上次介紹到比較簡單的客製化alert，今天介紹稍微進階一點。
這樣的客製化好處是在於你不用每次都還要宣告alertViewController，然後addAction，最後present，蠻麻煩的。

帶一個textField的alert：

TAlertView.showAlertWith(title: "123", message: "123", setCancelTitle: "cancel", setConfirmTitle: "sdwe", delegate: self) { textField in
    textField.placeholder = "enter a number"
    textField.keyboardType = .numberPad
} completion: { textfield in
    GlobalAppSetting.shared.defaultADC = textfield.text!
    self.setPlanTableView.reloadData()
}

兩個的:

TAlertView.showAlertWith(title: "title", message: "message", setCancelTitle: "setCancelTitle", setConfirmTitle: "setConfirmTitle", delegate: self) { textField1 in
    textField1.placeholder = "placeholder1"
    textField1.keyboardType = .numberPad
} textFieldSet2: { textField2 in
    textField2.placeholder = "placeholder2"
    textField2.keyboardType = .numberPad
} completion: { textField1, textField2 in

    print("\(textField1.text!)")
    print("\(textField2.text!)")
}
