title: UIPickerView selection indicator not visible in iOS10
body: <p>I build my project in Xcode 8. UIPickerView separator lines are not visible in iOS 10 simulator and the devices, but works fine on iOS 9.3 devices and simulator. I tried to adjust the UIPickerView back ground color, auto layouts and everything possible in the XIB, but nothing works. Anyone have an idea on this?</p>
  <p>This is a custom view which contains a UIPickerView</p>

  <pre><code>-(void)layoutSubviews{
      isShown = NO;
      [super layoutSubviews];
      
      //self.selectedDic = nil;
      
      self.doneBtn.tintColor = COLOR_DB3535;
      self.pickerView.backgroundColor = COLOR_DEDEDE;
      self.pickerView.showsSelectionIndicator = YES;
      
      [self.doneBtn setTitle:NSLocalizedString(@&quot;App_Generic_Button_Text_Done&quot;, @&quot;&quot;)];
      }
  
  
      -(UIView*)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
      UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
      label.tintColor = [UIColor clearColor];
      label.backgroundColor = [UIColor yellowColor];
      label.textColor = COLOR_666;
      label.font = [FontsManager getFONT_ROBOTO_LIGHT_16];
      label.textAlignment = NSTextAlignmentCenter;
