Answer 1

它不可能与Interface Builder一起使用,但是您可以通过一点点编码来完成它:

NSButton *closeButton = [window standardWindowButton:NSWindowCloseButton]; // Get the existing close button of the window. Check documentation for the other window buttons.
NSView *titleBarView = closeButton.superview; // Get the view that encloses that standard window buttons.
NSButton *myButton = …; // Create custom button to be added to the title bar.
myButton.frame = …; // Set the appropriate frame for your button. Use titleBarView.bounds to determine the bounding rect of the view that encloses the standard window buttons.
[titleBarView addSubview:myButton]; // Add the custom button to the title bar.
