It can be done like this:

-(IBAction)showButtonAction:(id)sender {
    [[NSApplication sharedApplication] beginSheet:panelOutlet
                                   modalForWindow:self.window
                                    modalDelegate:self
                                   didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:)
                                      contextInfo:nil];
}

Attention:

Don't forget to uncheck NSPanel's Visible At Launch checkbox in Attributes Inspector and Release When Closed if you will use this panel not once.

Result:

Isn't this `NSSheet` instead of `NSPanel`? – Joe Huang Feb 18 '17 at 13:16
