Cordova WKWebView Engine

This plugin makes Cordova use the WKWebView component instead of the default UIWebView component, and is installable only on a system with the iOS 9.0 SDK.

In iOS 9, Apple has fixed the issue present through iOS 8 where you cannot load locale files using file://, and must resort to using a local webserver. However, you are still not able to use XHR from the file:// protocol without CORS enabled on your server.

Installation

This plugin needs cordova-ios 4.0.0 - 5.x. This plugin is not supported on cordova-ios >6.0.0.

To install the current release:

cordova create wkwvtest my.project.id wkwvtest
cd wkwvtest
cordova platform add ios@4
cordova plugin add cordova-plugin-wkwebview-engine

To test the development version:

cordova create wkwvtest my.project.id wkwvtest
cd wkwvtest
cordova platform add https://github.com/apache/cordova-ios.git#master
cordova plugin add https://github.com/apache/cordova-plugin-wkwebview-engine.git#master

You also must have at least Xcode 7 (iOS 9 SDK) installed. Check your Xcode version by running:

xcode-select --print-path

Required Permissions

WKWebView may not fully launch (the deviceready event may not fire) unless if the following is included in config.xml. This should already be installed by Cordova in your platform config.xml when the plugin is installed.

config.xml

<feature name="CDVWKWebViewEngine">
  <param name="ios-package" value="CDVWKWebViewEngine" />
</feature>

<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

If using cordova-ios >= 5.1.0, it is recommended to include the following preference tag to only use the WKWebView which is a requirement for new App submissions to the AppStore:

<preference name="WKWebViewOnly" value="true" />

Notes

This plugin creates a shared WKProcessPool which ensures the cookie sharing happens correctly across WKWebView instances. CDVWKProcessPoolFactory class can be used to obtain the shared WKProcessPool instance if app creates WKWebView outside of this plugin.

On an iOS 8 system, Apache Cordova during runtime will switch to using the UIWebView engine instead of using this plugin. If you want to use WKWebView on both iOS 8 and iOS 9 platforms, you will have to resort to using a local webserver.

We have an experimental plugin that does this. You would use that plugin instead of this one.

Application Transport Security (ATS) in iOS 9

Starting with cordova-cli 5.4.0, it will support automatic conversion of the <access> tags in config.xml to Application Transport Security ATS directives.

Upgrade to at least version 5.4.0 of the cordova-cli to use this new functionality.

Enabling Navigation Gestures ("Swipe Navigation")

In order to allow swiping backwards and forwards in browser history like Safari does, you can set the following preference in your config.xml:

<preference name="AllowBackForwardNavigationGestures" value="true" />

You can also set this preference dynamically from JavaScript:

window.WkWebView.allowsBackForwardNavigationGestures(true)
window.WkWebView.allowsBackForwardNavigationGestures(false)

Disabling 3D Touch Link Previews

In order to disable preview popups when hard pressing links in iOS, you can set the following preference in your config.xml:

<preference name="Allow3DTouchLinkPreview" value="false" />

Limitations

If you are upgrading from UIWebView, please note the limitations of using WKWebView as outlined in our issue tracker.

Apple Issues

The AllowInlineMediaPlayback preference will not work because of this Apple bug. This bug has been fixed in iOS 10.
