James Andersen updated CB-10269:
--------------------------------
Attachment: ios-wkwebview-exec.js
I've had some success working around this issue by adding this [modified
ios-wkwebview-exec.js|^ios-wkwebview-exec.js] to
{{merges/ios/plugins/cordova-plugin-wkwebview-engine/src/www/ios}} so that it
replaces the one that currently ships with the plugin. The only modification
I've made is to check for the WKWebView before replacing the "cordova/exec"
module:
{code}
// Temporary work around for https://issues.apache.org/jira/browse/CB-10269
until it is fixed
if (window.webkit && window.webkit.messageHandlers &&
window.webkit.messageHandlers.cordova &&
window.webkit.messageHandlers.cordova.postMessage) {
// unregister the old bridge
cordova.define.remove('cordova/exec');
// redefine bridge to our new bridge
cordova.define("cordova/exec", function (require, exports, module) {
module.exports = execProxy;
});
}
{code}
> [iOS 8] cordova-plugin-wkwebview-engine breaks Cordova iOS 4.0.0 under iOS 8

> Key: CB-10269
> URL: https://issues.apache.org/jira/browse/CB-10269
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin WKWebViewEngine
> Affects Versions: 4.0.0
> Environment: Cordova tools 5.4.1
> Cordova iOS platform 4.0.1
> iOS Simulator 8.4
> cordova-plugin-wkwebview-engine plugin
> Reporter: Ivan Karpan
> Priority: Critical
> Labels: cordova-ios-4.1.0
> Attachments: ios-wkwebview-exec.js
>
>
> When launching on iOS 8.4 simulator the following error breaks JS execution
> early on:
> ios-wkwebview-exec.js:127 TypeError: undefined is not an object (evaluating
> 'window.webkit.messageHandlers')
> So inclusion of 'cordova-plugin-wkwebview-engine' plugin breaks support of
> iOS versions previous to 9.0. I assume ios-wkwebview-exec.js should have
> environment checks before using WKWebView bridge...
> Exclusion of the same plugin breaks the project at all. Are there any
> fallback mechanics in place?
