Mapbox падает при использовании enableDataOnMapView в xcode
В настоящее время я пытаюсь загрузить некоторые трассы GPX, которые я добавил в качестве слоев данных в мои проекты Mapbox. Я не могу найти какие-либо учебные пособия о том, как это сделать, и документация весьма минимальна, но я думаю, что я на правильном пути. При настройке моего RMMapBoxSource я использую:
normalTileSource = [[RMMapboxSource alloc] initWithMapID:[JSONDict objectForKey:@"normalJSON"] enablingDataOnMapView:rmMapView]
Тем не менее, этот код, кажется, вызывает сбой, который я сузил до этой функции в RMMapBoxSource:
- (id)initWithTileJSON:(NSString *)tileJSON enablingDataOnMapView:(RMMapView *)mapView
Кажется, что сбой происходит после этой строки:
CLLocationCoordinate2D coordinate = {
.longitude = [[[[feature objectForKey:@"geometry"] objectForKey:@"coordinates"] objectAtIndex:0] floatValue],
.latitude = [[[[feature objectForKey:@"geometry"] objectForKey:@"coordinates"] objectAtIndex:1] floatValue]
};
Это происходит потому, что аргументы.longitude ожидают, что в каждой записи словаря / массива будет присутствовать одно значение с плавающей запятой, однако, поскольку это строковые данные, геометрия фактически содержит массив массивов (см. Ниже).

type = LineString;
};
properties = {
description = "";
id = "marker-hqqqqc9l0";
stroke = "#1087bf";
"stroke-opacity" = 1;
"stroke-width" = 4;
title = Route2;
};
type = Feature;
}
Может кто-нибудь сказать мне, какую функцию я должен использовать, чтобы нарисовать мои данные GPX / RMPolylineAnnotation, поскольку я не могу понять это.
Спасибо

-enablingDataOnMapView: Аргумент связан с серверными маркерами Mapbox, которые выбираются и автоматически добавляются на карту на основе изменений, которые вы сделали в онлайн-редакторе Mapbox. Это не полезно для ваших собственных пользовательских данных.
Так же mapID Аргументом является идентификатор карты Mapbox, а не JSON.
