- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {

    self.txtfield.text = [arrNum objectAtIndex:row];
    self.numPicker.hidden = TRUE;
}

Answer 1

Put the date picker inside a view with a 'Done' button and present that view modally. Set the value of text filed in the action for the Done button instead of didSelectRow delegate method. Then dismiss the modal view.

In addition you can add a cancel button to the view to directly dismiss it.
