位置状态栏图标不会消失- MKMapView - iOS 6.1

Question

我有一个包含MKMapView实例的类

@property(nonatomic, weak) IBOutlet MKMapView *ibMapView;

虽然我在项目的其他地方也使用了CLLocationManager的单例实例，但我发现这个地图视图负责在iPhone状态栏上显示"Location“图标。

具体而言，应归咎于以下代码：

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    // If I comment out this line below, the "Location" status icon never shows, as expected 
    self.ibMapView.showsUserLocation = YES;

    // ...other magical stuff happens here, not related to map view
}

我尝试过将showsUserLocation设置为不像这样

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    self.ibMapView.showsUserLocation = NO;

    // I also have tried logging to make sure showUserLocation is set to NO- returns "NO" as expected
    DebugLog(@"Show User Location: %@", self.ibMapView.showsUserLocation ? @"YES" : @"NO");

    // ...other stuff happens here, not related to map view...
}

然而，位置状态图标仍然显示..。即使过了一个小时，它也不会关闭.

如何在showUserLocation实例上将MKMapView设置为YES导致的位置状态图标消失？

事实证明，这是苹果框架中的一个漏洞.

有关解决方案，请参阅此问题和选定的答案：

Location indicator persists on status bar after stopUpdatingLocation is called, but only for old Bundle Identifier

本质上，如果您Reset Location & Privacy (Settings -> General -> Reset -> Reset Location & Privacy)，这就解决了这个问题(只要您还确保完成后showsUserLocation设置为NO )。
