this code:

locationmanager = [[cllocationmanager alloc] init]; locationmanager.delegate = self; [locationmanager requestwheninuseauthorization]; [locationmanager requestlocation];

if have better way user's location please let me know well.

based on error message, 'delegate must respond locationmanager:didupdatelocations:' have implement locationmanager:didupdatelocations: , locationmanager:didfailwitherror: in delegate in order use requestlocation.
