我正在MacOS上的Swift 4中使用NSAlert将登录对话框放在一起。这是我到目前为止的代码:
func dialogOKCancel(question: String, text: String) -> (String, String) {
let alert = NSAlert()
alert.messageText = question
alert.informativeText = text
alert.alertStyle = .warning
alert.addButton(withTitle: "Login")
alert.addButton(withTitle: "Cancel")
let unameField = NSTextField(frame: NSRect(x: 0, y: 0, width: 200, height: 24))
let passField = NSSecureTextField(frame: NSRect(x: 0, y: 0, width: 200, height: 24))
let stackViewer = NSStackView()
stackViewer.addSubview(unameField)
alert.accessoryView = stackViewer
let response: NSApplication.ModalResponse = alert.runModal()
if (response == NSApplication.ModalResponse.alertFirstButtonReturn) {
return (unameField.stringValue, passField.stringValue)
} else {
return ("", "")
}
}
当我执行
unameField
时,这可以很好地显示passField
或alert.accessoryView = passField
。但是我想在同一个对话框中显示两个字段。如您所见,我已经尝试了NSStackView(和其他),但是我还没有找到同时显示这两个元素的解决方案。 最佳答案
希望能帮到您...
您可以使用NSStackView和addSubview 2项目:unameField和passField。
但是您必须为NSStackView设置框架,并在NSStackView上设置2个项目。
这是我的代码,您可以引用:
let unameField = NSTextField(frame: NSRect(x: 0, y: 2, width: 200, height: 24))
let passField = NSSecureTextField(frame: NSRect(x: 0, y: 28, width: 200, height: 24))
let stackViewer = NSStackView(frame: NSRect(x: 0, y: 0, width: 200, height: 58))
stackViewer.addSubview(unameField)
stackViewer.addSubview(passField)
alert.accessoryView = stackViewer
这是我的结果:
