问题是按钮let a = NSAlert() a.messageText = "Do you want go to A or B?" a.alertStyle = .informational a.addButton(withTitle: "Yes") a.addButton(withTitle: "No") a.beginSheetModal(for: self.view.window!, completionHandler: { (modalResponse) -> Void in if modalResponse == NSAlertFirstButtonReturn { // do stuff}在No之前显示，第二个按钮似乎是预选的。为什么会发生这种情况？

我需要按钮按照添加顺序显示，而不是预先选择按钮。

Answer 1

通过添加第一个“否”按钮修改订单，然后添加“是”

通过将keyEquivalent设置为“”

来禁用预选

let alert = NSAlert()
alert.messageText = "Do you want go to A or B?"
alert.alertStyle = .informational
alert.addButton(withTitle: "No")
alert.addButton(withTitle: "Yes")
alert.buttons[0].keyEquivalent = ""
...

NSAlert - 添加按钮没有出现在正确的顺序中
