How to use NSTitlebarAccessoryViewController?

Question

Can anyone tell me how to use NSTitlebarAccessoryViewController, to add subview to a view with an example? As I am new to mac programming you may have to explain from basics. Please.

Answer 1

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 layoutAttributes in total. bottom adds a bar beneath the titleBar (like the tabBar) and left/right places your subview within the titleBar.
