Lukas Wöhrl 992e37c8bc Fix sizing of non strech items
Summary:
Fixes the sizing of items so that under most scenarios it calcultes its height by it's content for non exact measurings. This introduces a new useLegacyStretchBehaviour flag on the config to opt out of this change as it is breaking.

Valentin Shergin 64c327ae68 Fixed issue where setting `zero scale` transfrom matrix to UIView brokes `hitTest` mechanism
Summary:
The Math Strikes Back

Several related things:
 * When we specify `scale: 0;` style for some view it ends up with calling `CATransform3DScale` with zero scale parameter.
 * In this case `CATransform3DScale` returns transform matrix full of zeros. It actually depends on representation and matrix-type (2d or 3d) but in UIView debugger it appears as [0, 0, 0, 0, ...]. And probably it is correct result.
 * By default, for hit-testing, UIKit uses specially optimized logic based on GPU/CALayer infrastructure under the hood. And the transform matrix full of zeros breaks this algorithm. I guess, it happens because zero-matrix doesn't quite make sense.

So, `scale: 0;` is a weird edge case, and in this diff, we are trying to illuminate it by replacing with epsilon value.

Valentin Shergin 264d60b979 Setting `availableSize` for `RCTRootShadowView` on earlier stage
Summary:
Moving setting `availableSize` for `RCTRootShadowView` on earlier stage allows to prevent situations where `availableSize` is not specified yet, but Yoga layout is already happening.
Because `availableSize` equals {infinity, infinity} by default (in this case), Yoga returns a lot of nodes with infinit metrics, which confises UIKit.

Adam Comella 6fbc2c9972 iOS: Remove leading space from accessibilityLabel
Summary:
In some cases, the accessibilityLabel contains a leading space. This is because `RCTRecursiveAccessibilityLabel` adds a space before every iteration of the loop including the first.

After this change, the contract is that:
  - `RCTRecursiveAccessibilityLabel` always returns a string with a leading space.
  - `accessibilityLabel` never returns a string with a leading space.

**Test plan**

I created a test app with the following code:

```
<View style={{height: 100, width: 100, backgroundColor: 'steelblue'}} accessible={true}>
  <View style={{height: 20, width: 20, backgroundColor: 'red'}} accessibilityLabel='One' />
  <View style={{height: 20, width: 20, backgroundColor: 'yellow'}} accessibilityLabel='Two' />
  <View style={{height: 20, width: 20, backgroundColor: 'green'}} accessibilityLabel='Three' />
</View>
```

Before this change, the accessibilityLabel of the outermost View was " One Two Three" (notice the leading space).

After this change, it is "One Two Three" as desired.

 * Introduces new property of `RCTRootShadowView` `availableSize` which represents exactly what we transmit to layout engine;
 * Illuminates conflict between logical `availableSize` and explicitly specified size of DOM node (current `size`);
 * Splits overcomplicated `setSize:forView:` method into two unrelated ones;
 * Changes actual values of `RCTRootViewSizeFlexibility` enum constants for simpler usage;
 * Completely removes `sizeFlexibility` concept from `RCTRootShadowView` (in favor of special values of `availableSize`);
 * Makes the code clearer finally.

This is beginning of big effort to improve `RCTRootView` and co.

Valentin Shergin f33f84e75f Deprecating/removing `setFrame`, `setLeftTop`, and co.
Summary:
Motivation:
 * `RCTShadowView`'s `frame` property actually represents computed layout of the view. We must not use it as a setter for yoga node styles;
 * Using `frame` and `setLeftTop` in existing way actually works only for view with absolute positioning, so it is super rare and special case;
 * Internally, setting `frame` only make sense to `RootView`, and in that case there we always must not change `origin` we are introducing `setSize` method.

Changes:
 * `[-RCTShadowView setFrame:]` was removed, `frame` property is readonly now;
 * `[-RCTShadowView setLeftTop:]` was removed; no replacement provided;
 * `[-RCTShadowView size]` read-write property was added;
 * `[-RCTUIManager setFrame:forView:]` was deprecated, use (just introduced) `setSize:forView:` instead;
 * `[-RCTUIManager setSize:forView:]` was added.

If you are still need some of removed methods, you are probably doing something wrong. Consider using `setIntrinsicContentSize`-family methods,
`setSize`-family methods, or (in the worst case) accessing `yogaNode` directly.

Martin Konicek 9dee696ed8 Add scrollToEnd to ScrollView and ListView
Summary:
**Motivation**

A basic task of making a React Native ScrollView or ListView scroll to the bottom is currently very hard to accomplish:
- https://github.com/facebook/react-native/issues/8003
- https://github.com/facebook/react-native/issues/913
- http://stackoverflow.com/questions/29829375/how-to-scroll-to-bottom-in-react-native-listview

**NOTE:** If you're building something like a chat app where you want a ListView to keep scrolling to the bottom at all times, it's easiest to use the [react-native-invertible-scrollview](https://github.com/exponent/react-native-invertible-scroll-view) component rather calling `scrollToEnd` manually when layout changes. The invertible-scrollview uses a clever trick to invert the direction of the ScrollView.

This pull request adds a `scrollToEnd` method which scrolls to the bottom if the ScrollView is vertical, to the right if the ScrollView is horizontal.

The implementation is based on this SO answer:

Summary:
Explain the **motivation** for making this change. What existing problem does the pull request solve?

This change is required when you try to set a focus on a view that doesn't exist and thus cannot be focused. In my specific use case, this occurred when trying to set a focus on a list item in a setInterval when the View (with the specific list item) had been popped. The while loop ran infinitely (eventually freezing the app) since the rootView doesn't exist. This adds that check and breaks out if so.

All obj-c tests ran successfully.

Luke Miles da9a712a9e Add a injectJavaScript method to the WebView component
Summary:
Currently, < WebView > allows you to pass JS to execute within the view. This works great, but there currently is not a way to execute JS after the page is loaded. We needed this for our app.

We noticed that the WebView had messaging support added (see #9762) . Initially, this seemed like more than enough functionality for our use case - just write a function that's injected on initial load that accepts a message with JS, and `eval()` it. However, this broke once we realized that Content Security Policy can block the use of eval on pages. The native methods iOS provide to inject JS allow you to inject JS without CSP interfering. So, we just wrapped the native methods on iOS (and later Android) and it worked for our use case. The method injectJavaScript was born.

Now, after I wrote this code, I realized that #8798 exists and hadn't been merged because of a lack of tests. I commend what was done in #8798 as it sorely solves a problem (injecting JS after the initial load) and has more features than what I'

Jake Dawkins 6234a5dfa2 Fix iOS Picker Item Colors
Summary:
I want to resolve #11170 by passing the `color` prop from `PickerIOS.Item` to its implementation.

In `RCTPicker.m`, the label.textColor was already being set and used, but there was nothing referencing the past prop. I passed the prop to the implementation, checked if it exists, and if not, set the default color, like before.

I visually tested the **Colorful Pickers** example in UIExplorer. Those picker `Item`s pass in a `color` prop.

Pieter De Baets e1577df1fd Move all header imports to "<React/..>"
Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.

Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Martin Kralik 26e373c903 fix view clipping to operate on ui hierachy
Summary:
There was a bug in the view clipping logic.
Clipping works on uiview hierarchy, but I've been using `reactSuperview` to get clipping rect for my parent.
This is incorrect in a case where these two hierarchies don't match and there are some views between a view and its `reactSuperview`.

So we should really use normal `superview`. A minor complication is that `superview` is `nil` if we are clipped.
We could remember what our last `superview` was, but that's extra data we have to manage. Instead I use one clever trick to avoid doing so.
(Let me know if it makes sense based on my inline documentation.)

Geordie a4bb4d25f5 Only retain the previousViews that need to be validated
Summary:
Fixes #4740, where views would unnecessarily be retained after performing `navigator.pop()` - this was particularly problematic for big lists and memory-intensive custom views.

This fix causes no functional change: `_previousViews` are only used in the loop starting at line 564 to ensure that the JavaScript and Native navigation stacks are equivalent at all times. As we do in this fix, that loop limits itself to only the views expected to be on the React navigation stack. So overall this change makes the code logically 'more correct'.

Tested by checking that `_previousViews.count` is always equivalent to `previousReactCount` in the loop (which means we could remove the complex `MIN(... MIN(previousReactCount, _previousViews.count)` in the loop too, but I wanted to keep the diff as small as possible for now).

Mehdi Mulani 97153d68cf Guard against bad values set in RCTCustomScrollView
Summary:
UIScrollView's internal logic with scroll indicator dies when bad values (e.g. NaN/Infinity) are set on the position/size.
We already guard UIManager with these checks but the RCTScrollView's underlying scrollview (RCTCustomScrollView) can get these set from other places, and we're seeing crashes in this area.

Jacob Parker abb8ea3aea Implement a postMessage function and an onMessage event for webviews …
Summary:
JS API very similar to web workers and node's child process.

Work has been done by somebody else for the Android implementation over at #7020, so we'd need to have these in sync before anything gets merged.

I've made a prop `messagingEnabled` to be more explicit about creating globals—it might be sufficient to just check for an onMessage handler though.

Antti Moilanen 72e203bf95 Fix ScrollView's snap index when scrolling forward and user taps the screen again while still scrolling
Summary:
Currently when snapping is used with ScrollView it calculates wrong snap index if user taps the screen second time while ScrollView is still scrolling. This happens because the code only adds 1 to the snap index when translationAlongAxis is smaller than zero. When user taps screen second time the translationAlongAxis is 0 and snap index ends up being one less than it should. This causes the ScrollView to scroll one step backwards.

Bug can be reproduced with the new examples I added to UIExplorer's ScrollView in [scrollview-snap-bug-example branch](https://github.com/anttimo/react-native/tree/scrollview-snap-bug-example).

Fix can be verified by running the same examples with the ScrollView fix in [scrollview-snap-bug-example-with-fix branch](https://github.com/anttimo/react-native/tree/scrollview-snap-bug-example-with-fix).
