在「界面」構建器中，如何將自定義按鈕添加到窗口標題欄？

Question

在我的OS X應用程序，使用Interface Builder，我有一個看起來像這樣的窗口：

我想一個按鈕添加到右側，來實現這一目標：

如果這是可能的，我該怎麼做？

Answer 1

這是不可能的界面生成器做的，但是你可以把它與編碼的點點做：

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. 

Answer 2

雨燕2.2和自動佈局，創建一個「OK」按鈕向右標題欄：

let myButton = NSButton() 
myButton.title = "OK" 
myButton.bezelStyle = .RoundedBezelStyle 

let titleBarView = window!.standardWindowButton(.CloseButton)!.superview! 
titleBarView.addSubview(myButton) 
myButton.translatesAutoresizingMaskIntoConstraints = false 
titleBarView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:[myButton]-2-|", options: [], metrics: nil, views: ["myButton": myButton])) 
titleBarView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-1-[myButton]-3-|", options: [], metrics: nil, views: ["myButton": myButton])) 

具有自動佈局，你不需要硬編碼按鈕的框架。即使您調整窗口大小，它總是在標題欄的右側。
