Hello Team, I am trying to display the line name corresponding to draw polyline in the apple map. when I used the draw function to draw the line name when polyline get render in the apple map. but these are too cluttered and it is not easy to readable. Please refer to the screenshot.I need a solution something like how apple shows the name for any road name, street name in the apple map.Please find the below Screenshots link :https://drive.google.com/open?id=1hCVGTvB7cytlcbHA2ZQ3gHd-ptkEK2ZLhttps://drive.google.com/open?id=1Ce8ebz8wSiJqGkV7THqcvNMehrMlYD1vCode which we are using to render the linename to map//// CustomOverlayPathRenderer.m// lineinspection//// Created by Rupendra Kumar on 13/02/17.// Copyright © 2017 Rupendra kumar.
