ios7 initWithNibName - ios

Question

I'm making an app that determines a user's location and makes the [locationManager startUpdatingLocation] call in the initWithNibName function, but initWithNibName isn't being called right off the back so I added a call for it in the AppDelegate.m:
WhereamiViewController *wvc = [[WhereamiViewController alloc] initWithNibName:#"WhereamiViewController" bundle:nil];
This works, however then there is a problem with calling this function within the initWithNibName function: [locationManager startUpdatingLocation]. It literally returns nothing. But, if I change my code to call initWithNibName in my viewDidLoad line, it works. Why is this? I'm very confused and have been searching for answers but I'm at a standstill. I understand initWithNibName needs to be called, but I don't understand why it won't work if I call it from AppDelegate.m.
- (void)locationManager:(CLLocationManager *)manager
didUpdateLocations:(NSArray *)locations`
- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error
Here is my initWithNibName function:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
// Set a movement threshold for new events.
locationManager.distanceFilter = 500; // meters
[locationManager startUpdatingLocation];
}
return self;
}

Answer 1

you do have a Xib file set up right?
things to try:
if you are not using Nibs then create a method called init:
- (id) init {
self = [super init];
if(self) {
//call code here
}
return self;
}
and then instead of calling nib method in app delegate just call init
or second option would be to call the code straight in viewdidload instead of doing above
