Summary:
public
React Native currently exposes the iOS layer shadow properties more-or-less directly, however there are a number of problems with this:
1) Performance when using these properties is poor by default. That's because iOS calculates the shadow by getting the exact pixel mask of the view, including any tranlucent content, and all of its subviews, which is very CPU and GPU-intensive.
2) The iOS shadow properties do not match the syntax or semantics of the CSS box-shadow standard, and are unlikely to be possible to implement on Android.
3) We don't expose the `layer.shadowPath` property, which is crucial to getting good performance out of layer shadows.
This diff solves problem number 1) by implementing a default `shadowPath` that matches the view border for views with an opaque background. This improves the performance of shadows by optimizing for the common usage case. I've also reinstated background color propagation for views which have shadow props - this should help ensure that this best-case scenario occurs more often.
For views with an explicit transparent background, the shadow will continue to work as it did before ( `shadowPath` will be left unset, and the shadow will be derived exactly from the pixels of the view and its subviews). This is the worst-case path for performance, however, so you should avoid it unless absolutely necessary. **Support for this may be disabled by default in future, or dropped altogether.**
For translucent images, it is suggested that you bake the shadow into the image itself, or use another mechanism to pre-generate the shadow. For text shadows, you should use the textShadow properties, which work cross-platform and have much better performance.
Problem number 2) will be solved in a future diff, possibly by renaming the iOS shadowXXX properties to boxShadowXXX, and changing the syntax and semantics to match the CSS standards.
Problem number 3) is now mostly moot, since we generate the shadowPath automatically. In future, we may provide an iOS-specific prop to set the path explicitly if there's a demand for more precise control of the shadow.

Summary:

This diff adds a `getSize()` method to `Image` to retrieve the width and height of an image prior to displaying it. This is useful when working with images from uncontrolled sources, and has been a much-requested feature.
In order to retrieve the image dimensions, the image may first need to be loaded or downloaded, after which it will be cached. This means that in principle you could use this method to preload images, however it is not optimized for that purpose, and may in future be implemented in a way that does not fully load/download the image data.
A fully supported way to preload images will be provided in a future diff.
The API (separate success and failure callbacks) is far from ideal, but until we agree on a unified standard, this was the most conventional way I could think of to implement it. If it returned a promise or something similar, it would be unique among all such APIS in the framework.
Please note that this has been a long time coming, in part due to much bikeshedding about what the API should look like, so while it's not unlikely that the API may change in future, I think having *some* way to do this is better than waiting until we can define the "perfect" way.

The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.
This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.

Summary: public
The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.
This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.
The rules are now as follows:
* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.
These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.
I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:
Out of the 65 modules included in UIExplorer:
* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand

I'm currently building an app that changes metadata, does some resizes, maybe watermarking ...etc. I want to use RCTImageStoreManager to store the original image in memory and allow me to command different modifications from javascript as it gives me more flexibility.

So i suggest we change it to NSData.

The idea is to always load images from the same folder that we loaded JS bundle.
This doesn't change the current behavior, since `imageNamed:` inferred the
absolute path to the image from app's bundle, but now we make it explicit.
The benefit for OTA updates implementations is that they can simply ask RN
to load js from some `~/Documents/<build-id>/main.jsbundle` folder and RN will
look for images in `~/Documents/<build-id>/assets/`.
Note that for Android we will have to come out with a different plan, since
in prod we load images from built-in resources.

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.

Summary:
GIF images are currently loaded as a CAKeyframeAnimation, however returning this animation directly from RCTImageLoader was dangerous, as any code that expected a UIImage would crash.
This diff changes RCTGIFImageLoader to return a UIImage of the first frame, with the keyframe animation attached as an associated object. This way, code that is not expecting an animation will still work correctly.
Summary:
Currently, the system for mapping JS event handlers to blocks is quite clean on the JS side, but is clunky on the native side. The event property is passed as a boolean, which can then be checked by the native side, and if true, the native side is supposed to send an event via the event dispatcher.
This diff adds the facility to declare the property as a block instead. This means that the event side can simply call the block, and it will automatically send the event. Because the blocks for bubbling and direct events are named differently, we can also use this to generate the event registration data and get rid of the arrays of event names.
The name of the event is inferred from the property name, which means that the property for an event called "load" must be called `onLoad` or the mapping won't work. This can be optionally remapped to a different property name on the view itself if necessary, e.g.
RCT_REMAP_VIEW_PROPERTY(onLoad, loadEventBlock, RCTDirectEventBlock)
If you don't want to use this mechanism then for now it is still possible to declare the property as a BOOL instead and use the old mechanism (this approach is now deprecated however, and may eventually be removed altogether).
Summary:
require('./image.jpg') returns a number and therefore the propType is wrong. Adding it to the propType to fix the warning and dealing with flow which is completely broken for this.
Summary:
Our events all follow a common pattern, so there's no good reason why the configuration should be so verbose. This diff eliminates that redundancy, and gives us the freedom to simplify the underlying mechanism in future without further churning the call sites.
Summary:
Addresses #1534
When an image has a known width, but a height of 0 (which can happen if `flex: 1` is set on the `Image` element), `RCTDownloadManager` attempts to scale it to an invalid size, which results in a `NULL` `CGContextRef` and some scary warnings from UIKit:
```
<Error>: CGContextTranslateCTM: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.
```
This adds a check for zero width or height to the `RCTClipRect` function. If either dimension is zero, it is calculated based on the aspect ratio of the source image. This ensures that we don't try to create an invalid `CGContextRef`, and that images with an unknown dimension are still scaled, blended, etc.

Summary:
For some reason we're now spamming the logs everytime we render an Image because overflow is not defined in the whitelist. overflow: 'hidden' is needed for network images with cover mode.
The way we currently define those is not optimal where we try to factor as many things as possible into distinct propTypes. However for Text we're not even using this but we are getting all the ones from View (which many do not apply) and remove some that aren't needed.
It may be useful to cleanup this in the future but in the short term, it's better to remove this warning that doesn't have much value anyway.
Summary:
This is a quick fix for the RCTDownloadTaskWrapper crashing on iOS 7. The issue was that the object returned by -[NSURLSession downloadTaskWithURL:] on iOS was not actually a subclass of NSURLSessionTask, so the category that adds associated blocks was not working. I've fixed that by making it a category on NSObject instead.

This diff implements highlighting of tapped text subranges for the iOS `<Text>` component, styled to match how iOS webkit views highlight links (translucent grey overlay with rounded corners).
Highlighting is enabled by default for any `<Text>` component which has an onPress handler. To disable the highlight, add `suppressHighlighting={true}` to the component props.

Update to https://github.com/facebook/react-native/pull/1969
--
Recent improvements allow RCTImageLoader to select a more appropriate sized image based on the layout dimensions. Sizes:
- asset.thumbnail
- asset.aspectRatioThumbnail
- asset.defaultRepresentation.fullScreenImage
- asset.defaultRepresentation.fullResolutionImage
Prior, only the fullResolutionImage was used. This was memory intensive and resulted in crashes when loading several large images at once. The updated implementation works well, but can be made more efficient:
Consider loading 10 8MP (3264x2448) images in 150x150 pixel containers. The target size (150x150) is larger than asset.thumbnail (approx 100x100), therefore the fullScreenImage representation is used instead (approx 1334x1000).
This commit will scale the asset to the minimum size required while taking into account original aspect ratio and device scale. Memory usage is considerably lower and many more images can be loaded in
sequence without having to worry

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.)
Summary:
RCTImageDownloader was ignoring server response codes. When receiving a response other than 200 it would treat this as success, meaning the image would never load, nor report failure.
This diff fixes that by treating responses with non-200 status as an error so that error handler is called.
Summary:
Merged RCTStaticImage with our internal RKStaticImage and ported over logic where assets are loaded at the optimal size and reloaded if the view size changes.
Summary:
Remote images now support the `tintColor` prop.
Also picked nicer demo colors for the UIExplorer example.

Summary:
Change `RCTImageDownloader` so it stores the `RCTDownloadTaskWrapper` for reuse. Modify `RCTDownloadTaskWrapper` to use associated objects to store the completion/progress blocks.
Summary:
This PR adds 4 native events to NetworkImage.
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.

Summary:
This introduces a new `RCTResponseErrorBlock` block type that allows a bridge module writer to call it with an `NSError` instance rather than a dictionary.
Summary:
If you try to create a cached response from a nil response the app will crash. Looking at the code that uses NSURLSession and NSURLCache, this fix looks correct to me.

Summary:
resizeMode is a native prop, but it is also in the propTypes, so this causes an incorrect warning:
```
Prop resizeMode = `contain` should not be set directly on Image.

Test Plan: No warnings on image example in UIExplorer
Summary:
This PR adds support for UIImagePickerController to allow selecting a photo / video from the users camera roll.
Example:
Selecting something from camera roll
```
ImagePickerIOS.openSelectDialog(<config>, <successCallback>, <cancelCallback>);
ImagePickerIOS.openSelectDialog({
showImages: true, // defaults to true
showVideos: false // defaults to false
}, function (data) {
console.info("Got a callback!");
console.info(data); // file URL as in assets-library://asset/asset.JPG?id=E2741A73-D185-44B6-A2E6-2D55F69CD088&ext=JPG
}, function() {
console.info("Cancelled");
});
```
Using camera
```
ImagePickerIOS.openCameraDialog(<config>, <successCallback>, <cancelCallback>);
ImagePickerIOS.openSelectDialog({
videoMode: false, // defaults to true, whether to record videos instead
}, function (data) {
console.info("Got

I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.
Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.

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/
Summary:
This adds a parameter for fetching videos from the camera roll. It also changes the default to fetch both videos and photos.

Summary:
With this in place, it's possible to upload a picture from the `CameraRoll` to Parse, for instance:
xhr = new XMLHttpRequest();
xhr.onload = function() {
data = JSON.parse(xhr.responseText);
var parseFile = new Parse.File(data.name);
parseFile._url = data.url;
callback(parseFile);
};
xhr.setRequestHeader('X-Parse-Application-Id', appID);
xhr.setRequestHeader('X-Parse-JavaScript-Key', appKey);
xhr.open('POST', 'https://api.parse.com/1/files/image.jpg');
// assetURI as provided e.g. by the CameraRoll API
xhr.send(new NativeFile(assetURI));

Summary:

Our background color propagation mechanism is designed to make rendering of translucent content more efficient by pre-blending against an opaque background. Currently this only works for text however, because images are not composited into their background even if the background color is opaque.
This diff precomposites network images with their background color when the background is opaque, allowing them to take advantage of this performance optimization.
I've also added some logic to correctly crop the downloaded image when the resizeMode is "cover" or "contain" - previously it was only correct for "stretch".
Before:{F22437859}
After:{F22437862}
Test Plan: Run the UIExplorer "<ListView> - Paging" example with "color blended layers" enabled and observe that the images appear in green now, instead of red as they did before.
Summary:
ActivityIndicator was forwarding all of its props except `style` to the inner native view. This meant that onLayout would report a zero-sized frame that was relative to the wrapper view instead of the parent of the ActivityIndicator.
This diff adds `onLayout` to the wrapper view instead of the native view.
In general, all components that forward props need to be audited in this manner.
Closes https://github.com/facebook/react-native/pull/1292
Github Author: James Ide <ide@jameside.com>
Test Plan: `<ActivityIndicator onLayout={...} />` reports the size of the spinner plus a position relative to its parent view.
Summary:
@vjeux and I were discussing this in irc an discovered that network gif images did not respond how they should to width, height or flex properties. Along the way I also noticed that the scale was not changing depending on the device. This PR fixes that, so now you can do `flex: 1` on a gif image to have it stretch to the whole screen. [Minimum reproducible example here](https://gist.github.com/brentvatne/f745377b0789162a28df) - try this without and then with the changes of this PR to see.

Summary:
This is a fix for #322
When setting a new image via the imageURL property, the new image
doesn't always replace the previous one when it is finished downloading
because the image view has a previously instated layer animation
on its contents. This cancels any animation prior to setting the new
contents to fix the issue.
