Google Map Direction API Return Zero Results Swift

问题

My App using Google Maps Direction API to draw route between any two positions (origin - direction positions)user pin it.

I used the API like this way:

https://maps.googleapis.com/maps/api/directions/json?origin=(fromLat),(fromLng)&destination=(toLat),(toLng)&mode=(travelMode)&departure_time=now&alternatives=true&language=(lang)

The problem is sometimes the response return Zero Results, like this :

{
  "geocoded_waypoints": [
    {},
    {}
  ],

  "routes": [],

  "status": "ZERO_RESULTS"
}

I searched a lot but no useful results.

Anyone faced this problem?

Could this problem be because I used the free API?

I will be thankful for any help.

Thanks.

回答1:

If there will be no path then it returns the same.

See this link : Path Information

Hope this helps!

UPDATE:

Try to covert latitude-longitude into address and pass it over the URL and it will solve the issue. CLGeocoder might help you to do the same.

回答2:

It's because of wrong lat-long for the destination. Also path is not available for the requested Travel mode.

回答3:

Try with this google API:

https://maps.google.com/maps?saddr=%@,%@&daddr=%@,%@

Pass latitude, longitudes to above API. You will get the result.
