如何使用NSTitlebarAccessoryViewController？ [英] How to use NSTitlebarAccessoryViewController?

问题描述

有人可以告诉我如何使用NSTitlebarAccessoryViewController来为示例添加子视图吗？由于我是Mac编程的新手，您可能必须从基础进行解释。

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.

推荐答案

NSTitlebarAccessoryViewController 用于将子视图添加到Windows标题栏中。

NSTitlebarAccessoryViewController is for adding subviews to the windows title bar.

这里是一个示例：
在界面生成器中设置视图。转到ʻapplicationDidFinishLaunching：方法，将视图添加到标题栏。

Here is a example: Set up a view in interface builder. Go to the `applicationDidFinishLaunching: method to add the view to the title bar.

代码如下：

NSTitlebarAccessoryViewController* vc = [[NSTitlebarAccessoryViewController alloc] init];

vc.view = self.view;
vc.layoutAttribute = NSLayoutAttributeRight;

[self.window addTitlebarAccessoryViewController:vc];

您可以使用视图的大小来使其适合标题栏。

You can play with the size of the view to make it fit into the title bar.

更新

OS X 10.11引入了新的 layoutAttribute 左。
现在总共有三个 layoutAttribute 。 底部在titleBar（如tabBar）下方添加一个条，并在左 / 右将子视图放在titleBar内。

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.
