We had the problem on iOS WebViews that local cookies (stored in local HTTPCookieStorage, set with [react-native-cookie](https://github.com/shimohq/react-native-cookie) ) were not added in loadRequests. On Android the local stored cookies were sent like expected.
This kinda "hacky" solution is the only way we found, that works for us.
The stack overview link is in the code below.
If someone finds a better solution we would very much like to accept that.
This PR fixes two crashes when enableWebKit is true (which was the default) on iOS 9.x. The first one when the WebView component was mounted (fixes issue #150) and the second one, when the component was unmounted (fixes issue #213).
The first problem happen when the RNCWKWebView.m was loaded:
The programming guide for WebKit (version 2006) ([pdf](http://mirror.informatimago.com/next/developer.apple.com/documentation/Cocoa/Conceptual/DisplayWebContent/WebKit_DisplayWebContent.pdf)) from Apple said, that it is (was) required to check if the 'new' WebKit Framework was available. This was required when the WebKit framework was only available on Mac OS X (10.2) when the Safari was installed. 😆
Because WebKit is (currently..) a fix part of iOS we didn't need this check this anymore to determinate if WebKit is available. I also see no other reference that this is required in iOS so I just remove this code. Without this code the WebView works also on iOS 9.x.
The second issue happen when the WKWebView was removed from the native view hierarchy. Its required (only on iOS 9) to remove the UIScrollView delegate before cleaning up the webview.
Its possible to try this PR with:
```
npm install --save "react-native-webview@jerolimov/react-native-webview#fix-ios9-crash"
# or
yarn add "react-native-webview@jerolimov/react-native-webview#fix-ios9-crash"
```
If you use CocoaPods, you should also update your Pods with
```
cd ios && pod update && cd ..
```

BREAKING CHANGE: Communication from webview to react-native has been completely rewritten. React-native-webview will not use or override window.postMessage anymore. Reasons behind these changes can be found throughout so many issues that it made sense to go that way.
Instead of using window.postMessage(data, *), please now use window.ReactNativeWebView.postMessage(data).
Side note: if you wish to keep compatibility with the old version when you upgrade, you can use the injectedJavascript prop to do that:
const injectedJavascript = `(function() {
window.postMessage = function(data) {
window.ReactNativeWebView.postMessage(data);
};
})()`;
Huge thanks to @jordansexton and @KoenLav!
Added a new cacheEnabled prop to toggle Android & iOS webview caching behavior.
BREAKING CHANGE: This change makes caching enabled by default when previously there was no caching behavior which may cause unexpected behaviour changes in your existing implementations.
* fix(WKWebview): [iOS] Add shared process pool so cookies and localStorage are shared across webviews (#68)
* Add optional shared process pool
BREAKING CHANGE: useSharedProcessPool prop is set to true by default. If you want the old behavior, please use useSharedProcessPool={false}
In the current code using `startInLoadingState` and `injectedJavaScript` will result in an infinite loading state if `injectedJavaScript` fails to evaluate for some reason. This adds a red box error explaining there was a failure to evaluate javascript. In my case this was do to the JS string not returning a valid type so I've added a that as a potential solution in the error message and added some documentation to the API Reference with some additional warnings.
To reproduce the existing behavior setup a webview with `startInLoadingState` and `injectedJavaScript` that returns an invalid type (in my case it returned a function). You should see an infinite loading state as `onLoadEnd` is never called.
Try the same with this branch and you'll get a nice red box error suggesting one potential solution to the problem.
