如何将偏移量复选框列表添加到NSScrollView？

// 创建NSScrollView对象
let scrollView = NSScrollView(frame: NSRect(x: 0, y: 0, width: 200, height: 300))
scrollView.hasVerticalScroller = true
scrollView.autohidesScrollers = true

// 创建NSView对象
let contentView = NSView(frame: NSRect(x: 0, y: 0, width: 200, height: 300))

// 创建NSStackView对象
let stackView = NSStackView(frame: contentView.bounds)
stackView.orientation = .vertical
stackView.spacing = 10

// 创建偏移量复选框列表
let checkbox1 = NSButton(checkboxWithTitle: "选项1", target: nil, action: nil)
let checkbox2 = NSButton(checkboxWithTitle: "选项2", target: nil, action: nil)
let checkbox3 = NSButton(checkboxWithTitle: "选项3", target: nil, action: nil)

// 将复选框添加到NSStackView中
stackView.addArrangedSubview(checkbox1)
stackView.addArrangedSubview(checkbox2)
stackView.addArrangedSubview(checkbox3)

// 将NSStackView添加到NSView中
contentView.addSubview(stackView)

// 将NSView设置为NSScrollView的documentView
scrollView.documentView = contentView
