无法将UIBezierPath放到MKMapView上

Question

我有一个MKMap，除此之外，我有一个小传说。标签＆amp;图例内的图像成功显示在地图上方，但矩形/贝塞尔曲线本身不显示。 我已经尝试将其添加为子视图，但失败了。有办法解决这个问题吗？

我需要触摸仍然启用地图。

感谢。

    //NZPost label
    LegendLabel *postLabel = [[LegendLabel alloc] initWithFrame:CGRectMake(conX + 50, 78, conY, 15) ];
    postLabel.text = @"NZ post";
    [self addSubview: postLabel];

    [self addSubview:inChargeImageView];

    //Incharge label
    LegendLabel *inChargeLabel = [[LegendLabel alloc] initWithFrame:CGRectMake(conX + 150, conY+18, 60, 15) ];
    inChargeLabel.text = @"In charge";
    [self addSubview: inChargeLabel];
