如果附近有太多Map Pins，则MKMapView会聚类
[英]MKMapView clustering if too many Map Pins nearby
问题描述
I'm wondering if any of you knows a method (library, category, etc.) to cluster iOS MapAnnotations if there are many of them at the same location (eg 4 pieces in about 10m). 
我想知道是否有人知道一个方法（库，类别等）来集群iOS MapAnnotations，如果它们在同一位置有很多（例如，大约10米的4件）。
It doesn't matter to zoom in because they are still overlapping. 放大并不重要，因为它们仍然重叠。 I've already tried https://github.com/applidium/ADClusterMapView (and sombe other libs) but all of them are made for showing clusters in zoom-out-scenarios. 我已经尝试过https://github.com/applidium/ADClusterMapView （和sombe其他libs），但所有这些都是为了在缩小场景中显示集群而制作的。 None of them really respect the distance between annotations when zoomed in. 放大时，他们都没有真正尊重注释之间的距离。
I'm working on an app with an offline-db so a server-side solution is not an option. 我正在开发一个带有offline-db的应用程序，因此无法选择服务器端解决方案。
thank you for your help! 谢谢您的帮助！

You don't need 3rd party framework's anymore. 你不再需要第三方框架了。 iOS 11 has native clustering support. iOS 11具有本机群集支持。
You need to implement mapView:clusterAnnotationForMemberAnnotations: method. 您需要实现mapView:clusterAnnotationForMemberAnnotations:方法。

您应该查看CCHMapClusterController项目，看起来完全像您正在寻找的东西。

One alternative is the MapBox iOS SDK, which is an open source (BSD) library replicating MapKit behavior. 另一种选择是MapBox iOS SDK，它是一个复制MapKit行为的开源（BSD）库。 It does both annotation clustering and offline map layers. 它同时执行注释聚类和离线地图图层。
