Set Cocoa App Icon in Launchpad Programmatically

Question

I want to change Mac App icon in Launchpad programmatically, just like OS X Calendar app, which shows current date in Launchpad. But I can't find any document/resource online.

I tried changing Dock icon like this:

NSImage *image = [NSImage imageNamed:@"dockIcon2.png"];
[NSApp setApplicationIconImage:image];

But this only changes Dock icon, not Launchpad icon.

Is there a way to change (Mac) app icon in Launchpad programmatically?

Thanks!

Is your application signed? http://stackoverflow.com/questions/13324902/launchpad-icons-not-showing-nsdocktile-badge-anymore — , Feb 12 '16 at 05:36
@duskwuff Hi, I saw that post before. That topic is about showing a badge in Launchpad, not changing icon. But for your question, my app is signed, both for debug and release. — Zhigang An, Feb 12 '16 at 16:11

You cannot do this. App Icons have to be set when the app is compiled

So, it is like iOS calendar app, Apple has some private API, or root privilege to change icon, but other developers cannot? – Zhigang An Feb 12 '16 at 15:51
Correct. That is the case – Kyle Redfearn Feb 12 '16 at 19:02
