Possible issue with (de-)allocation of webview instances on iOS #11

Open ekirchdev opened 1 year ago

ekirchdev commented 1 year ago

Hello, I am using the webview to display content of a web page on a local web server. I manage with the iOS webview that the server is no longer accessible when I navigate to the webview and back again several times. Something seems to be wrong with the garbage collection there. The app is flooding a queue on the webserver, unfortunately I cannot debug the webserver further.

With Android, the problem does not happen. If I use the default NativeScript webview on iOS instead, it works without flooding the webserver's connection queue.

I have commented out various elements of the code, such as everything from initNativeView / disposeNativeView in index.ios.js, but that doesn't help and does not gain any further information...

I am sorry that I can't provide more details.

This javascript code is executed implicitly by the library, every time I create a webview instance by using executeJavaScript(scriptCode, stringifyResult).

As I don't really need it, I override the executeJavaScript function to block this logic. I don't really understand why, but my problem is solved!
