iOS MapBox RMShape [英] iOS MapBox RMShape

问题描述

我是刚开始使用RMPolylines和RMShapes的人，我认为我可以正确执行此代码，但是地图上没有显示任何内容:

I am new to using RMPolylines and RMShapes and i think i am executing this code correctly but nothing is showing up on the map:

RMMapBoxSource *tilesource = [[RMMapBoxSource alloc] initWithMapID:kMapID];

[mapView setTileSource:tilesource];

 NSArray *locations = [NSArray arrayWithObjects:[[CLLocation alloc] initWithLatitude:-33.981595 longitude:151.072900],[[CLLocation alloc] initWithLatitude:-33.981560 longitude:151.073544],[[CLLocation alloc] initWithLatitude:-33.981560 longitude:151.073845],[[CLLocation alloc] initWithLatitude:-33.981666 longitude:151.074016], nil];

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

annoation43.userInfo = locations;
[annoation43 setBoundingBoxFromLocations:locations];
[mapView addAnnotation:annoation43];

-(RMMapLayer *)mapView:(RMMapView *)mapViewer layerForAnnotation:(RMAnnotation *)annotation 
{
    if (annotation.isUserLocationAnnotation)
        return nil;

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

    shape.lineColor = [UIColor orangeColor];
    shape.lineWidth = 5.0;

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

    return shape;
    NSLog(@"It is working Dora!");
}

所以我认为我在这里做错了什么，但我无法选择它-如果需要更多代码或信息，请告诉我.

So i think i have done something wrong here but i cannot pick it - if any more code or information is needed just let me know.

推荐答案

好的，现在已经解决了，这似乎是一个简单的问题，但是如果您知道详细的原因，那么我很乐意听到！

Okay it is fixed now and seems to be a simple issue but if you know a detailed WHY this happened I would love to hear it!

添加了以下内容:

mapView.delegate = self;

我以为我已经设置了代表，但显然没有！

I thought i had already set the delegate but evidently not!
