我目前正在尝试加载一些GPX路径，这些路径是作为数据图层添加到我的Mapbox项目中的。我似乎无法找到关于如何做到这一点的任何教程，并且文档非常少，但我认为我处于正确的路线。当设置我的RMMapBoxSource我使用：Mapbox在xcode中使用enableDataOnMapView时崩溃
normalTileSource = [[RMMapboxSource alloc] initWithMapID:[JSONDict objectForKey:@"normalJSON"] enablingDataOnMapView:rmMapView]
然而，这段代码似乎会导致我所内RMMapBoxSource缩小到这一功能的碰撞：
- (id)initWithTileJSON:(NSString *)tileJSON enablingDataOnMapView:(RMMapView *)mapView
崩溃，看来这行之后发生：
CLLocationCoordinate2D coordinate = {
.longitude = [[[[feature objectForKey:@"geometry"] objectForKey:@"coordinates"] objectAtIndex:0] floatValue],
.latitude = [[[[feature objectForKey:@"geometry"] objectForKey:@"coordinates"] objectAtIndex:1] floatValue]
};
这是因为.longitude参数期待一个浮点值是存在于每个字典/阵列条目，但是，由于这是行数据的geom etry实际上包含数组的数组（见下文）
(lldb) po feature
{
geometry = {
coordinates = (

谁能告诉我，我的意思是什么功能，可以用画我的GPX/RMPolylineAnnotation数据，我不能弄明白。
感谢
尝试：'.longitude = [[[[[功能objectForKey：@ “几何体”] objectForKey：@ “坐标”] objectAtIndex：我] objectAtIndex：0] floatValue]， .latitude = [[[[featureObjectForKey：@“geometry”] objectForKey：@“coordinates”] objectAtIndex：i] objectAtIndex：1] floatValue]'获取坐标的第i个“包”。 – Larme
因为它是一个Mapbox函数，我不确定是否允许改变它，所以我推测它们也会有一些函数来处理RMPolylineAnnotation。 –
