Summary: Adds the feature to use percentage as a value unit. You can use the function ```YGPx(float)``` and ```YGPercent(float)``` for convenience. I did some benchmarks: ``` Without Percentage Feature - Release x86: Stack with flex: median: 0.000000 ms, stddev: 0.146683 ms Align stretch in undefined axis: median: 0.000000 ms, stddev: 0.136525 ms Nested flex: median: 0.000000 ms, stddev: 0.490101 ms Huge nested layout: median: 23.000000 ms, stddev: 0.928291 ms Stack with flex: median: 0.000000 ms, stddev: 0.170587 ms Align stretch in undefined axis: median: 0.000000 ms, stddev: 0.143384 ms Nested flex: median: 0.000000 ms, stddev: 0.477791 ms Huge nested layout: median: 22.000000 ms, stddev: 2.129779 ms With Percentage Feature - Release x86: Stack with flex: median: 0.000000 ms, stddev: 0.132951 ms Align stretch in undefined axis: median: 0.000000 ms, stddev: 0.136525 ms Nested flex: median: 0.000000 ms, stddev: 0.489570 ms Huge nested layout: median: 21.000000 ms, stddev: 1.390476 ms Closes https://github.com/facebook/yoga/pull/258 Reviewed By: dshahidehpour Differential Revision: D4361945 Pulled By: emilsjolander fbshipit-source-id: a8f5bc63ad352eb9410d792729e56664468cd76a
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:
git clone https://github.com/facebook/react-native.git
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.
Running with Buck
Follow the same setup as running with gradle.
Install Buck from here.
Run the following commands from the react-native folder:
./gradlew :ReactAndroid:packageReactNdkLibsForBuck
buck fetch uiexplorer
buck install -r uiexplorer
./packager/packager.sh
Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).
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).
