iOS share extension in chrome - google-chrome

Question

Just added share extension to my app.
It's working fine in safari.
When launching it from Chrome the "ExtensionPreprocessingJS.js" isn't called.
as a result the following code is not invoked:
MyExtensionJavaScriptClass.prototype = {
run: function(arguments) {
// Pass the baseURI of the webpage to the extension.
arguments.completionFunction({"baseURI": document.baseURI});
},
Please advise.

Answer 1

That behavior is documented as being a Safari option, not something that applies to every web browser.
In Share extensions (on both platforms) and Action extensions (iOS only), you can give users access to web content by asking Safari to run a JavaScript file and return the results to the extension.
[Emphasis mine]

Answer 2

Try to put/replace/add this to your info.plist of extension
<dict>
<key>NSExtensionAttributes</key>
<dict>
<key>NSExtensionActivationRule</key>
<dict>
<key>NSExtensionActivationSupportsText</key>
<true/>
<key>NSExtensionActivationSupportsWebPageWithMaxCount</key>
<integer>1</integer>
<key>NSExtensionActivationSupportsWebURLWithMaxCount</key>
<integer>1</integer>
</dict>
<key>NSExtensionJavaScriptPreprocessingFile</key>
<string>DemoPreprocessor</string>
</dict>
<key>NSExtensionMainStoryboard</key>
<string>MainInterface</string>
<key>NSExtensionPointIdentifier</key>
<string>com.apple.share-services</string>
</dict>

No need for that complicated stuff. This works both in Google Chrome and Safari:
override func viewDidLoad() {
super.viewDidLoad()
for item in extensionContext!.inputItems {
if let attachments = item.attachments {
for itemProvider in attachments! {
itemProvider.loadItemForTypeIdentifier("public.url", options: nil, completionHandler: { (object, error) -> Void in
if object != nil {
println(object) //This is your URL
}
})
}
}
}
}
