關於iOS 6.0.1中的Map Kit

Question

我無法在iOS 6.0.1中獲取當前位置，！[[嘗試獲取當前位置時，請查看屏幕快照，地圖視圖未顯示，僅顯示空白地圖屏幕，我當前的位置經度正確

我的代碼如下：

  //Start fetching logged in user current location
    self.m_LocationManager = [[CLLocationManager alloc] init];
    self.m_LocationManager.distanceFilter = kCLDistanceFilterNone;
    self.m_LocationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters;
    self.m_LocationManager.delegate = self;

    [self.m_LocationManager startUpdatingLocation];

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {

    [manager stopUpdatingLocation];

    self.m_LatitudeValue = newLocation.coordinate.latitude;
    self.m_LongitudeValue = newLocation.coordinate.longitude;

    NSLog(@"lat %f long %f",self.m_LatitudeValue,self.m_LongitudeValue);
}


//for showing current location

- (void)addAnnotations { 

    MKCoordinateSpan span;
    span.latitudeDelta=0.08;
    span.longitudeDelta=0.08;


    Social_Check_InAppDelegate *appDelegate = (Social_Check_InAppDelegate *)[[UIApplication sharedApplication] delegate];

    //user current location
        double latitudeValue = appDelegate.m_LatitudeValue;
        double longitudeValue = appDelegate.m_LongitudeValue;



    CLLocationCoordinate2D coardinate1 = {latitudeValue,longitudeValue};
    MKCoordinateRegion region;
    region.center=coardinate1;
    region.span=span;

    CSMapAnnotation *ann = [[CSMapAnnotation alloc]initWithCoordinate:coardinate1];
    ann.title = m_PlacesNameString;
    ann.type = @"green";

    [m_MapView setRegion:region animated:TRUE];
    [m_MapView regionThatFits:region];
    [m_MapView addAnnotation:ann];

    [ann release];
}

上面的代碼顯示治愈

Answer 1

這可能是因為iOS 6不支持

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation 

方法。 請檢查文檔 。 不建議使用上述方法。 在iOS 6及更高版本中，位置管理器在事件可用時將事件報告給其委托的locationManager:didUpdateLocations:方法。
