add customView to NSStatusItem

问题

I would like to create a status bar application which has non-menu style. same as FaceTab for facebook (I mean only interface, not functional)... this is my codes:

-(void)awakeFromNib{
    statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:NSVariableStatusItemLength] retain];
    [statusItem setView:customView];
    //[statusItem setMenu:menu];
    [statusItem setTitle:@"Status"];
    [statusItem setHighlightMode:YES];
}

..... so once I Use NSMenu everything works fine but when I use NSView and CustomView outlet nothing appear on menu bar. Help plz!

There are several moving parts involved, so the best advice I can give is to check out this excellent example project from Vadim Shpakovski.

At the end of your awakeFromNib method, you may need to call retain on the statusItem so that it doesn't go out of scope. I was struggling with this same problem, and adding [statusItem retain]; fixed it so that I now see my Status menu in the Mac OS status bar.

-(void)awakeFromNib{
    statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:NSVariableStatusItemLength] retain];
    [statusItem setView:customView];

    // in my code, this is uncommented, and menu is an instance variable.
    //[statusItem setMenu:menu];

    [statusItem setTitle:@"Status"];
    [statusItem setHighlightMode:YES];

    // this was needed to get the icon to display in the status bar.
    [statusItem retain];
}
