ios - Swift - 由于 'textFields' 保护级别，无法访问 'fileprivate'

Question

我添加了一个对我的警报进行个性化设置的 Pod (PCLBlurEffectAlert) 编辑警报、警报操作和警报文本字段后，出现此错误，并且无法使用文本字段。我能做什么？

let alert1 = PCLBlurEffectAlertController(title: NSLocalizedString("AGGENTRATA", comment: ""),
                                   message: NSLocalizedString("insENTRATA", comment: ""),
                                   effect: UIBlurEffect(style: .dark),
                                   style: .alert)
    alert1.addTextField( with: { (textField: UITextField!) in
        textField.placeholder = NSLocalizedString("ENTRATA_LOCAL", comment: "") //impostiamo il segnaposto del field
        textField.isSecureTextEntry = false //se fosse un campo Password mettremmo true
        textField.keyboardType = UIKeyboardType.numberPad
    } )

    alert1.addAction(PCLBlurEffectAlertAction(title: NSLocalizedString("ANNULLA_LOCAL", comment: ""), style: .cancel,  handler: { (action) in
        UIView.animate(withDuration: 0.4, animations: {
            self.blurVisual.effect = nil
        })
    }))
    alert1.addAction(PCLBlurEffectAlertAction(title: NSLocalizedString("AGG", comment: ""), style: .default, handler: { (action) in
        UIView.animate(withDuration: 0.4, animations: {
            self.blurVisual.effect = nil
        })
        let textField = alert1.textFields![0] as UITextField

textfields 是 PCLBlurEffectAlertController 中的私有(private)变量。所以我们无法访问私有(private)变量。

fileprivate var textFields: [UITextField] = []

你可以这样使用:

var textfield1: UITextField?

let alert1 = PCLBlurEffectAlertController(title: NSLocalizedString("AGGENTRATA", comment: ""),
                                              message: NSLocalizedString("insENTRATA", comment: ""),
                                              effect: UIBlurEffect(style: .dark),
                                              style: .alert)
alert1.addTextField( with: { (textField: UITextField!) in
        textField.placeholder = NSLocalizedString("ENTRATA_LOCAL", comment: "") //impostiamo il segnaposto del field
        textField.isSecureTextEntry = false //se fosse un campo Password mettremmo true
        textField.keyboardType = UIKeyboardType.numberPad
        self.textfield1 = textField
} )

alert1.addAction(PCLBlurEffectAlertAction(title: NSLocalizedString("AGG", comment: ""), style: .default, handler: { (action) in
        let textField = (self.textfield1?.text as! NSString).floatValue
}))
