ios - How to get place name from lattitude and longitude? -


i getting latitude , longitude api, , need place name these cooridinates use block of code 

clgeocoder *ceo = [[clgeocoder alloc]init];  cllocation *locationatual=[[cllocation alloc] initwithlatitude:[[latlong objectforkey:@"latitude"] doublevalue]                                                       longitude:[[latlong objectforkey:@"longitude"] doublevalue]];  nslog(@"loc %@", locationatual);  [ceo reversegeocodelocation:locationatual  completionhandler:^(nsarray *placemarks, nserror *error) {   clplacemark *placemark = [placemarks objectatindex:0];   nslog(@"placemark %@",placemark);   //string hold address   nsstring *locatedat = [[placemark.addressdictionary valueforkey:@"formattedaddresslines"] componentsjoinedbystring:@", "];   nslog(@"addressdictionary %@", placemark.addressdictionary);    nslog(@"placemark %@",placemark.region);   nslog(@"placemark %@",placemark.country);  // give country name   nslog(@"placemark %@",placemark.locality); // extract city name   nslog(@"location %@",placemark.name);   nslog(@"location %@",placemark.ocean);   nslog(@"location %@",placemark.postalcode);   nslog(@"location %@",placemark.sublocality);    nslog(@"location %@",placemark.location);    nslog(@"i @ %@",locatedat);   nslog(@"  "); } ];

but when control goes on line 

 [ceo reversegeocodelocation:locationatual  completionhandler:^(nsarray *placemarks, nserror *error)

this block of code not executed. control goes.

in viewdidload ofyour class or other class add:

- (void)viewdidload {     [super viewdidload]; // add observer         [[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(gotplaceinfo:) name:@"gotplaceinfonotification" object:nil]; }  //define `gotplaceinfo`: -(void)gotplaceinfo:(nsnotification *)notif{  nslog(@"place mark dict  %@", notif.userinfo); }

i have add single line in code:

    clgeocoder *ceo = [[clgeocoder alloc]init];      cllocation *locationatual=[[cllocation alloc] initwithlatitude:[[latlong objectforkey:@"latitude"] doublevalue]                                                           longitude:[[latlong objectforkey:@"longitude"] doublevalue]];      nslog(@"loc %@", locationatual);      [ceo reversegeocodelocation:locationatual  completionhandler:^(nsarray *placemarks, nserror *error)     {       clplacemark *placemark = [placemarks objectatindex:0];  nsdictionary *currentlocationdictionary = @{@"clplacemark":clplacemark};       nslog(@"placemark %@",placemark);       //string hold address       nsstring *locatedat = [[placemark.addressdictionary valueforkey:@"formattedaddresslines"] componentsjoinedbystring:@", "];       nslog(@"addressdictionary %@", placemark.addressdictionary);        nslog(@"placemark %@",placemark.region);       nslog(@"placemark %@",placemark.country);  // give country name       nslog(@"placemark %@",placemark.locality); // extract city name       nslog(@"location %@",placemark.name);       nslog(@"location %@",placemark.ocean);       nslog(@"location %@",placemark.postalcode);       nslog(@"location %@",placemark.sublocality);        nslog(@"location %@",placemark.location);        nslog(@"i @ %@",locatedat);       nslog(@"  "); nsnotification *notification2 = [nsnotification notificationwithname:@"gotplaceinfonotification" object:self userinfo:currentlocationdictionary];     [[nsnotificationcenter defaultcenter] postnotification:notification2];     }     ];

hope give overall learning

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
