I am using ReactNative in a hybrid App.

When I pop Native View Controller 2 off the Navigation stack, I get a seg fault on this line:

I believe what's happening:
Your code is listening to Nav Controller transitions, assuming that they are all from React Native Nav Controllers.
You are catching this one instead, which is actually a Native Nav Controller transition.
You start trying to access the pushed/popped view controllers as if they were react native view controllers.
In this case, the view controllers are not react native -> no navItem field -> seg fault.

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.

The fix for border smearing introduced a bug where borders + background would sometimes not be rendered if the view was created at a small size (e.g. zero) and then resized.
This diff fixes that by redrawing the border if the view size changes. There is some opportunity to optimize this in future by performing some logic up-front to detect if the redrawing is necessary, but I thought I'd keep it simple for this bug fix rather than risk introducing further bugs.

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.

Summary:
Both iOS and Android currently support some sort of native pull to refresh control but the API was very different. I tried implementing a component based on PullToRefreshViewAndroid but that works on both platforms.
I liked the idea of wrapping the ListView or ScrollView with the PullToRefreshView component and allow styling the refresh view with platform specific props if needed. I also like the fact that 'refreshing' is a controlled prop so there is no need to keep a ref to the component or to the stopRefreshing function.
It is a pretty rough start so I'm looking for feedback and ideas to improve on the API before cleaning up everything.
On iOS we could probably deprecate the onRefreshStart property of the ScrollView and implement the native stuff in a PullToRefreshViewManager. We could then add props to customize the look of the UIRefreshControl (tintColor). We could also deprecate the Android only component and remove it later.

I'm removing it, since the idea of creating a view based on set of initial properies is a bit flawed, since we cannot change it to another view later when props are changed.

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

Original github title: Exported a callback for native webview delegate method shouldStartLoadWithRequest
We have a requirement in our app, to open in mobile Safari, any http:// and https:// links displayed in a web view. Our web view is not full screen and is loaded with an HTML string from the backend. Displaying external content in that web view is outside of the scope of our app, so we open them in mobile Safari.
I've forked the WebView component and added a callback property, shouldStartLoadWithRequest, and modified the RCTWebView implementation of `webView:shouldStartLoadWithRequest:navigationType:`
to check if the shouldStartLoadWithRequest property is set.
If the property is set, `webView:shouldStartLoadWithRequest:navigationType:` passes the URL & navigationType to the callback. The callback is then able to ignore the request, redirect it, open a full screen web view to display the URL content, or even deep link to another app with LinkingIOS.openURL().
