It's not safe... once the target is found (using
respondsToSelector:, you're right), the action is performed with:
[target performSelector:actionSelector withObject:sender];

crash.
The only safe thing you can image is to have an action selector with
no paramater at all.
I'm not actually performing the action, just getting the target, and
then calling the method myself, kinda like a delegate:
id target = [NSApp
targetForAction:@selector(notReallyAnAction:withArgument:)];
if (target != nil)
{
int returnValue = [target notReallyAnAction:foo withArgument:bar];
// Do something with returnValue
}
