Ios RMPolylineAnnotation未出现在地图上（mapbox）

我试图将RMPolylineAnnotation添加到我的mapbox地图中，但由于某些原因，它没有出现。我不确定是否丢失了绘图过程中使用的调用或函数。我用来添加它的代码如下：

for (id key in dFeatures)
        {
            RMPolylineAnnotation *polylineAnnotation = [[RMPolylineAnnotation alloc] initWithMapView:self.rmMapView points:[dFeatures objectForKey:key]];
            [polylineAnnotation setLineWidth:10.0f];
            [polylineAnnotation setLineColor:[UIColor orangeColor]];

            [self.rmMapView addAnnotation:polylineAnnotation];
        }

dFeatures只是一个字典，它包含许多用于初始化RMPolylineAnnotations的点数组，请参见以下内容：

(lldb) po dFeatures

如果RMPolylineAnnotation不算作实际注释（即，它是否应该调用此方法？），for循环肯定会将其添加到RMMapView中的“\u visibleAnnotations”数组中

在我看来，您是在为集合中的每个点添加一条多段线的实例，而不是一条包含所有这些点的多段线

我有完全相同的错误，这是由于我的代码返回了一条长度为零的线（RMShape*）（即P1和P2是同一点）。这似乎在层渲染代码中导致了一些被零除的问题。我的代码大致如下，通过添加if（）部分，不再出现错误：-）

不抱歉，我应该更清楚一点，字典可以包含多个数组。我使用键名来标识不同的数组，因此您可以看到，此字典包含一个名为“Blacka_trail_a”的键条目，[dFeatures objectForKey:key]访问使用此键名存储的数组。这就是为什么我对正在发生的事情感到如此困惑，因为我觉得剩下的代码应该是正确的？嗨，我更新了我的原始帖子，在缩放时显示了一个错误，你知道为什么我现在会出现这个错误吗？谢谢。我想我可能在错误的地方调用了它，我目前在viewDidLoad中运行了这段代码，我猜它需要在比这晚很多的时候调用。关于代码应该放在哪里有什么建议吗？你能解决你的问题吗？你能解决这个问题吗？
