iphone - GPS 位置在 iPhone 中为我的应用程序打开/关闭

Question

我检查GPS位置是on/off使用此代码

BOOL servicesEnabled = [CLLocationManager locationServicesEnabled];

在 iphone 中打开/关闭 LocationServices 时它可以正常工作，但是我为我的应用程序设置了 LocationServices 它只返回servicesEnabled到YES那个时候[CLLocationManager locationServicesEnabled] 如何签locationServicesEnabled入我的应用程序 例如：我禁用了我的应用程序位置服务，如 instagram，如何解决这个问题LocationServices在 iphone 或 ipad 中 检查特定应用程序的问题？

Answer 1

使用您的CLLocationManagerDelegate's locationManager: didFailWithError:方法并检查kCLErrorDenied错误以查看用户是否拒绝位置服务。

- (void)viewDidLoad
{
    locationManager = [[CLLocationManager alloc] init];

    locationManager.delegate = self;

    locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;

    // Set a movement threshold for new events.

    locationManager.distanceFilter = 500;

    [locationManager startUpdatingLocation];
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)locationManager:(CLLocationManager *)manager

     didUpdateLocations:(NSArray *)locations {

    // If it's a relatively recent event, turn off updates to save power

}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{

    NSLog(@"%@",error);
}

如果您的应用程序禁用了位置服务，那么它会给您错误

Error Domain=kCLErrorDomain Code=1 "The operation couldn’t be completed. (kCLErrorDomain error 1.)"
