If you have access to the WWDC site:
https://developer.apple.com/wwdc/mac/library/samplecode/CustomMenus/Introduction/Intro.html
If not, then the short answer is that you need to send the action method
yourself and then close the menu. Personally, I prefer to wire up the action on
the menu item in IB and have my custom view use those.
- (void)sendAction {
NSMenuItem *actualMenuItem = [self enclosingMenuItem];
// Send the action set on the actualMenuItem to the target set on the
actualMenuItem, and make come from the actualMenuItem.
[NSApp sendAction:[actualMenuItem action] to:[actualMenuItem target]
from:actualMenuItem];
// dismiss the menu being tracked
NSMenu *menu = [actualMenuItem menu];
[menu cancelTracking];
[self setNeedsDisplay:YES];
}
