NSTitlebarAccessoryViewController
is for adding subviews to the windows title bar.
Here is a example:
Set up a view
in interface builder. Go to the `applicationDidFinishLaunching: method to add the view to the title bar.
The code would be the following:
NSTitlebarAccessoryViewController* vc = [[NSTitlebarAccessoryViewController alloc] init];
vc.view = self.view;
vc.layoutAttribute = NSLayoutAttributeRight;
[self.window addTitlebarAccessoryViewController:vc];
You can play with the size of the view to make it fit into the title bar.
Update
OS X 10.11 introduced the new layoutAttribute
left
.
There are now three layoutAttribute
s in total. bottom
adds a bar beneath the titleBar (like the tabBar) and left
/right
places your subview within the titleBar.
