MapView位置不起作用（xcode 6中的ios7，SDK ios8）？

Question

I installed XCODE 6 the version form developer.apple (I think is the final one) and Im working my projects there (iOS 7 projects) but obviously brings iOS 8 SDK I really don't know if this affects the project.

I have a mapview and I want to show the user location but it's impossible! Code:

@property (nonatomic, strong) CLLocationManager *manager;

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.manager requestAlwaysAuthorization];
    [self.manager requestWhenInUseAuthorization];
    [self.mapview setDelegate:self];
    self.mapview.showsUserLocation = YES;


    [self.mapview setCenterCoordinate:self.mapview.userLocation.location.coordinate animated:YES];
}

I don't get the "App whants to use your current location...", The mapview shows some place in Africa without pin or anything.

You must init/alloc the CLLocationManager *manager

something like this:

    // Create the core location manager object
        _locationManager = [[CLLocationManager alloc] init];
        self.locationManager.delegate = self;


    // for iOS 8, specific user level permission is required,
    // "when-in-use" authorization grants access to the user's location
    //
    // important: be sure to include NSLocationWhenInUseUsageDescription along with its
    // explanation string in your Info.plist or startUpdatingLocation will not work.
    //
    if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
        [self.locationManager requestWhenInUseAuthorization];
    }
    [self.locationManager startUpdatingLocation];
