React NativeNative iOS Components
With React Native, you can use the standard platform components such as UITabBar and UINavigationController on iOS. This gives your app a consistent look and feel with the rest of the platform ecosystem, and keeps the quality bar high. These components are easily incorporated into your app using their React component counterparts, such as TabBarIOS and NavigatorIOS.

React Native | A framework for building native apps with React Gesture Responder System
Gesture recognition on mobile devices is much more complicated than web. A touch can go through several phases as the app determines what the user's intention is. For example, the app needs to determine if the touch is scrolling, sliding on a widget, or tapping. This can even change during the duration of a touch. There can also be multiple simultaneous touches.
The touch responder system is needed to allow components to negotiate these touch interactions without any additional knowledge about their parent or child components. This system is implemented in ResponderEventPlugin.js, which contains further details and documentation.
Best Practices #
Users can feel huge differences in the usability of web apps vs. native, and this is one of the big causes. Every action should have the following attributes:
- Feedback/highlighting- show the user what is handling their touch, and what will happen when they release the gesture
- Cancel-ability- when making an action, the user should be able to abort it mid-touch by dragging their finger away
These features make users more comfortable while using an app, because it allows people to experiment and interact without fear of making mistakes.
TouchableHighlight and Touchable* #
The responder system can be complicated to use. So we have provided an abstract Touchable implementation for things that should be "tappable". This uses the responder system and allows you to easily configure tap interactions declaratively. Use TouchableHighlight anywhere where you would use a button or link on web.
Responder Lifecycle #
A view can become the touch responder by implementing the correct negotiation methods. There are two methods to ask the view if it wants to become responder:
View.props.onStartShouldSetResponder: (evt) => true, - Does this view want to become responder on the start of a touch?View.props.onMoveShouldSetResponder: (evt) => true, - Called for every touch move on the View when it is not the responder: does this view want to "claim" touch responsiveness?
If the View returns true and attempts to become the responder, one of the following will happen:
View.props.onResponderGrant: (evt) => {} - The View is now responding for touch events. This is the time to highlight and show the user what is happeningView.props.onResponderReject: (evt) => {} - Something else is the responder right now and will not release it
If the view is responding, the following handlers can be called:
View.props.onResponderMove: (moveEvt) => {} - The user is moving their fingerView.props.onResponderRelease: (releaseEvt) => {} - Fired at the end of the touch, ie "touchUp"View.props.onResponderTerminationRequest: (evt) => true - Something else wants to become responder. Should this view release the responder? Returning true allows releaseView.props.onResponderTerminate: (evt) => {} - The responder has been taken from the View. Might be taken by other views after a call to onResponderTerminationRequest, or might be taken by the OS without asking (happens with control center/ notification center on iOS)
Capture ShouldSet Handlers #
onStartShouldSetResponder and onMoveShouldSetResponder are called with a bubbling pattern, where the deepest node is called first. That means that the deepest component will become responder when multiple Views return true for *ShouldSetResponder handlers. This is desirable in most cases, because it makes sure all controls and buttons are usable.
However, sometimes a parent will want to make sure that it becomes responder. This can be handled by using the capture phase. Before the responder system bubbles up from the deepest component, it will do a capture phase, firing on*ShouldSetResponderCapture. So if a parent View wants to prevent the child from becoming responder on a touch start, it should have a onStartShouldSetResponderCapture handler which returns true.
View.props.onStartShouldSetResponderCapture: (evt) => true,View.props.onMoveShouldSetResponderCapture: (evt) => true,

React Native | A framework for building native apps with React Native Modules (iOS)
Sometimes an app needs access to platform API, and React Native doesn't have a corresponding wrapper yet. Maybe you want to reuse some existing Objective-C or C++ code without having to reimplement it in JavaScript. Or write some high performance, multi-threaded code such as image processing, network stack, database or rendering.
We designed React Native such that it is possible for you to write real native code and have access to the full power of the platform. This is a more advanced feature and we don't expect it to be part of the usual development process, however it is essential that it exists. If React Native doesn't support a native feature that you need, you should be able to build it yourself.
This is a more advanced guide that shows how to build a native module. It assumes the reader knows Objective-C (Swift is not supported yet) and core libraries (Foundation, UIKit).

React Native | A framework for building native apps with React Gesture Responder System
Gesture recognition on mobile devices is much more complicated than web. A touch can go through several phases as the app determines what the user's intention is. For example, the app needs to determine if the touch is scrolling, sliding on a widget, or tapping. This can even change during the duration of a touch. There can also be multiple simultaneous touches.
The touch responder system is needed to allow components to negotiate these touch interactions without any additional knowledge about their parent or child components. This system is implemented in
ResponderEventPlugin.js, which contains further details and documentation.Best Practices #
Users can feel huge differences in the usability of web apps vs. native, and this is one of the big causes. Every action should have the following attributes:
- Feedback/highlighting- show the user what is handling their touch, and what will happen when they release the gesture
- Cancel-ability- when making an action, the user should be able to abort it mid-touch by dragging their finger away
These features make users more comfortable while using an app, because it allows people to experiment and interact without fear of making mistakes.
TouchableHighlight and Touchable* #
The responder system can be complicated to use. So we have provided an abstract
Touchableimplementation for things that should be "tappable". This uses the responder system and allows you to easily configure tap interactions declaratively. UseTouchableHighlightanywhere where you would use a button or link on web.Responder Lifecycle #
A view can become the touch responder by implementing the correct negotiation methods. There are two methods to ask the view if it wants to become responder:
View.props.onStartShouldSetResponder: (evt) => true,- Does this view want to become responder on the start of a touch?View.props.onMoveShouldSetResponder: (evt) => true,- Called for every touch move on the View when it is not the responder: does this view want to "claim" touch responsiveness?
If the View returns true and attempts to become the responder, one of the following will happen:
View.props.onResponderGrant: (evt) => {}- The View is now responding for touch events. This is the time to highlight and show the user what is happeningView.props.onResponderReject: (evt) => {}- Something else is the responder right now and will not release it
If the view is responding, the following handlers can be called:
View.props.onResponderMove: (moveEvt) => {}- The user is moving their fingerView.props.onResponderRelease: (releaseEvt) => {}- Fired at the end of the touch, ie "touchUp"View.props.onResponderTerminationRequest: (evt) => true- Something else wants to become responder. Should this view release the responder? Returning true allows releaseView.props.onResponderTerminate: (evt) => {}- The responder has been taken from the View. Might be taken by other views after a call toonResponderTerminationRequest, or might be taken by the OS without asking (happens with control center/ notification center on iOS)
Capture ShouldSet Handlers #
onStartShouldSetResponderandonMoveShouldSetResponderare called with a bubbling pattern, where the deepest node is called first. That means that the deepest component will become responder when multiple Views return true for*ShouldSetResponderhandlers. This is desirable in most cases, because it makes sure all controls and buttons are usable.However, sometimes a parent will want to make sure that it becomes responder. This can be handled by using the capture phase. Before the responder system bubbles up from the deepest component, it will do a capture phase, firing
on*ShouldSetResponderCapture. So if a parent View wants to prevent the child from becoming responder on a touch start, it should have aonStartShouldSetResponderCapturehandler which returns true.View.props.onStartShouldSetResponderCapture: (evt) => true,View.props.onMoveShouldSetResponderCapture: (evt) => true,
