您可以实现委托的pickerView:viewForRow:forComponent:reusingView:方法并从中返回UILabel实例:

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
    UILabel* label = (UILabel*)view;
    if (view == nil){
       label= [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 190, 44)];

       label.textAlignment = UITextAlignmentRight;
       //Set other properties if you need like font, text color etc
       ...
    }
    label.text = [self textForRow:row forComponent:component];
    return label;
}
