Summary:
TabBarItemIOS supports setting the scale for base64-encoded images using an optional scale parameter, however this was broken due to the JS code only passing the uri, not the whole source object, to the native side.
(See: https://github.com/facebook/react-native/issues/2413)
Summary:
We want to be able to access the touch data within our components' event handlers, so we need to thread the event object all the way through to them.
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:
The test runner relied on checking the current error message in the RCTRedbox, which is a singleton (yay, shared mutable state!). This lead to some tests that worked individually but failed when run together due to error messages in RCTRedBox left over from previous tests.
I've replaced the call to -[RCTRedBox currentErrorMessage] by injecting a custom logging function to intercept the errors at source, which is a much more reliable solution.
Summary:
There's no good reason for initialProperties to be mutable after the RCTRootView has been created. Passing it in through the constructor means we can skip one dispatch_async.
Summary:
With a multiline TextInput, the text is initially rendered correctly but once you try to edit it, the cursor slides off the top of the view and out of its bounds. Also if the TextInput is scrollable, you can scroll the text out of the bounds of the view, which looks buggy unless you clip the overflow. This occurs because the top content inset is applied to the RCTTextView instead of the UITextView's text container.
This diff fixes both bugs by applying the vertical insets to the UITextView's textContainerInset instead of the RCTTextView's frame (which is a wrapper around a real UITextView).
The left inset is still applied to the frame because there is a bug with the text rendering when the left textContainerInset is negative: the initial text doesn't show up until you focus the text view. The bug doesn't occur when setting the right textContainerInset, so I apply this workaround to only the left inset.

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:
Moved the view creation & property binding logic out of RCTUIManager into a separate RCTComponentData class - this follows the pattern used with the bridge.
I've also updated the property binding to use pre-allocated blocks for setting the values, which is more efficient than the previous system that re-contructed the selectors each time it was called. This should improve view update performance significantly.
Summary:
When mutation of a stack happens, we'd like to compute the diff of the stacks (before and after) so that
we can know which routes are removed in the new stack.
This diff adds a new method `substract` which does what we need.
Summary:
- Enables async/await in .babelrc and transformer.js
- Adds regenerator to package.json. Users still need to explicitly require the regenerator runtime -- this is so that you only pay for what you use.
- Update AsyncStorage examples in UIExplorer to use async/await
- Update promise tests in UIExplorer to use async/await in addition to the promise API

Summary:
We already reimplement the spring computation, we were only using rebound for the tension/friction conversion. Turns out that it is quite small so we can just embed it. I'm doing this as I'm preparing for doing a web version of the feature and I'm trying to minimize the number of dependencies.

Summary:
Dynamic Text Sizes for Text component.
Text gains new prop - allowFontScaling (false by default).
There is also AccessibilityManager module that allows you to tune multipliers per each content size category.
Summary:
The bridge implementation on React Android does not currently support boxed numeric/boolean types (the equivalent of NSNumber arguments on iOS), nor does Java support Objective-C's nil messaging system that transparently casts nil to zero, false, etc for primitive types.
To avoid platform incompatibilities, we now treat all primitive arguments as non-nullable rather than silently converting NSNull -> nil -> 0/false.
We also now enforce that NSNumber * objects must be explicitly marked as `nonnull` (this restriction may be lifted in future if/when Android supports boxed numbers).
Other object types are still assumed to be nullable unless specifically annotated with `nonnull`.
Summary:
Disabling the scene this way would make the scene height go to zero and mess up the scroll position. By setting the bottom to the same distance, the view does not get resized and the scroll position is preserved through a scene disable cycle.
Summary:
# Summary
Add a method `keyOf` to NavigationRouteStack.
The method `keyOf` returns a key that is associated with the route.
The a route is added to a stack, the stack creats an unique key for it and
will keep the key for the route until the route is rmeoved from the stack.
The stack also passes the keys to its derived stack (the new stack created by the
mutation API such as `push`, `pop`...etc).
The key for the route persists until the initial stack and its derived stack no longer
contains this route.
# Why Do We Need This?
Navigator has needs to use an unique key to manage the scenes rendered.
The problem is that `route` itself isn't a very reliable thing to be used as the key.
Consider this example:
```
// `scene_1` animates into the viewport.
navigator.push('scene_1');
setTimeout(() => {
// `scene_1` animates off the viewport.
navigator.pop();
}, 100);
setTimeout(() => {
// Should we bring in a new scene or bring back the one that was previously popped?
navigator.push('scene_1');
}, 200);
```
Because we currently use `route` itself as a key for the scene, we'd have to block a route
until its scene is completely off the components tree even the route itself is no longer
in the stack otherwise we'd see strange animation of jumping scenes.
# What's Next
We're hoping that we can build pure reactive view for NavigationRouteStack easily.
The naive implementation of NavigationRouteStackView may look like this:
```
class NavigationRouteStackView {
constructor() {
this.state = {
staleScenes: {},
};
}
componentWillReceiveProps(nextProps) {
if (nextProps.stack !== this.props.stack) {
var stale;
var staleScenes = {...this.state.staleScenes};
this.props.stack.forEach((route, index, key) => {
if (nextProps.stack.keyOf(route) !== key) {
stale = true;
staleScenes[key] = {route, index, key, stale};
}
});
if (stale) {
this.setState({
staleScenes,
});
}
}
}
render() {
var scenes = [];
this.props.stack.forEach((route, index, key) => {
scenes.push({route, index, key});
});
Object.keys(this.state.staleScenes).forEach(key => {
scenes.push(this.state.staleScenes[key]);
});
scenes.sort(stableSortByIndex);
return <View>{scenes.map(renderScene)}</View>;
}
}
```
Summary:
If user taps the back button quickly, the app crashes becuase "pop"
internally only checks `this.state.presentedIndex` which does not
always update when transtion happens.
This diff addresses this issue.
Summary:
Add a new bridge delegate protocol to allow a more flexible bridge configuration.
For now it just support the pre-existent configurations + providing the JavaScript
source to the bridge, that should allow pre-loading sources.
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:
In preparation for open sourcing React Native for Android, document which parts of the `CameraRoll` API are platform-specific.
Renders like this: http://imgur.com/rbpXHKf
We should improve docs generation for `@param`s.
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.
Summary:
Previously the text highlight overlay did not take padding into account in its positioning, so it would be misaligned for padded text. This fixes that.
Summary:
Hides disabled scenes using `top` instead of `left`, which fixes a bug with the native UITabBar. When the UITabBar's width is zeroed because the scene has `left: SCREEN_WIDTH, right: 0` applied, this triggers a bug with the kerning of the tab titles. Instead, zeroing the height by setting `top: SCREEN_HEIGHT` avoids the bug.
Also applies `pointerEvents="none"` to disabled scenes so that views in the off-screen scenes definitely don't receive touches, which was occurring before.

Summary:
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.
Summary:
Added the ability to turn on and off the network activity indicator using:
```
StatusBarIOS.setNetworkActivityIndicatorVisible(true)

and
```
StatusBarIOS.setNetworkActivityIndicatorVisible(false)
```
Also added an example to the UIExplorer example app.

Summary:
Animated.spring is not guarantee to stabilize at exactly toValue (determined by restDisplacementThreshold). It is a bit annoying that the last value is not toValue, it makes the logs harder to read and also prevents you from writing code like value === toValue. Instead you need to track it down somewhere else.
Summary:
Some of the examples relied on the fact that TextInput wasn't a controlled
component before. This introduces a new `initialValue` prop which behaves the
way the `value` prop used to - that is, you could type without updating it and
it wouldn't get reset, thus acting as just an initial value - and switches the
examples to use it where appropriate.
Summary:
This introduces event counts to make sure JS doesn't set out of date values on
native text inputs, which can cause dropped characters and can mess with
autocomplete, and obviates the need for the input buffering which added lag and
complexity to the component. Made sure to test simulated super-slow JS text
event processing to make sure characters aren't dropped, as well as typing
obviously correctable words and making sure autocomplete works as expected.
TextInput is now a controlled input by default without causing any issues for
most cases, so I removed the `controlled` prop.
Fixes selection state jumping by restoring it after setting new text values, so
highlighting the middle of some text in the new ReWrite example and hitting
space will replace that selection with an underscore and keep the cursor at a
sensible position as expected, instead of jumping to the end.
Ads `maxLength` prop to support the most commonly needed syncronous behavior:
preventing the user from typing too many characters. It can also be used to
prevent users from continuing to type after entering special characters by
changing it to the current length after a regex match. Made sure to verify it
works well with pasted input (including in the middle of existing text),
truncating it and collapsing the selection the same way it does on the web.
Fixes bug in TextEventsExample where it wouldn't show the submit and end events,
even though there were firing correctly.
Summary:
Re-landing D2229686 after fixing bugs mentioned in D2250586
onItemRef is old and no longer needed now that the parent renders the scenes. This removes it from Navigator and all of our clients.
This is a breaking change to users of Navigator, but it is easy to transition to a ref in renderScene instead
Summary:
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:
While adeveloper requests the emitter to emit an event, the emitter
may not emit the event immediately instead of putting the request
into a queue and process it later.
This diff allows the developer to provide a callback which will be called
when the event has been emitted.
For instance:
```
class NavigationContext {
push(nextRoute) {
var nextStack = this._stack.push(nextRoute);
this.emit(
'change',
{
reason: 'push',
nextStack: nextStack,
nextRoute: nextRoute,
},
this._onPush
);
}
_onPush(event){
if (event.defaultPrevented) {
return;
}
this._stack = event.nextStack;
this.emit('change');
}
}
```
Summary:
Because we don't want to integrate Animated inside of the core of React, we can only pass Animated.Value to styles of <Animated.View>. TouchableOpacity unfortunately used cloneElement. This means that we should have asked every single call site to replace their children to Animated.View. This isn't great.
The other solution is to stop using cloneElement and instead wrap the children inside of an <Animated.View>. This has many advantages:
- We no longer use cloneElement so we're no longer messing up with elements that are not our own.
- Refs are now working correctly for children elements
- No longer need to enforce that there's only one child and that this child is a native element
The downside is that we're introducing a <View> into the hierarchy. Sadly with CSS there is no way to have a View that doesn't affect layout. What we need to do is to remove the inner <View> and transfer all the styles to the TouchableOpacity. It is annoying but fortunately a pretty mechanical process.
I think that having a wrapper is the best solution. I will investigate to see if we can make wrappers on TouchableHighliht and TouchableWithoutFeedback as well.
**Upgrade Path:**
If the child is a View, move the style of the View to TouchableOpacity and remove the View itself.
```
<TouchableOpacity onPress={...}>
<View style={...}>
...
</View>
</TouchableOpacity>
-->
<TouchableOpacity onPress={...} style={...}>
...
</TouchableOpacity>
```
If the child is an Image or Text, on all the examples at Facebook it worked without any change. But it is a great idea to double check them anyway.
Summary:
idStack is going away soon. This removes all references to it. Looking at the internal state of navigator will make you have a bad time.
The biggest change is switching to the new component-freezing techinique in the navigation bars. This way we avoid dependence on the idStack to provide a scalar ID for each route.
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.)
