Question

I am trying to use these two lines to get lat/long info when given an address input.

NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", theAddress];

NSString *locationString = [[[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:urlString]] autorelease];

It is weird that sometimes I get the lat, long info as quick as in 5 seconds and in other cases the app is stuck for about 5 mins and then it logs an error stating “Registration timer expired, but client is still registering!”

It also gives the location info (ie result string wth lat/long info) as null.

I tried it a number of times and couldn’t figure out what makes it work and what doesn’t.

Has anybody encountered the same issue before or any advice on this pls.

Thanks

Answer 1

try below code its working fine with me.

CLLocationCoordinate2D coord=[self gettingLatandLonFromAddress:address];

  -(CLLocationCoordinate2D ) gettingLatandLonFromAddress:(NSString *)address
    {
        CLLocationCoordinate2D currentLoc;
        NSString *urlString=[NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv",[address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
        NSString *locationString=[NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSASCIIStringEncoding error:nil];
        NSArray *listItems = [locationString componentsSeparatedByString:@","];
        double latitude=0.0;
        double longitude=0.0;
        if([listItems count] >=4  && [ [listItems objectAtIndex:0] isEqualToString:@"200"]){
            latitude = [[listItems objectAtIndex:2] doubleValue];
            longitude = [[listItems objectAtIndex:3] doubleValue];
        }
        else{       
            NSLog(@"Error");        
        }

        currentLoc.latitude=latitude;
        currentLoc.longitude=longitude;
        return currentLoc;
    }
