问题
How do I add the Share submenu in a Mac app? An example is Safari > File > Share. I poked at the Apple SharingServices sample code, but it does not include a working menu item.
Right now I have a button that displays a picker of available sharing services when tapped:
NSMutableArray *shareItems = [NSMutableArray arrayWithObject:[self.noteSynopsisView string]];
NSSharingServicePicker *sharingServicePicker = [[NSSharingServicePicker alloc] initWithItems:shareItems];
sharingServicePicker.delegate = self;
[sharingServicePicker showRelativeToRect:[self.shareButton bounds] ofView:self.shareButton preferredEdge:NSMaxYEdge];
I've also defined a Share submenu item under the File menu for my MainWindow.xib.
As I understand it, the NSSharingService list is being generated on the fly. So I can't really predefine the services to the menu item I have created in Interface Builder.
Thanks for your help.

Look at NSSharingService's +sharingServicesForItems:. In a -validateMenuItem: method you could create a submenu using the -title and -image of the NSSharingServices it returns. Associate each service with each menu item, and point the action of each menu item at this:
- (IBAction)shareFromService:(id)sender {
[[sender representedObject] performWithItems: arrayOfItemsToShare];
}
It's really quite simple. Apple did a good job on this one.

I find the gist can help you easily create a submenu of proper services. https://gist.github.com/eternalstorms/4132533
It's a NSSharingServicePicker category.
