Can I call javascript function from iphone native function?

Question

I am developing an iPhone/iPad App using phonegap/cordova.

Now as i have to integrate some devices which are having SDK for xcode supportable.The issue i am facing is that i wanted to call javascript function from my native functions. I know how to call native funciton from javascript but looking for vice-versa.

I have searched alot over internet but they all are describing how to do it by using webview. I don't want to use webview as i am not familier with objective-c coding and also for that i have to change my HTMl Code into webview as my code is fully developed in HTML5 and javascript by using cordova plugin.

Please suggest me if any other way is also available.

If you want to call JavaScript from native code, you will have to write native code. — user529758

You can call a javascript function from native code like this:

    [self.webview stringByEvaluatingJavaScriptFromString:@"myfunc();"];

Old question but my first hit on Google. So I give it a try. You have to call self.commandDelegate evalJS. Other methods like writeJavascript are deprecated.

Inside your plugin-code call

[self.commandDelegate evalJs:@"console.log('Greetings from Native');"];
