Question

In my app I want to show the Direction between two Place.

I get the Latitude & Longitude for Both two places.

and want add that lat,long in this URL,

   NSURL *strlist = [NSURL URLWithString:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f"]; 

But when i give lat,long Like this,

 NSURL *strlist = [NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%f,%f & daddr=%f,%f",c_lat,c_long,lat,lat]];

//c_lat – Current Latitude //in Double format
//c_long – Current Longitude //in Double format
//lat – Particular Place Latitude //in Double format
//lat – Particular Place Longitude //in Double format

In NSlog(“URL:%@”,strlist); I got NULL Value.

How to add that Lat & Long in NSURL ?

Answer 1

Remove the space between %f and &
Similarly remove the space between & and daddr

It should be like this

 NSURL *strlist = [NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f",c_lat,c_long,lat,lat]];
