Adam Comella fe5c0d2d06 iOS: Enable views to be nested within <Text> 
Summary:
Previously, only Text and Image could be nested within Text. Now, any
view can be nested within Text. One restriction of this feature is
that developers must give inline views a width and a height via
the style prop.

Previously, inline Images were supported by using iOS's built-in support
for rendering images with an NSAttributedString via NSTextAttachment.
However, NSAttributedString doesn't support rendering arbitrary views.

This change adds support for nesting views within Text by creating one
NSTextAttachment per inline view. The NSTextAttachments act as placeholders.
They are set to be the size of the corresponding view. After the text is
laid out, we query the text system to find out where it has positioned each
NSTextAttachment. We then position the views to be at those locations.

This commit also contains a change in `RCTShadowText.m`
`_setParagraphStyleOnAttributedString:heightOfTallestSubview:`. It now only sets
`lineHeight`, `textAlign`, and `writingDirection` when they've actua
Closes https://github.com/facebook/react-native/pull/7304

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).
