Converting two double values to String and then making a string using the new strings

I am trying to convert two values to string and then make a new string containing the ones i made earlier so my service can accept them.

NSString *string1 = [ NSString stringWithFormat:@"%f", locationController.dblLatitude];
NSString *string2 = [ NSString stringWithFormat:@"%f", locationController.dblLongitude];



body = [[NSString stringWithFormat:@"geoX#%@#geoY#%@", string1, string2] dataUsingEncoding:NSUTF8StringEncoding];

This is the code i am using atm. The problem is that both string1 and string2 appear to be ok but the string named body appears to not working.. :< Any help ?

body is not an NSString instance here, but NSData (because you're using `dataUsingEncoding:". If you want to see concatenation of stings in system log you should write something like that:

NSString* bodyString = [NSString stringWithFormat:@"geoX#%@#geoY#%@", string1, string2];
NSData* bodyData = [bodyString dataUsingEncoding:NSUTF8StringEncoding];

and then you can NSLog(@"Body: %@", bodyString); to see it's contents and then use bodyData for making http request.

I believe this is happening because you are just logging the raw data. Try creating a string from the data and then logging it like this:

body = [[NSString stringWithFormat:@"geoX#%@#geoY#%@", string1, string2] dataUsingEncoding:NSUTF8StringEncoding];
NSString *string = [[NSString alloc] initWithData:body encoding:NSUTF8StringEncoding];
NSLog(@"%@",string);

body is not an NSString; it is an NSData because of your call to dataUsingEncoding.
