UIPickerView selection indicator not visible in iOS10

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?

This is a custom view which contains a UIPickerView

-(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(@"App_Generic_Button_Text_Done", @"")];    }    -(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;    NSDictionary *dict = [dataArray objectAtIndex:row];    label.text = @"Test";    return label;}
