Janic Duplessis 5903949ad6 Load local assets synchronously to prevent image flicker
Summary:
This uses `[UIImage imageNamed:]` to load local assets that are bundled using `require('../image/path.png')` and makes sure it is done synchronously on the main queue to prevent images from flickering. This improves user experience a lot when using large local images and prevents icon flickers to match the behaviour of most native apps.

This adds to methods to the ImageLoader protocol, one to tell if the image loader must be executed on the url cache queue and one to tell if the result of the image loader should be cached. I then use these to make the LocalImageLoader bypass the url cache queue and avoid caching images twice.

Note that this doesn't affect debug builds since images are loaded from the packager.

I'm not sure if we want to still support async loading of local images as I'm not sure how much of a perf difference this will make. Maybe someone at fb can benchmark this see how it affects your apps but there wasn't a noticeable one in mine. Also I only enabled this for loading png and jpg im

Adam Comella 486dbe4e8f 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

Nick Lockwood 1076f4a172 Added RCTDataRequestHandler
Summary: public

Added RCTDataRequestHandler, which is responsible for loading data URLs. This moves the logic for data URL handling out of RCTImageDownloader (no longer needed) and into the RCTNetwork library, where it makes more sense.

This also means that it is now possible to load data URLs via XHR, and use them for purposes other than just images.

Nick Lockwood 799168929c Unify XCAsset handling logic
Summary: @​public

This diff unifies the logic for detecting when images refer to XCAsset files into a single function (RCTXCAssetNameForURL) and uses it for both +[RCTConvert UIImage:] and RCTImageLoader.

I've also tightened the definition of XCAssets so that it only applies to images inside .car files, not any image inside the main bundle. This avoids using the +[UIImage imageNamed:] when not strictly necessary, which is desirable since that method is not thread-safe, and has undocumented caching behavior that is difficult to reason about.

Summary: @​public

This diff implements inline image support for <Text> nodes. Images are specified using <Image> tags, however all properties of the image are currently ignored apart from the source (including width/height styles).

Images are loaded asyncronously, and will trigger a text re-layout when they have loaded.

Nick Lockwood 56d25bbbdd Moved CameraRoll-related classes into CameraRoll folder instead of Image
Summary:
The CameraRoll-related APIs were mixed in with the Image classes due to legacy coupling issues. Now that the APIs have been decoupled, it makes more sense for the CameraRoll classes to live in a separate library.

This will be a breaking change for apps using the CameraRoll or related APIs. Fix is to add the RCTCameraRoll lib to your project.

Nick Lockwood 61c648d564 Merged RCTNetworkImageView functionality into RCTStaticImage
Summary:
RCTNetworkImageView and RCTStaticImage had significant overlap in functionality, but each had a different subset of features and bugs.

This diff merges most of the functionality of RCTNetworkImageView into RCTStaticImage, eliminating some bugs in the former, such as constant redrawing when properties were changed.

I've also removed the onLoadAbort event for now (as it wasn't implemented), and renamed the other events to match the web specs for `<img>` and XHMLHttpRequest. The API is essentially what Adobe proposed here: http://blogs.adobe.com/webplatform/2012/01/13/html5-image-progress-events/

The following features have not yet been ported from RCTNetworkImageView:

- Background color compositing. It's not clear that this adds much value and it increases memory consumption, etc.
- Image request cancelling when images are removed from view. Again, it's not clear if this is a huge benefit, but if it is it should be combined with other optimisations, such as unloading offscreen images.

(Note that this only affects the open source fork. For now, internal apps will still use FBNetworkImageView for remote images.)

Dmitriy Loktev 8e70c7f003 [Image] Add onLoadStart, onLoadProgress, onLoadError events to Image component
Summary:
This PR adds 4 native events to NetworkImage.

![demo](http://zippy.gfycat.com/MelodicLawfulCaecilian.gif)

Using these events I could wrap `Image` component into something like:
```javascript
class NetworkImage extends React.Component {
  getInitialState() {
    return {
      downloading: false,
      progress: 0
    }
  }

  render() {
    var loader = this.state.downloading ?
      <View style={this.props.loaderStyles}>
        <ActivityIndicatorIOS animating={true} size={'large'} />
        <Text style={{color: '#bbb'}}>{this.state.progress}%</Text>
      </View>
      :
      null;

    return <Image source={this.props.source}
      onLoadStart={() => this.setState({downloading: true}) }
      onLoaded={() => this.setState({downloading: false}) }
      onLoadProgress={(e)=> this.setState({progress: Math.round(100 * e.nativeEvent.written / e.nativeEvent.total)});
      onLoadError={(e)=> {
        alert('the image cannot be downloaded because: ', JSON.stringify(e));
        this.setState({downloading: false});
      }}>
      {loader}
    </Image>
  }
}
```
Useful on slow connections and server errors.

There are dozen lines of Objective C, which I don't have experience with. There are neither specific tests nor documentation yet. And I do realize that you're already working right now on better `<Image/>` (pipeline, new asset management, etc.). So this is basically a proof concept of events for images, and if this idea is not completely wrong I could improve it or help somehow.

Nick Lockwood f88bc3eb73 [ReactNative] Refactor RCTDataManager to support pluggable data source modules (RCTURLRequestHandlers)
Summary:
@public

This is a refactor of @philikon's original diff that decouples the dependencies between the Network and Image modules, and replaces RCTDataQueryExecutor with a more useful abstraction.

I've introduced the RCTURLRequestHandler protocol, which is a new type of bridge module used for loading data using an NSURLRequest. RCTURLRequestHandlers can be registered using RCT_EXPORT_MODULE() and are then available at runtime for use by the RCTDataManager, which will automatically select the appropriate handler for a given request based on the handler's self-reported capabilities.

The currently implemented handlers are:

- RCTHTTPRequestHandler - the standard open source HTTP request handler that uses NSURLSession
- RKHTTPRequestHandler - the internal FB HTTP request handler that uses FBNetworking
- RCTImageRequestHandler - a handler for loading local images from the iOS asset-library

Depends on D2108193

Test Plan:
- Internal apps still work
- OSS port still compiles, Movies app and a sample Parse app still work
- uploading image to Parse using the above code snippet works
- tested `FormData` with string and image parameters using http://www.posttestserver.com/
