Providing lists

In this recipe, we will learn how to use the UIPickerView class.

Getting ready

The UIPickerView class provides us with a control whose functionality is similar to a listbox, specifically designed for human fingers touching the screen. Its main difference to a common listbox is that each column can have its own number of rows. To get started, create a new iPhone project and name it PickerViewApp .

How to do it...

  1. Open the MainController.xib file in Interface Builder.

  2. Add a UILabel and a UIPickerView on the main View.

  3. Save the document.

  4. Back in MonoDevelop, create a nested class in the MainController class that inherits from UIPickerViewModel :

    private class PickerModelDelegate : UIPickerViewModel

  5. Add the following constructor and fields in the nested class:

    public PickerModelDelegate (MainController controller) {
  this.parentController = controller;
  this.transportList = new List<string>() { "On foot", "Bicycle", "Motorcycle", "Car", "Bus" };
  this.distanceList = new List...
