Answer 1

Add optgroup at last and it works... :)

<select>
  <option selected="" disabled="">Select a value</option>
  <option>Grumpy wizards make toxic brew for the evil Queen and Jack</option>
  <option>Quirky spud boys can jam after zapping five worthy Polysixes</option>
  <option>The wizard quickly jinxed the gnomes before they vaporized</option>
  <option>All questions asked by five watched experts amaze the judge</option>
  <optgroup label=""></optgroup>
</select>

Check this :- UIKitUICatalog/UIPickerView

You cannot customize the appearance of picker views.

But you can go for an alternative. You can return a custom UILabel in this delegate method:-

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
UILabel *label = [[UILabel alloc] init];
// Set frame, font color, font size, text, etc properties here.
return label;

}
