Mapbox-ios如何删除MGLFeature

我通过visibleFeaturesInRect得到了一个有作用域的MGLFeature对象，因为这些对象可能是MGLPolygonFeature，MGLPolylineFeature等。我不知道它是什么，所以我想直接删除它通过removeLayer。

通过：

if (features.count > 0) {
        for (id<MGLFeature> feature in features) {
            MGLStyleLayer * layer = feature;
            [self.mapView.style removeLayer:layer];
        }
    }

我们找到的数据：

<MGLPolygonFeature: 0x600000f20310; identifier = "china.18", count = 113, bounds = { sw = {26.9, 78.4}, ne = {36.5, 99.1}}, attributes = {
    ADCODE93 = 540000;
    ADCODE99 = 540000;
    AREA = "114.331";
    "BOU2_4M_" = 179;
    "BOU2_4M_ID" = 54;
    NAME = "\U897f\U85cf\U81ea\U6cbb\U533a";
    PERIMETER = "76.629";
}>,
<MGLPolygonFeature: 0x600000f20150; identifier = "china.18", count = 113, bounds = { sw = {26.9, 78.4}, ne = {36.5, 99.1}}, attributes = {
    ADCODE93 = 540000;
    ADCODE99 = 540000;
    AREA = "114.331";
    "BOU2_4M_" = 179;
    "BOU2_4M_ID" = 54;
    NAME = "\U897f\U85cf\U81ea\U6cbb\U533a";
    PERIMETER = "76.629";
}>
