locationManager didExitRegion或locationManager didEnterRegion从未调用过

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);
}

上面是我的代码。我在模拟器中运行，没有位置，然后在调试委派项中设置了客户位置(23.126272,113.395568)，它从不调用didEnterRegion ->location。有人能帮我吗？PS:我的Xcode是7.1.1，控制台日志“开始监控fkit region”

Answer 1

你遗漏了一些步骤。你必须向你的info.plist添加一个条目，声明当你的应用程序在前台时，你想使用定位服务，(使用NSLocationWhenInUseUsageDescription键)，然后你需要检查你是否有权限，如果你没有权限，就请求它。

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

Answer 2

在didStartMonitoringForRegion中添加此行

[self.locationManager requestStateForRegion:yourregion];
