Summary:
RCTShadowText currently explicitly defaults to black text color:
https://github.com/facebook/react-native/blob/d46ac11/Libraries/Text/RCTShadowText.m#L204
However, the UITextView used by RCTTextInput doesn't explicitly default to black text color.
This causes issues when RCTTextInput is in rich text editing mode (i.e. when the <TextInput> element uses child <Text> nodes to provide extra styling info) and the client doesn't provide us with any explicit color info. In this case, the following series of badness occurs:
1. -[UITextView attributedText] will return an attributed string without the NSColor property set.
2. -[RCTShadowText attributedString] will return an attributed string with NSColor equal to blackColor.
3. The `[_textView.attributedText isEqualToAttributedString:_pendingAttributedText]` check in -performPendingTextUpdate will fail and causes -[UITextView setText:] to be called.
4. -setText: clears the marked text range in the text view, which breaks multi-character autocomplete (e.g. QWERTY input methods for CJK languages).
The easiest fix for now is to just make sure RCTUITextView and RCTShadowText default to the same text color.

Summary:
The TextInput when configured with `multiline=true` has a minor issue due to which if the initial text doesn't fit in one line, the input won't span multiple lines. The root cause of the problem is that the `onChange` event is not fired for the initial render. This issue has been reported on open-source: 481f560f64
This is an attempt to fix this problem by moving the logic to fire the event to the method that updates the content size. This way we can guarantee that anytime the content size changes we'll trigger the JS event.
The downside of this approach is that it's possible that multiple events get fired for a single character change. As per the comment that was removed, this was already happening when adding a character that when rendered, would increase the content size. By moving the code to the new place, this can happen more often (twice per character tapped). Let me know if you think this is an issue.

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`

Summary:This fixes autocomplete for CJK text input by making sure that the `<Text>` nodes that JS controls to produce attributed text matches the text view's attributed text as much as possible. This is done by giving the disconnected `<Text>` child the same style as the `<TextInput>` parent.
This works because `-[RKTextView performPendingTextUpdate]` avoids setting the attributedText property on textView if the JS attributedText and textView attributedText are equal. This is important because setting attributedText on a text view clears the autocomplete state (markedText property) on a text view, breaking autocomplete for multistage input styles like CJK with a phonetic keyboard.

Summary:The default value for fontSizeMultiplier was zero. Although this was usually overriden with the correct value (typically 1.0), it sometimes wasn't resulting in a divide-by-zero in the text height calculation.
This diff corrects that bug by setting 1.0 as the default, and guarding against zero values being set.
I also fixed some suspicious logic that seemed to assume the result of BOOL && CGFloat would be 0 or the CGFloat value, which is true in JS but not in C (it would always be 0 or 1).

Different touchable types are color-coded differently.
If there is `hitSlop`, it will be rendered with an extra view with a dashed border of the same color (not visible on
Android because `overflow: 'hidden'`).
`Text` with `onPress` directly set is just colored.
Added some extra checks to `TouchableWithoutFeedback` since it could silently break if the child is not a native
component.
Also added better error output for `ensureComponentIsNative` so it's easier to track down issues. I really wish there
was a cleaner way to get the component and owner names consistently, it would help make good debug messages way easier

Summary:**Motivation**
Multiple instances of `Text` inside a `ListView` is a bad idea for the performance of the app.
When you create 1000 elements and you scroll through the list it is really slow and laggy because the `NSTextStorage`, which is the backbone of the `RCTText` element, will set more than 1,000 times and also the method `setNeedsDisplay` is called multiple times. This will causes huge memory problems and the app crashes.
With this commit I check in `RCTText` if the `NSTextStorage` differs from the old value. If yes then set it otherwise don't set the `NSTextStorage`. This will prevent to call `setNeedsDisplay` when not really needed.

This diff adds support for auto-resizing multiline text fields. This has been a long-requested feature, with several native solutions having been proposed (see https://github.com/facebook/react-native/pull/1229 and D2846915).
Rather than making this a feature of the native component, this diff simply exposes some extra information in the `onChange` event that makes it easy to implement this in pure JS code. I think this is preferable, since it's simpler, works cross-platform, and avoids any controversy about what the API should look like, or how the props should be named. It also makes it easier to implement custom min/max-height logic.

Summary:

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:
public
Blending semitransparent pixels against their background is fairly a fairly expensive operation on mobile GPUs. To reduce blending, React Native has a system called "background color propagation", where the background color of parent views is automatically inherited by child views unless explicitly overridden. This means that translucent pixels can be blended directly against a known background color, avoiding the need to do this dynamically on the GPU.
In practice, this is only useful for views that do their own drawing, which is basically just `<Image/>` and `<Text/>` components, and for image components it only really matters when the image has an alpha component.
The automatic background propagation is a bit of a hack, and often does the wrong thing - for example if a view overflows its bounds, or if it overlaps a sibling, the background color will often be incorrect and need to be manually disabled. Because the only place that it provides a significant performance benefit is for text, this diff disables the behavior for everything except `<Text/>` nodes. It might still be useful for `<Image/>` nodes too, but looking through the examples in UIExplorer, the number of places where it does the wrong thing for images outnumbers the cases where it provides significant reduction in blending.
Note that this diff does not prevent you from eliminating blending on image components by manually setting an opaque background color, nor does it stop you from disabling color propagation on text components by manually setting a transparent background.

This diff makes the binding lazy, so that the main handlers are only bound if there is a valid touch action configured (e.g. onPress), and the Touchable mixin functions are only bound the first time the node is actually touched and becomes the responder.

Summary: There is no point in returning empty block here. It's a tiny bit wasteful and prevents us from knowing if there are any UI updates.
Depends on D2571122 (not really).

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.

Summary:
Now that UITextViews have a delegate, they consume the "tap to scroll to top" gesture. This diff restores the original behavior of letting the top-level scroll view (if any) scroll to top instead.
I tried exposing scrollsToTop as a prop and was semi-successful in that I could turn scroll-to-top on and off for the top-level scroll view scroll, but the text view itself would never scroll to top. So instead of exposing it as a prop, this diff sets scrollsToTop always to NO, which is how TextInput behaved previously.

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:
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:
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:
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:
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:
Dynamic Text Sizes for Text component.
Text gains new prop - allowFontScaling (true by default).
There is also AccessibilityManager module that allows you to tune multipliers per each content size category, but predefined multipliers are there.
This could potentially break some apps so please test carefully.

Summary:
Remove layout-only views. Works by checking properties against a list of known properties that only affect layout. The `RCTShadowView` hierarchy still has a 1:1 correlation with the JS nodes.
This works by adjusting the tags and indices in `manageChildren`. For example, if JS told us to insert tag 1 at index 0 and tag 1 is layout-only with children whose tags are 2 and 3, we adjust it so we insert tags 2 and 3 at indices 0 and 1. This keeps changes out of `RCTView` and `RCTScrollView`. In order to simplify this logic, view moves are now processed as view removals followed by additions. A move from index 0 to 1 is recorded as a removal of view at indices 0 and 1 and an insertion of tags 1 and 2 at indices 0 and 1. Of course, the remaining indices have to be offset to take account for this.
The `collapsible` attribute is a bit of a hack to force `RCTScrollView` to always have one child. This was easier than rethinking out the logic there, but we could change this later.

Test Plan: There are tests in `RCTUIManagerTests.m` that test the tag- and index-manipulation logic works. There are various scenarios including add-only, remove-only, and move. In addition, two scenario tests verify that the optimization works by checking the number of views and shadow views after various situations happen.
Summary:

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.
Summary:

setFrame:forRootView: wasn't triggering a batch update, which is required to trigger text update. This meant text wasn't re-displayed after a rotate, only after a touch.
I also found a bug that meant we weren't caching textStorage as much as we could be. Fixed that too.
Test Plan:
* Test <Text> example in UIExplorer and ensure it lays out on rotate.
* Test <Timers> example and verify text is still updating
* Products shouldn't be affected as they have separate text implementation

This fixes an issue with the containerBackgroundColor property of `<Text>` nodes, where containerBackgroundColor was being overridden by the backgroundColor. I also fixed up the example so that it demonstrates the feature more clearly.

* Check UIExplorer text example
* Run Catalyst snapshot tests and check MAdMan, Groups
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:
Some of the RCTTextView properties weren't set up correctly which would cause bugs when you'd set a property and then unset it, trying to revert to the default. This requires reading the default value from the dummy view instance, but some of these properties didn't have getters which was causing issues.
Fixes#1174

{D1953613} added an optimization that allowed for shadow nodes that are not
backed by views, but didn't actually work robustly in the remove case because
the indices can get out of sync. That diff also started returning nil for raw
text nodes, which triggered this bug and broke "see more" functionality in the
`FBTextWithEntities` and `ExpandingText` components, leading to crashes in the
Groups app.
This diff fixes the issue by simply returning `UIView` placeholders again.
Slight perf/ memory cost but no more crashes and there should be no other
adverse affects.
We'll need to think up something more clever in order to properly support `nil`
views in the future, probably something that uses the shadow hierarchy to build
the View hierarchy, rather than mirroring identical commands to both - see
#1102.
Test Plan:
- TextUpdateTest fails without native changes, now passes with them.
- ExpandingText example no longer crashes.
- See More in Groups app no longer crashes.
Summary:
@nicklockwood - Could I get a review of this?
Just took `RCTTextField` and ported it from `UITextField` to `UITextView` as you mentioned in another discussion, and removed any `UITextField` specific attributes.
- How do you think this should behave when there are subviews?
- Do you know how we can respond to the `UIControlEventEditingDidEndOnExit` event to respond to submit? Because `UITextView` isn't a `UIControl` we can't just use `addTarget` with `UIControlEventEditingDidEndOnExit`.
- Any other feedback?
Still going to look over the `UITextView` docs in more detail and make sure we expose all important options, and add it to the UIExplorer example, just putting this out here for feedback.

Test Plan: Imported from GitHub, without a `Test Plan:` line.
Summary:
Fixes#979.
Previously, a Text whose width is determined automatically (as opposed to set by a container) would position the text incorrectly after an update to the text *if* the text's width did not change (i.e., when changing only digits in a font with tabular numbers).
Every time RCTShadowText's RCTMeasure runs, it sets the text container's size to be the maximum allowed size for the text. When RCTText's drawRect is called later, it relied on layoutSubviews having been called to set the text container's size back to the proper width. But if RCTMeasure returned the same dimensions as last time, then RCTText's frame wasn't reset and so layoutSubviews was never re-called. With this change, we set the textContainer's size each time we draw the text.
We could also fix this by using a different NSTextContainer instance in RCTMeasure. Not sure what the pros and cons of that are.

Summary:
For a very simple view I was observing that the text background was black and had to manually be set to transparent. This ensures that text nodes have a transparent background by default.
Closes https://github.com/facebook/react-native/pull/256
Github Author: James Ide <ide@jameside.com>
Test Plan:
This example component no longer renders what looks like a black block, and instead displays legible text.
var Example = React.createClass({
render: function() {
return (
<View style={styles.container}>
<Text>hello</Text>
</View>
);
},
});
var styles = StyleSheet.create({
container: {
flex: 1,
},
};
