Question

I am using a WebView in my application and it the page I am loading has some existing javascript function calls that were used in a windows environment and should now be used in a mac application. My issue is that the current javascript (ported from a windows app where the following works) function calls objective C like this:

function callObjectiveC
{
   window.external.MY_ObjectiveCFunction();
}

I have been trying to use:

+ (NSString *)webScriptNameForSelector:(SEL)sel
{
    if (sel == @selector(MyObjectiveCFunction)) 
    {
    return @"My_ObjectiveCFunction";
    }   
}

based on: https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/WebKit/Protocols/WebScripting_Protocol/Reference/Reference.html but to no avail. Is there a way to do this? I can call the objective C method whatever I want I just need to be able to map that to what is in the existing javascript.

Thanks,
c.

Figured out a solution:

- (id)invokeUndefinedMethodFromWebScript:(NSString *)name withArguments:(NSArray *)args
{
NSLog(@"invoke undefined method: %@", name);
if([name isEqualToString:@"My_ObjectiveCFunction"])
{
    return NSSelectorFromString(@"My_ObjectiveCFuntion");   
}
return nil;
}
