Summary: - When a key is pressed, it's `key value` is passed as an argument to the callback handler. - For `Enter` and `Backspace` keys, I'm using their `key value` as defined [here](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key#Key_values). As per JonasJonny & brentvatne's [suggestion](https://github.com/facebook/react-native/issues/1882#issuecomment-123485883). - Example ```javascript _handleKeyPress: function(e) { console.log(e.nativeEvent.key); }, render: function() { return ( <View style={styles.container}> <TextInput style={{width: 150, height: 25, borderWidth: 0.5}} onKeyPress={this._handleKeyPress} /> <TextInput style={{width: 150, height: 100, borderWidth: 0.5}} onKeyPress={this._handleKeyPress} multiline={true} /> </View> ); } ``` - Implements [shouldChangeCharactersInRange](https://developer.apple.com/library/prerelease/ios/documentat Closes https://github.com/facebook/react-native/pull/2082 Reviewed By: javache Differential Revision: D2280460 Pulled By: nicklockwood fb-gh-sync-id: 1f824f80649043dc2520c089e2531d428d799405
UIExplorer
The UIExplorer is a sample app that showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
cd react-native
npm install
Running on iOS
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeproj
in Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer app in your emulator.
See Running on Device in case you want to use a physical device.
Built from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init
which have a dependency on a specific version of React Native JS and native code, declared in a package.json
file (and build.gradle
for Android apps).
