Wheel Picker Dialog - StansAssets/com.stansassets.ultimate-mobile GitHub Wiki

The UM_WheelPickerDialog is a simple dialog containing native NumberPicker for Android and UIPickerView for iOS. This component allows your app user to pick any data from wheel picker that you want.

using SA.CrossPlatform.UI;

First al all you need to set data for our picker and then create a new instance of it:

var values = new List{"Test 1", "Test 2", "Test 3"};
var picker = new UM_WheelPickerDialog(values);

You can also define the default value if you need it. For example, if you want "Test 3" preselected as the default value:

var picker = new UM_WheelPickerDialog(values, 2);

Then just call Show() to show your picker:

picker.Show(result =>
{
    if (result.HasError)
    {
        UM_DialogsUtility.DisplayResultMessage(result);
    }
    else
    {
        switch (result.State)
        {
            case UM_WheelPickerState.InProgress:
                Debug.Log($"User in progress, current picked value: {result.Value}");
                break;
            case UM_WheelPickerState.Done:
                UM_DialogsUtility.ShowNotification($"User picked item: {result.Value}");
                break;
            case UM_WheelPickerState.Canceled:
                UM_DialogsUtility.ShowNotification($"User canceled picker dialog.");
                break;
            default:
                throw new ArgumentOutOfRangeException();
        }
    }
});

Also, you can look on native wheel pickers here for iOS and for Android.
