Summary: This allows the onLoad callback to know which image has actually loaded. This is only for iOS at the moment - implementing this for Android will require quite a bit more work.

Summary:

Motivation: When having a simple button that changes the Image source when tapped, the image doesn't change (or at least sometimes, intermittently it works).

This was found to be an issue where the request was being sent to the native layer correctly but then being subsequently cancelled by the `reactSetFrame: method`  ...

Gant eba6c379c3 - Update remote image example
Summary:
I've seen quite a few newbs trip on this, so I'm fixing it.

First - you have to set the width/height on a remote image, otherwise nothing shows.  This is [even on stack overflow](http://stackoverflow.com/questions/30091398/unable-to-display-image-with-react-native-with-uri).

Second - with the addition of ATS in iOS most people who copy/paste this example will not be able to load an insecure image, so I changed it to the `https`.

**RESULT** this doc becomes copy/paste friendly again for beginners.

skatpgusskat 631785f2ee Change RCTImageLoader's Cache System to default NSURLRequest's cache system
Summary:
Before this PR, ```RCTImageLodaer```'s Cache was too big(200MB on disk) and It doesn't work with HTTP Cache-Control header. So to provide dynamic image, the users must have to add random value on url( ex. adding current date) to avoid cache.

So I change that cache system to default ```NSURLRequest```'s cache system, which is well-working with HTTP specs. As the discussion on this issue #7571 , making custom cache policy processor is not ready yet and useless, over-tech things, I think.

Even we have no plan about image cache system(or would change plan later), before having a nice plan, I think we should let user use image module with common HTTP Specs.

So I remove custom ```NSURLCache```, and make logic like below,

1. try fetch image,

2. on response, get ```Date``` on response's header and make ```cacheKey``` with ```Date```.
> (why? because if ```NSURLRequest```'s response was cached, the response's ```Date``` header dosen't change.)

3. find decoded imag

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

aleclarsoniv bee118096b Add Image resizeMode center to iOS
Summary:
Addresses this comment: https://github.com/facebook/react-native/issues/2296#issuecomment-232446493

This pull request adds the `center` value to `ImageResizeMode`.
When set, it will center the image within its frame.
If the image is larger than its frame, the image is downscaled while maintaining its aspect ratio.
That is how the Android implementation works, too.

Sorry, don't have time to write tests. 😢

Any reviewers should make sure `RCTTargetRect` returns the correct value when:
- the image is smaller than its frame (ie: no downscaling needed)
- the image is larger than its frame (should be downscaled to avoid clipping)

Jean Regisser 7f9ec4e4c8 Fixed incorrect style props passed to Android Image when using children
Summary:
Hi there,

Here is a fix for #7538 (and #5085).

I had originally discovered this issue when using `resizeMode` through the style props. Although this might arguably be an incorrect usage (see https://github.com/facebook/react-native/issues/4759#issuecomment-164301166) the same issue would happen with the `tintColor` and `overlayColor` style props.

To  test this, you can render the following:

```jsx
const imageContainerStyle = {width: 100, height: 100, backgroundColor: 'green', marginLeft: 10, marginTop: 10, };
const imageStyle = {flex: 1, width: undefined, height: undefined, resizeMode: 'contain', };

return (
  <View style={styles.container}>
    <View style={imageContainerStyle}>
      <Image style={imageStyle} source={
        {uri:'http://resizing.flixster.com/DeLpPTAwX3O2LszOpeaMHjbzuAw=/53x77/dkpu1ddg7pbsk.cloudfront.net/movie/11/16/47/11164719_ori.jpg'}

Janic Duplessis 4c83237511 Add Image resizeMode repeat on iOS
Summary:
This adds a new resize mode for iOS 'repeat' that tiles the image over it's frame. This allow to easily create a view with a repeating background pattern which there is no way to do at the moment without including a bunch of different sized assets.

I'm not 100% sure it should be a resizeMode or a separate prop but I went with resizeMode since it made more sense to me and the are not really any use cases where we'd want to use this with another resizeMode other than 'stretch'.

**Test plan**

Tested mainly by adding a UIExplorer example, also tested that changing the resizeMode prop from and to 'repeat' worked properly.

Andrei Coman 617a38d984 Support multi sources for images
Summary:
This adds support for specifying multiple sources for an image component, so that native can choose the best one based on the flexbox-computed size of the image.
The API is as follows: the image component receives in the `source` prop an array of objects of the type `{uri, width, height}`. On the native side, the native component will wait for the layout pass to receive the width and height of the image, and then parse the array to find the best fitting one. For now, this does not support local resources, but it will be added soon.
To see how this works and play with it, there's an example called `MultipleSourcesExample` under `ImageExample` In UIExplorer.

Nick Lockwood 235749ba19 Fix missing images
Summary:
Under rare and as-yet-to-be determined circumstances, images can sometimes fail to load/download and get "stuck", without producing an error.

Because the `RCTNetworkTask` for these images is stuck in the "in progress" state, they clog up the RCTImageLoader task queue, which has a limit of 4 concurrent in-progress tasks.

This was previously masked by the fact that we automatically cancelled image requests when the RCTImageView moved offscreen, but we no longer do that.

This diff adds logic to detect some types of stuck task and remove them, thereby unblocking the queue. I've also restored the functionality of cancelling downloads for offscreen images (but not unloading the image itself) so that stuck images will be cancelled when you move to another screen, instead of using up space in the queue forever.

As you can see the domain name is missing from the URL. I traced it back to a method which handles redirects. It would retrieve the redirect URL from the `Location` header field, but it didn’t handle the case where `Location` contains a relative URL (which [according to the RFC spec](https://tools.ietf.org/html/rfc7231#section-7.1.2), is allowed).

As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.

This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.

I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Adam Comella ee8496f364 iOS: Support HTTP headers for source prop on <Image> components
Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:

```
<Image
  style={styles.logo}
  source={{
    uri: 'http://facebook.github.io/react/img/logo_og.png',
    headers: {
      Authorization: 'someAuthToken'
    }
  }}
/>
```

Note that the header values must be strings.

Works on iOS and Android.

**Test plan (required)**

- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.

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 b49633e020 Fixed image test flakiness by tying decoded image cache to module lifecycle
Summary: The decoded image cache was previously static, meaning that cached images could persist beyond the lifetime of the module. This resulted in some flakiness in the RCTImageLoaderTests due to the loader returning cached image instanced from previous tests instead of the correct instance.

Ben Nham 71bf8a3e48 Only clear image contents on memory warning
Summary:
Some apps are complaining about flashing images when performing navigation transitions. An example issue would be:

1. Load a master list view with many images
2. Click on an image to go to a detail view
3. Go back to the master list view

At step (3), users see a number of images flash from a placeholder image back to the final image because `-[RCTImageView didMoveToWindow]` calls `clearImage` when the image view exits the view hierarchy between (1) and (2) and calls `reloadImage` (which sets the image property asynchronously) when the image view re-enters the view hiearchy between (2) and (3).

This diff fixes the issue by being less aggressive about clearing image contents. It only clears image contents when the app receives a memory warning or the app goes into the background.

For comparison, CKNetworkImageComponent in ComponentKit doesn't have this purging behavior at all.

Nick Lockwood c8f39c3d2c Added small decoded image cache to prevent images flashing when component is reloaded
Summary:
In RN we cache image data after loading/downloading an image, however the data we store is the compressed image data, and we decode this asynchronously each time it is displayed.

This can lead to a slight flicker when reloading image components because the decoded image is discarded and then re-decoded.

This diff adds a small (5MB) cache for decoded images so that images that are currently on screen shouldn't flicker any more if the component is reloaded.
