MapBox缩放级别不被接受 [英] MapBox zoom level not honored

问题描述

我已经使用RMMapView构建了一个控件. 我还从MapBox下载了一个地图以供离线使用，并相应地设置了最小和最大缩放级别，如下所示:

I've built a control using the RMMapView. I've also downloaded a map from MapBox to be offline available, and set the minimum and maximum zoom levels accordingly, like this:

RMMapboxSource * tileSource = [[RMMapboxSource alloc] initWithMapID:DEBUG_MAP_ID];
RMMapView *mapView = [[RMMapView alloc] initWithFrame:self.view.bounds andTilesource:tileSource];
mapView.minZoom = [[[tileSource infoDictionary]objectForKey:@"minzoom"] intValue];
mapView.maxZoom = [[[tileSource infoDictionary]objectForKey:@"maxzoom"] intValue];
[mapView setZoom:mapView.minZoom animated:YES];
mapView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
mapView.adjustTilesForRetinaDisplay = YES;
[mapView setHideAttribution:YES];
[self.view addSubview:mapView];

一切都很好，但是一旦我开始缩小，无论我设置的是什么，似乎都没有遵循最小缩放级别，并且地图也消失了，因为它没有该级别的图块.

All good, but once I start zooming out, it seems like the min-zoom level is not honoured, no matter what I set it to, and the map disappears because it doesn't have tiles for that level.

这里有什么我想念的吗?词典中的值很好，缩放级别已正确设置.最小和最大缩放都适用，这两个似乎都不起作用.

Is there anything I'm missing here? The values in the dictionary are good, the zoom levels are set correctly. This applies to both the min-and max zoom, neither of them seem to have effect.

(在一个简短的旁注中，我找不到MapBox的开发人员论坛.他们确实有一个支持页面，但是可以归结为FAQ，请给我们发电子邮件或付费获得支持.这是最好的选择，放置这些问题的StackOverflow吗?)

(On a quick side-note, I could not find a developer forum for MapBox. They do have a support-page, but it comes down to FAQ, e-mail us or pay for support. Is the best go-to place for these issues StackOverflow?)

推荐答案

我在支持电子邮件中回答了您，但是尝试将mapView属性添加到之后，将其添加到视图层次结构中.

I answered you on support email, but try changing the mapView properties after you've added it to the view hierarchy.
