ios - 以编程方式切换UIAlert Controller

我正在快速创建一个包含3个文本字段和一个Switch的注册对话框，并成功添加了三个文本字段两个Alert。以下代码显示了相同的内容。

 let alertController = UIAlertController(title: "Register", message: "", preferredStyle: .Alert)
    let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { (action) in
        // ...

        exit(0)
    }
    alertController.addAction(cancelAction)

    let OKAction = UIAlertAction(title: "Sign UP", style: .Default) { (action) in
        // ...
        let name0 = alertController.textFields![0] as UITextField
        print("Text field: \(name0.text)")

        let email1 = alertController.textFields![1] as UITextField
        print("Text field: \(email1.text)")

        let company2 = alertController.textFields![2] as UITextField
        print("Text field: \(company2.text)")


    }

    alertController.addAction(OKAction)

    alertController.addTextFieldWithConfigurationHandler { (textField) in
        textField.placeholder = "Name"
        textField.keyboardType = .EmailAddress
    }

    alertController.addTextFieldWithConfigurationHandler { (textField) in
        textField.placeholder = "Email"
        textField.secureTextEntry = false
    }

    alertController.addTextFieldWithConfigurationHandler { (textField) in
        textField.placeholder = "Company"
        textField.secureTextEntry = false
    }


            self.presentViewController(alertController, animated: true) {
                // ...
            }

现在我需要以编程方式向``警报 View ''添加一个开关。我们正在Swift2中进行此操作。有可能吗？，我是Swift的新手。

最佳答案

这可能对您有帮助。

在alertController.view.addSubview(createSwitch())之后的上面的代码中添加此方法调用alertController.addAction(OKAction)。

func createSwitch () -> UISwitch{


    let switchControl = UISwitch(frame:CGRectMake(10, 20, 0, 0));
    switchControl.on = true
    switchControl.setOn(true, animated: false);
    switchControl.addTarget(self, action: "switchValueDidChange:", forControlEvents: .ValueChanged);
    return switchControl
}

func switchValueDidChange(sender:UISwitch!){

    print("Switch Value : \(sender.on))")
}
