ios - 更改 View + 以编程方式将变量发送到 View

Question

我有一个函数可以正确更改 View ，但它不会将变量传递到下一个 View 。我真的不是 Swift 专家，我不知道我的代码错误在哪里:

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "PaymentVC") as! PaymentViewController
self.present(newViewController, animated: true, completion: nil)
    newViewController.num_pal = num_words
    newViewController.l_origen = l_source
    newViewController.l_destino = l_target
    newViewController.espec = espec
    newViewController.user = user
    newViewController.pass = pass
    newViewController.texto = texto
    newViewController.modificado = modificado
    newViewController.texto_ant = texto_ant

非常感谢您的帮助。

Answer 1

self.present(newViewController, animated: true, completion: nil)应该是传数据之后，放在newViewController.texto_ant = texto_ant之后就可以了p>
