It is hard to customize a UIPickerView.
很难自定义 UIPickerView。
You might opt to use it in its default appearance or trying to simulate a UIPickerView using another UIKit component such as UITableView. There are some libs that are using UITableView to simulate a more flexible UIPickerView.
你可以选择使用它的默认外观，或者尝试使用另一个 UIKit 组件（例如 UITableView）来模拟 UIPickerView。有一些库使用 UITableView 来模拟更灵活的 UIPickerView。

You can change selected color by putting tableview cell in it.
您可以通过将 tableview 单元格放入其中来更改所选颜色。
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {
UITableViewCell *cell = (UITableViewCell *)view;
if( cell == nil ) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];
[cell setBackgroundColor:[UIColor redColor]];
[cell setBounds: CGRectMake(0, 0, cell.frame.size.width -20 , 44)];
cell.textLabel.text = [self.userNameArray objectAtIndex:row];
cell.userInteractionEnabled = NO;
}
return cell;
}

UIPickerViewhas subviews. Assigning an image to a view and adding it to the subview at index 2, would change the background of pickerview.
UIPickerView有子视图。将图像分配给视图并将其添加到索引 2 处的子视图，将更改 pickerview 的背景。
I had had a same kinda problem :-) See my question here!! Customize UIPickerView's Skin with images

The API does not provide a way to change the style and color of selection dialer. You can change only inner view of the picker how u want to design. As the UIPickerView don't have the UI_APPEARANCE_SELECTOR.
API 不提供更改选择拨号器的样式和颜色的方法。您只能更改选择器的内部视图如何设计。由于 UIPickerView 没有 UI_APPEARANCE_SELECTOR。
