How to programmatically close/minimize my app

Removed for clarity.

Actually I wanted to hide the app when close button is closed such that it shall be active still. Which I was doing. I was basically facing the problem with Minimize the app. I don't know why the [NSApp miniaturizeAll:self]; is not functioning as expected.

Hi,
Thank you very much for your response. But unfortunately that also didn't work. I don't know how can I achieve this.

Hi,

I have fixed my problem of miniaturizing the window. It was quite cool.
{
NSApplication *application = [NSApplication sharedApplication];
NSWindow *keyWindow = [application keyWindow];
[keyWindow miniaturize:keyWindow];
}

My app has KeyWindow but not MainWindow, because my app's window is NSBorderlessWindowMask.

Thanks alot for all of your effort.
