CoreLocation iOS9存储坐标

Question

我最近问了这个问题，不知道iOS 9中对CL所做的更改。我正在尝试存储用户的当前位置，我已经更改了代码以反映iOS 9中的新委托方法，但didUpdateLocations仍然无法访问。

这是我最初问题的链接：纬度&未检索到的经度

我更新的代码：

视图将出现

- (void)viewWillAppear:(BOOL)animated{
manager = [[CLLocationManager alloc] init];
manager.delegate = self;
if ([manager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
    [manager requestWhenInUseAuthorization];
}
[manager startUpdatingLocation];
}

didUpdateLocations

- (void)locationManager:(CLLocationManager *)manager
 didUpdateLocations:(NSArray<CLLocation *> *)locations{
NSLog(@"Location: %@", locations);
CLLocation *currentLocation = locations.lastObject;
if (currentLocation != nil) {
    float latitude = currentLocation.coordinate.latitude;
    float longitude = currentLocation.coordinate.longitude;

    NSLog(@"dLongitude : %f", longitude);
    NSLog(@"dLatitude : %f", latitude);
}
else{ NSLog(@"ERROR");
     }
}

检查

authorizationStatus and startUpdatingLocation 

和

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status

您还可以进入设置->隐私->位置服务（打开）->选择您的应用程序并在使用时进行选择。
