ios - Location Manager won't display latitude and longitude -

i have app displays longitude , latitude of users position. application asks current location, , latitude , longitude displays in xcode. in app, nothing happens.

here's code:

- (nsstring *)devicelocation {     nsstring *thelocation =          [nsstring stringwithformat:@"latitude: %f longitude: %f",          locationmanager.location.coordinate.latitude,          locationmanager.location.coordinate.longitude];     return thelocation; } 

in viewdidload:

locationmanager = [[cllocationmanager alloc] init]; locationmanager.distancefilter = kcldistancefilternone; // whenever move locationmanager.desiredaccuracy = kcllocationaccuracyhundredmeters; // 100 m [locationmanager startupdatinglocation];  nslog(@"%@", [self devicelocation]); 

the problem latitude , longitude -labels won't show position.

my guess you're not assigning view controller delegate cllocationmanager.

you can via:

locationmanager.delegate = self; 

right after create locationmanager.

then, can update labels having view controller respond delegate method locationmanager:didupdatelocations:.
