WatchKit App as Controller for iOS Device

Is it possible to have a WatchKit app be a controller for it's parent iOS app?

I want to have buttons on the WatchKit app that cause an action on the iPhone app, but I can't find a way to get that going. Tried sending a notification - no joy.

Tried using WKInterfaceController.openParentApplication but that doesn't work either.

Can someone point me in the right direction?

Thanks.

Here is what my handleWatchKitExtensionRequest looks like. Check the spelling of this method in your code. You didn't spell it right in the comment and that would cause a unrecognized selector crash.

-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
    NSString* command = [userInfo objectForKey:@"command"];
    NSString* uuid = [userInfo objectForKey:@"uuid"];

    if (command == nil)
    {
        reply(nil);
    }
    else
    {
        if ([command isEqualToString:@"startTrip"])
        {
            ...
            //The uuid of the trip is returned to the watch app
            reply(@{@"uuid": uuid});
        }
        else if ([command isEqualToString:@"stopTrip"])
        {
            ...                
            reply(nil);
        }
        else if ([command isEqualToString:@"pauseTrip"])
        {
            ...
            reply(nil);
        }
        else if ([command isEqualToString:@"resumeTrip"])
        {
            ...                
            reply(nil);
        }
    }
}
