Ios 第一次轻触UITextField时显示键盘。inputView=UIPickerView

在这件事上，我对斯威夫特毫无敬意

我正在将

UIPickerView

配置为

UITextField

的

inputView

一切正常，但当我第一次点击这个特定的

UITextField

时，显示的是键盘，而不是

UIPickerView

，如果我再次点击它，就会显示

UIPickerView

有人知道我做错了什么吗

请参阅我的代码的某些部分

@IBAction func textFieldEditingMot(sender: UITextField) {

    let motivoPicker: UIPickerView = UIPickerView()

    motivos = ["Pedido de demissão","Dispensa sem justa causa","Dispensa com justa causa", "Término do contrato de experiência"]

    motivoPicker.delegate = self
    motivoPicker.dataSource = self
    motivoTextField.inputView = motivoPicker

}

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int
{
    return 1
}

func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int
{
    return motivos.count
}

func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int)
{
    motivoTextField.text = motivos[row]
}

func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String?
{
    return motivos[row]
}

确保您正在设置UITextFieldDelegate，然后我还会移动所有这些：

let motivoPicker: UIPickerView = UIPickerView()

motivos = ["Pedido de demissão","Dispensa sem justa causa","Dispensa com justa causa", "Término do contrato de experiência"]

motivoPicker.delegate = self
motivoPicker.dataSource = self
motivoTextField.inputView = motivoPicker

要查看DIDLOAD

您是否设置了UITextFieldDelegate？我是这方面的新手，您能解释一下我是如何做到这一点的吗？仅此而已！我把这个放在

iAction

中，非常感谢你的帮助，它工作得非常好。太棒了！很高兴我能帮上忙！：）
