问题描述
我想自定义我在OS X上绘制窗口标题栏的方式。具体来说，我想做一些类似于Twitterrific应用程序，其中有一个自定义关闭按钮，没有最小/最大化按钮，窗口标题文本是右对齐的。不像Twitterrific，我不想定制绘制整个窗口（虽然我也不完全反对）。
I'd like to customize the way I draw the window title bar on OS X. Specifically, I'd like to do something like the Twitterrific app where there is a custom close button, no min/max buttons, and the window title text is right-justified. Unlike Twitterrific, I'm not looking to custom draw the entire window (though I'm not completely opposed to that either).
我已经看到了RoundWindow示例在可爱与爱以及Apple提供的RoundTransparentWindow示例，但似乎都不合适。
I've already seen the RoundWindow sample on Cocoa With Love as well as the RoundTransparentWindow example Apple provides, but neither seems appropriate.
推荐答案
如果你不想使用无边框窗口类，那么你可以做几件事。
If you don't want to use a borderless window class then you can do a couple of things.
首先，你可以使用自定义close / min / [NSWindow standardWindowButton：] 。一旦你得到的按钮，你可以定位/删除它/ etc ...
First, you can customize the close/min/max buttons buy using -[NSWindow standardWindowButton:]. Once you get the button you can position it/remove it/etc...
你可以通过设置标题为 @自定义标题， 。然后你可以添加一个 NSTextField 来绘制你自己的标题通过执行以下 [[[NSWindow contentView] superview] addSubview：textField] 。
You can customize the title by setting the title to @"". Then you can add a NSTextField to draw your own title by doing the following [[[NSWindow contentView] superview] addSubview:textField].
这可能是最简单的方法。
This is probably the easiest way to do things.
另一种方法是自定义绘制所有窗口标题栏的视图等。
Another way to do this is to customize the view that draws all the window title bar, etc...
NSWindow的内容视图位于主题视图中。你可以继承主题视图，并做你自己的图纸。唯一的问题是主题视图是一个私人类，所以你必须要小心。
NSWindow's content view's is inside a "theme view". You can subclass the theme view and do your own drawing. The only problem is that the theme view is a private class so you'll have to be careful.
