jsContext snippet

let script: JSValue = jsContext.objectForKeyedSubscript("getImageURL")
[jsContext callWithArguments:@["FirstParam",^(NSString* callbackValue) {
  NSLog(@"Got a value: %@",callbackValue)
}]

basically I have a javascript function that looks like this:

	function getImageURL(object, callback) {
	object.executeActionById("takeScreenshot");
        object.onScreenshotReady(function(imageName) {
            alert(imageName);
            callback(imageName);
        });
      };
            
And all I really want is imageName on the iOS side. So I'm trying to call the callback part of it on iOS and get imageName.
onScreenshotReady is async so I need to wait for it to finish before I get my imageName. So I created a callback within it

Hi @acegreen,
In addition to my first question, how can I create a method that will not generate an image on tradingview, but generating a base64 image and saving it to my local directory.

Thanks in advance..=
