macOS How to hide my app with Obj-C code

[Oats]

I've got a utility app I'm developing for OS X (hopefully targeting 10.5 and up). My window floats above other windows, and occasionally I want to hide the my app/window and let users continue running whatever program was behind it. Similar to if the user pressed "cmd-H" to hide my app.

The problem is, I don't know how to do this programmatically with cocoa. I can hide my window, but my app's menubar is still frontmost. Things I have tried that did not work:

[NSApp hide:self];
[NSApp deactivate];

Please help, thanks!

In formulating the question for this post, I finally was able to choose the right google keywords to lead me to a solution. This seems to work:

	ProcessSerialNumber psn;
	GetFrontProcess (&psn);
	ShowHideProcess (&psn,false);

I find it hard to believe [NSApp hide:nil] didn't work.
