ios - 监控重叠区域

Question

我在 ios 6 和 7 中使用区域监控。如果区域不重叠，它工作正常。但是，如果某些区域重叠，则应用程序仅为一个区域调用委托(delegate)方法 didEnterRegion。

我的代码:

_locationManager = [[CLLocationManager alloc] init];
_locationManager.delegate = self;

for (XPLocationModel* locationModel in models) {
 if ([self.locationManager respondsToSelector:@selector(startMonitoringForRegion:)]) {
    [self.locationManager startMonitoringForRegion:locationModel.region];
} else if ([self.locationManager respondsToSelector:@selector(startMonitoringForRegion:desiredAccuracy:)]) {
    [self.locationManager startMonitoringForRegion:locationModel.region desiredAccuracy:XPGeofenceMaster_DesiredAccuracy];
}
}

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
   NSLog(@"%s id == %@", __PRETTY_FUNCTION__, region.identifier);
}

- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
   NSLog(@"%s", __PRETTY_FUNCTION__);
}

Answer 1

如果需要，您可以使用 requestStateForRegion: 方法来获取所有状态的更新，就像这样。但是，您最好准备好多次调用 enter 和 exit。

- (void)requestStateForAllLocations
{
    for (CLRegion *region in self.locationManager.monitoredRegions) { 
          [self.locationManager requestStateForRegion:region];
    }
}
