UIAlertView／UIActionSheet

UIAlertView

         //设置提醒视图样式
         oneButtonAlert.alertViewStyle = UIAlertViewStyle.LoginAndPasswordInput

         //来获取提醒视图上的文本框
         var textField : UITextField? = oneButtonAlert.textFieldAtIndex()

         //设置文本框占位符
         textField?.placeholder = "请输入账号"

     }
