Answer 1

最后添加optgroup ，它可以工作... :)

<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>

Answer 2

检查一下： -UIKitUICatalog / UIPickerView

You cannot customize the appearance of picker views.

但是您可以选择其他方法。 您可以在此委托方法中返回自定义UILabel ：-

- (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;

}
