Swift 3 macOS,设置默认按钮样式

Swift 3 macOS, set default button style

创建新 NSButton 时,如何将其样式设置为默认样式?

let (nomplusbut) = NSButton(frame: CGRect(x: 200, y: iy, width: 300, height: 40))
(nomplusbut).title = "Pfad öffnen..."
(nomplusbut).target = (self, action: #selector(buttonAction)) as AnyObject?
(nomplusbut).isBordered = true
(nomplusbut).setButtonType(NSMomentaryPushInButton)

arraybut.append(nomplusbut)

print(array[array.count - 1].stringValue)
self.view.addSubview(arraybut[arraybut.count - 1])

我想要的风格:

当前样式:

您应该将按钮的 bezelStyle 更改为 rounded,例如:

nomplusbut.bezelStyle = .rounded
