OS X URL handler, but when launching the application?

Question

I've set a URL handler "soon" when my app is launching: in -(void)applicationDidFinishLaunching:(NSNotification*) :

[[NSAppleEventManager sharedAppleEventManager] setEventHandler:self andSelector:@selector(getUrl:withReplyEvent:) forEventClass:kInternetEventClass andEventID:kAEGetURL];
LSSetDefaultHandlerForURLScheme((CFStringRef)@"myScheme", (__bridge CFStringRef)[[NSBundle mainBundle] bundleIdentifier]);

It works as expected, the getUrl:withReplyEvent: is called whenever an URL with myScheme:// scheme is opened!

But if my app is not running (quit), if in Safari I open an URL such as myScheme://some_valuable_info?action=doSomething, it launched my app... but how do i know I've been launched by a URL handler? How can I get the URL that trigger my application launch?

Responding to myself:

The eventHandler must be registered in the applicationWillFinishLaunching: , not in applicationDidFinishLaunching:

If the app is launched due to an URL handler, you'll still get the evenHandler callback, but only if you registered it very soon in the launching process.
