ios - didUpdateToLocation 从未调用过

Question

我正在使用模拟器和我的设备对此进行测试，但无论我做什么，都不会调用 didUpdateToLocation。我试过更改我在 sim 卡中的位置，关闭然后再次打开我手机上的定位服务以强制手机搜索新位置……什么都没有。在我的 viewDidLoad() 中，我已经启动了 CLLocationManager:

CLLocationManager *manager = [[CLLocationManager alloc] init];

if (![CLLocationManager locationServicesEnabled])    
{
    UIAlertView *servicesDisabledAlert = [[UIAlertView alloc] initWithTitle:@"Location Services Disabled" message:@"You currently have all location services for this device disabled. If you proceed, you will be asked to confirm whether location services should be reenabled." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [servicesDisabledAlert show];

} else {
    manager.desiredAccuracy = kCLLocationAccuracyBest;

    manager.delegate = self;

    [manager startUpdatingLocation];


}

在更新位置方法中我有这个:

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

NSLog(@"NEW LOCATION! Accuracy:[%f]",newLocation.horizontalAccuracy);

}

有没有人知道为什么没有调用它？

您是否在头文件中添加了位置委托(delegate)？
