iOS Parse Geopoints & Mapbox формы

Question

Поэтому мне интересно, как пойти, чтобы пойти вокруг координат разбора и рисунок формы с помощью MapBox.

Я могу извлечь координаты и построить их индивидуально (с использованием parse )Карта штрафа:

PFQuery *locationQuery = [PFQuery queryWithClassName:@"Location"];
[locationQuery whereKeyExists:@"location"];
locationQuery.cachePolicy = kPFCachePolicyNetworkElseCache;
[locationQuery findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (!error) {
        // The find succeeded.
        NSLog(@"Successfully retrieved %lu scores.", (unsigned long)objects.count);
        NSLog(@"Object is %@ and %@", [objects objectAtIndex:0],[objects objectAtIndex:1]);

        for (PFObject *gp in objects) {

            //How to get PFGeoPoint and then a location out of an object
            PFGeoPoint *location = [gp objectForKey:@"location"];

            NSLog(@"Hi there my name is: %f", location.latitude);

            CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(location.latitude, location.longitude);

            //This is how to populate the data with a title
            NSString *title = [NSString stringWithFormat:@"%@", gp.createdAt];

            RMPointAnnotation *annotation3 = [[RMPointAnnotation alloc] initWithMapView:mapView coordinate:coordinate andTitle:title];
            [mapView addAnnotation:annotation3];

        }

    } else {
        // Log details of the failure
        NSLog(@"Error: %@ %@", error, [error userInfo]);
    }
}];

.

Добавление формы на карту (используя mapbox ) также выполняется:

//Line for streets location arrays, etc MapBox
    NSArray *locations = [NSArray arrayWithObjects:[[CLLocation alloc] initWithLatitude:-33.980852 longitude:151.072498],
                          [[CLLocation alloc] initWithLatitude:-33.981769 longitude:151.072300],
                          [[CLLocation alloc] initWithLatitude:-33.982018 longitude:151.072257],
                          [[CLLocation alloc] initWithLatitude:-33.982187 longitude:151.072225], nil, nil];

    RMAnnotation *annoation43 = [[RMAnnotation alloc] initWithMapView:mapView coordinate:((CLLocation *)[locations

.

ObjectAtIndex: 0]). Координата andtitle: @ "Hola Biatches!"];

    annoation43.userInfo = locations;
    [annoation43 setBoundingBoxFromLocations:locations];
    [mapView addAnnotation:annoation43];
    NSLog(@"It is working Dora!");

-(RMMapLayer *)mapView:(RMMapView *)mapViewer layerForAnnotation:(RMAnnotation *)annotation {

    if (annotation.isUserLocationAnnotation)
        return nil;

    RMShape *shape = [[RMShape alloc] initWithView:mapView];

    //Line dashes and colours and widths, etc
    shape.lineColor = [UIColor orangeColor];
    shape.lineWidth = 4.0;
    shape.scaleLineWidth = YES;
    shape.scaleLineDash = YES;
    shape.lineDashLengths = [NSArray arrayWithObjects:[NSNumber numberWithInt:4], [NSNumber numberWithInt:6], nil];
    shape.lineDashPhase = 3.0f;



    for (CLLocation *location in (NSArray *)annotation.userInfo)
        [shape addLineToCoordinate:location.coordinate];

    return shape;


}

Мне интересно, как я получал Mapbox, чтобы нарисовать форму из этих координат?У меня было несколько попыток, и я никудаюсь, чтобы кто-то с лучшим умом, чем я бы очень оценил.Если вам нужна дополнительная информация, дайте мне знать.

Answer 1

Я понял это - мое решение, которое я пытался, был в порядке - я инициализировал массив в цикле и поэтому он был воссоздан на массиве каждый раз, и поэтому перезаписал каждую новую координату и пытаясь нарисовать форму, используя только одну координатуОтказ

PFQuery *locationQuery2 = [PFQuery queryWithClassName:@"Location"];
    [locationQuery2 whereKeyExists:@"location"];
    locationQuery2.limit = 4;
    locationQuery2.cachePolicy = kPFCachePolicyNetworkElseCache;
    [locationQuery2 findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {
            // The find succeeded.
            NSLog(@"Successfully retrieved %lu scores.", (unsigned long)objects.count);
            NSLog(@"Object is %@ and %@", [objects objectAtIndex:0],[objects objectAtIndex:1]);
            NSMutableArray *locations = [[[NSMutableArray alloc] init] mutableCopy];

            for (PFObject *gp in objects) {

                //How to get PFGeoPoint and then a location out of an object
                PFGeoPoint *location = [gp objectForKey:@"location"];

                NSLog(@"Hi there my name is not: %f", location.latitude);

                CLLocation *coordinate = [[CLLocation alloc] initWithLatitude:location.latitude longitude:location.longitude];

                //Line for streets location arrays, etc MapBox
                [locations addObject:coordinate];

                RMAnnotation *annoation43 = [[RMAnnotation alloc] initWithMapView:mapView coordinate:((CLLocation *)[locations objectAtIndex:0]).coordinate andTitle:@"Hola biatches!"];

                annoation43.userInfo = locations;
                [annoation43 setBoundingBoxFromLocations:locations];
                [mapView addAnnotation:annoation43];
                NSLog(@"It is working Dora!");


                NSLog(@"Yeah its is: %@", locations);
            }

        } else {
            // Log details of the failure
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
    }];
