body {
background: #ccc;
margin: 0;
padding: 0;
}
p {
margin: 0;
text-align: center;
position: relative;
top: 50%;
transform: translateY(-50%);
}
.wrap {
margin: 50px auto;
width: 500px;
}
.inner {
position: relative;
height: 100px;
width: 100%;
}
.left {
float: left;
background: #fff;
height: 100px;
position: relative;
width: 30%;
}
.right {
float: left;
background: #4c4c4c;
height: 100px;
padding: 0 40px;
width: 70%;
}
.border {
border: 1px solid yellow;
border-style: dashed;

width: 96%;
height: 80px;

border-top: 50px solid transparent;

}
<div class='wrap'>
<div class='inner'>
<div class='left'>
<p>Lorem Ipsum <br>Lorem ipsum dolor</p>
<div class='arrow-left'></div>
</div>
<div class='right'><p>Lorem Ipsum is placeholder text commonly used in the graphic, print, and publishing industries for previewing layouts and visual mockups.</p></div>

,而 //1. Create the alert controller.
let alert = UIAlertController(title: "Title", message: "Description", preferredStyle: .alert)
//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in

}
alert.addTextField { (textFieldPass) in
textFieldPass.placeholder = "Password"

alert.addAction(UIAlertAction(title: "Cancelar", style: .default, handler: { [weak alert] (_) in
print("cerrar")
}))
alert.addAction(UIAlertAction(title: "Aceptar", style: .default, handler: { [weak alert] (_) in
let textField = alert?.textFields![0]
let textFieldPass = alert?.textFields![1]
print("Text field: \(textField!.text)")
print("Text field: \(textFieldPass!.text)")
self.Autentificacion(usuario: textField!.text!, clave: textFieldPass!.text!)
