what should problem?

this example link..

your url not correct, should use @"http://www.maps.google.com/maps?saddr=%@&daddr=%@" if try launch google maps iphone's web browser. sample url: http://www.maps.google.com/maps?saddr=22.990236,72.603676&daddr=23.023537,72.529091

for more details google maps url scheme, can visit this documentation.

if want launch native ios google maps iphone, can following:

- (void)test {      nsurl *appurl = [[nsurl alloc] initwithstring:[nsstring stringwithformat:@"comgooglemaps://?saddr=%@&daddr=%@", @"22.990236,72.603676", @"23.023537,72.529091"]];      nsurl *weburl = [[nsurl alloc] initwithstring:[nsstring stringwithformat:@"http://www.maps.google.com/maps?saddr=%@&daddr=%@", @"22.990236,72.603676", @"23.023537,72.529091"]];      // if can launch native ios google maps app     if ([[uiapplication sharedapplication] canopenurl:appurl]) {         [[uiapplication sharedapplication] openurl:appurl];     }     // launch web browser, if no native ios google maps app installed     else {         [[uiapplication sharedapplication] openurl:weburl];     }  } 

if want draw routes in mapview, can use google maps directions service, can visit this documentation details using directions request url.
