OpenStreetMap/iOS：标记和路线不能一起工作
我是 OpenStreetMap 的新手，但有相当多的 iOS 开发经验。我正在开发一个应用程序，该应用程序上有一个 OpenStreetMap 地图，带有响应触摸的标记，以及从一系列位置以编程方式生成的路线。我可以让所有的部分都工作起来，但是放在一起：不太好。
在下面的示例中，我将标记放在地图上，并将 mapView 挂接到委托，这样我就可以响应标记上的触摸。然后，再次按照示例，我创建一个 CMRoute 并将其添加为子图层 ([mapView.contents.overlay addSublayer:walkRoute.path];)。这样做本质上是将标记隐藏在路线子层下；他们不再对触摸做出反应。
谁能给我指出一个方向，让我能够拥有地图视图和路线子图层，并且仍然能够检测标记触摸？我不要求提供代码（尽管那会很好），但要考虑如何实现这一点。
谢谢
I am a newbie to OpenStreetMap, but have a fair amount of iOS development experience. I'm working on an app that will have an OpenStreetMap map on it, with markers that respond to a touch, and a route generated programmatically from an array of locations. I can make all the pieces work, but together: not so good.
Following examples, I put the markers on the map, and hook the mapView to a delegate, so I can respond to touches on the markers. Then, again following examples, I create a CMRoute and add it as a sublayer ([mapView.contents.overlay addSublayer:walkRoute.path];). Doing that essentially hides the markers under the route sublayer; they no longer respond to a touch.
Can anyone point me in a direction that will give me the means to have a mapView and a route sublayer and still be able to detect marker touches? I don't ask for code (though that would be nice) but thoughts on how this could be accomplished.
Thanks
