 and Android 6.0 (API 23) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
