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..=
