TextInput Field with Pickerview instead of keyboard

Question

I want to add a pickerview instead of a keyboard for a specific textfield and fill the picker view with content directly in the .m file

What is the easiest way to accomplish that?

Can I do this directly in the interface builder or do i have to add much code on my own?

For any Xamarin.iOS developers, here's how to do it in C#

public partial class MyViewController : UIViewController
{
    public override void ViewDidLoad()
    {
        base.ViewDidLoad();

        ConfigurePicker();
    }

    void ConfigurePicker()
    {
        var pickerTextField = new UITextField();

        var picker = new UIPickerView
        {
            Model = new PickerViewModel(),
            ShowSelectionIndicator = true
        };

        var screenWidth = UIScreen.MainScreen.Bounds.Width;
        var pickerToolBar = new UIToolbar(new RectangleF(0, 0, (float)screenWidth, 44)) { BarStyle = UIBarStyle.Default, Translucent = true };
        var flexibleSpaceButton = new UIBarButtonItem(UIBarButtonSystemItem.FlexibleSpace);
        var doneButton = new UIBarButtonItem(UIBarButtonSystemItem.Done, (sender, e) => pickerTextField.ResignFirstResponder());
        pickerToolBar.SetItems(new[] { flexibleSpaceButton, doneButton }, false);

        pickerTextField.InputView = picker;
        pickerTextField.InputAccessoryView = pickerToolBar;
    }

    class PickerViewModel : UIPickerViewModel
    {
        int[] _pickerSource = new []{ 1, 2, 3, 4, 5 };

        public override nint GetRowsInComponent(UIPickerView pickerView, nint component) => _pickerSource.Count;

        public override string GetTitle(UIPickerView pickerView, nint row, nint component) => _pickerSource[(int)row];

        public override nint GetComponentCount(UIPickerView pickerView) => 1;
    }
}

You can use custom button on uitextfield. and can fire action for that button is pressed. when pickerview dismiss then just add the selected text in textbox.

Answer 3

Set tag to that textField and check condition in textFieldDidBeginEditing method write picker code.

Answer 4

UIPickerView *picker = [[UIPickerView alloc] init];
picker.delegate = self;
picker.dataSource = self;
textField.inputView = picker;

Answer 5

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    [self createPickerView]; 
}

-(void)createPickerView
{
    //create Picker Here
}

or Put Button over in place textfeild give inaction according to it.
