Plotting Route with Multiple Points in iOS

Question

I am trying to display a route with multiple points in the provided Maps application.

I have figured out how to display a route between two points following this post. I am building a list of multiple points following these directions.

From what I understand, opening a maps.google.com (in iOS) will open the maps application (or Safari if Maps is not available).

The result is the Maps application is still only showing a route between the start and destination. The points added with mrad parameters are not being displayed.

Is it possible to display a route with multiple destinations in iOS at all (without building my own mapping system)?

To your question, the answer is YES.

But I'll stop trying to look intelligent right there. You're looking at the wrong SO question and answer. What you are looking for is a two step process:

use the GMaps Directions API to get a list of waypoints etc
draw a line using those points.

Luckily, there's apparently a Github project that does what you need. I didn't use it, so I don't know it's quality, but it's certainly much better than me explaining here how to do it.

https://github.com/kishikawakatsumi/MapKit-Route-Directions

I advise you to look at it.

I'm pretty sure it's against the terms of services to use google directions API on an Apple map. :( – deepwinter Apr 17 '14 at 23:36
That's an old question, and today on iOS7 you have MKDirections. – Cyril Godefroy May 06 '14 at 14:16

Just wrote a small sample using Google maps api V3 to show directions on iOS 6+ https://github.com/manishnath/iOSPlotRoutesOnMap

Here is the simple And easy code to get Connected route via Multiple location. to get complete project just go on-https://github.com/vikaskumar113/RouteWithMultipleLocation

   NSArray *dictionary = @[
                              @{
                                @"Source_lat": @"28.6287",
                                @"Source_lon": @"77.3208",
                                @"Dest_lat": @"28.628454",
                                @"Dest_lon": @"77.376945",
                                @"S_address": @"Vaishali,Delhi",
