Question

我的应用程序中有一个“与我们联系”页面，其中包含4个不同的区域。在每个区域下，我都有一个下拉菜单，其中将每个联系人的姓名填充到UIPickerview中。所有4个下拉列表均填充JSON数据中的所有名称。我要对每个区域进行检查，以检查其ID是否等于该区域的人的ID，然后仅显示这些名称。目前，这是我正在使用的代码。如何检查特定ID？

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

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {


  if pickerView == thePicker {
        return contactUsInfo.count
  }
  else if pickerView == thePicker2 {
        return contactUsInfo.count
  }
  else if pickerView == thePicker3 {
        return contactUsInfo.count
  }
  else if pickerView == thePicker4 {
        return contactUsInfo.count
  }
    return 1
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

    if pickerView == thePicker {
        return contactUsInfo[row].fullName
    }
    else if pickerView == thePicker2 {
        return contactUsInfo[row].fullName
    }
    else if pickerView == thePicker3 {
        return contactUsInfo[row].fullName
    }
    else if pickerView == thePicker4 {
        return contactUsInfo[row].fullName
    }

    return ""
}

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

    if (pickerView == thePicker)  {
        self.DropdownField.text = self.contactUsInfo[row].fullName

    }
    else if (pickerView == thePicker2)  {
        self.DropdownField2.text = self.contactUsInfo[row].fullName

    } else if (pickerView == thePicker3)  {
        self.DropdownField3.text = self.contactUsInfo[row].fullName

    } else if (pickerView == thePicker4)  {
        self.DropdownField4.text = self.contactUsInfo[row].fullName

    }
}

我对此的想法是

var id = contactUsInfo.id

if contactUsInfo.id == (id: 1, id: 2, id: 3, etc) {
pickerview == thePicker {
return contacUsInfo[row].fullName
}
} else if if contactUsInfo.id == (id: 4, id: 5, id: 6, etc) {
pickerview == thePicker2 {
return contacUsInfo[row].fullName
}
}

我知道此代码不正确，这就是我正在寻找的答案。

将JSON数据传递到单独的UIPickerviews中
