推荐答案

您可以获得Windows内容视图的superview并添加自定义视图那。只要确保你的视图正确的位置。下面是一些示例代码：

You can get the superview of the windows content view and add a custom view to that. Just make sure you position your view correctly. Here is some sample code:

NSView *frameView = [[window contentView] superview];
NSRect frame = [frameView frame];

NSRect otherFrame = [otherView frame];
otherFrame.origin.x = NSMaxX( frame ) - NSWidth( otherFrame );
otherFrame.origin.y = NSMaxY( frame ) - NSHeight( otherFrame );
[otherView setFrame: otherFrame];

[frameView addSubview: otherView];

这里 otherView 放在您的标题栏。这个代码不会工作，虽然如果有一个工具栏按钮 - 他们会重叠。幸运的是有一个API来获取工具栏按钮，以便您可以计算位置：

Here otherView is the view you want to put in your title bar. This code won’t work though if there is a toolbar button - they would overlap. Luckily there is an API to get the toolbar button so you can calculate the position:

NSButton *toolbarButton = [window standardWindowButton: NSWindowToolbarButton];
otherFrame.origin.x = NSMinX( [toolbarButton frame] ) - NSWidth( otherFrame );

您还必须确保视图的自动调整大小的掩码设置为窗口的右上角：

You also have to make sure that the autosizing masks for your view are set up so that it stays in the upper right corner of the window:

[otherView setAutoresizingMask:NSViewMinXMargin | NSViewMinYMargin];
