ios - locationManager didExitRegion 或 locationManager didEnterRegion 从未调用

Question

   - (void)viewDidLoad
{

    [super viewDidLoad];

     if([CLLocationManager locationServicesEnabled]){

        self.locationManager = [[CLLocationManager alloc] init];

        self.locationManager.delegate = self;

        CLLocationCoordinate2D companyCenter;

        companyCenter.latitude = 23.126272;

        companyCenter.longitude = 113.395568;


        CLRegion* fkit = [[CLCircularRegion alloc] initWithCenter:companyCenter
                                                           radius:500 identifier:@"fkit"];
        [self.locationManager startMonitoringForRegion:fkit];

    }else{
        NSLog(@"not support");
    }

}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    NSLog(@"Error : %@",error);
}

- (void)locationManager:(CLLocationManager *)manager monitoringDidFailForRegion:(CLRegion *)region withError:(NSError *)error
{
    NSLog(@"Region monitoring failed with error: %@", [error localizedDescription]);
}

- (void)locationManager:(CLLocationManager *)manager didExitRegion:(nonnull CLRegion *)region
{
    NSLog(@"Entered Region - %@", region.identifier);
}

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(nonnull CLRegion *)region
{
    NSLog(@"Entered Enter Region - %@", region.identifier);
}

- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region {
    NSLog(@"Started monitoring %@ region", region.identifier);
}

以上是我的代码。我在没有位置的模拟器中运行，然后在 Debug ->location item 中设置custome location(23.126272,113.395568) ，它从不调用 didEnterRegion delegate 。任何人都可以帮助我吗？
PS:我的Xcode是7.1.1，控制台日志“Started monitoring fkit region”

您缺少几个步骤。您必须在 info.plist 中添加一个条目，声明您想在应用程序处于前台时使用定位服务(使用 NSLocationWhenInUseUsageDescription 键)，然后您需要检查您是否有权限，并询问如果你不这样做。

在 Xcode 文档中搜索字符串“Requesting Permission to Use Location Services”以获取更多信息。
