Question

我在iOS 7.x上使用Beacons，通常工作正常，但有时当我拨打startRanging...时，设备启动我错误kCLRangingUnavailable，在检查禁用wifi后，重启蓝牙，然后启动停止airplain模式，这个问题的唯一解决方案是重启手机。

这是我的源代码： @interface RBTMainViewController（） @property（nonatomic，retain）CLLocationManager * locationManager; @end

@implementation RBTMainViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {

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

        NSUUID *estimoteUUID = [[NSUUID alloc] initWithUUIDString:@"00001111-2222-3333-4444-555566667777"];
        CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithProximityUUID:estimoteUUID
                                                                    identifier:@"Proves Range"];

        if ([CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]])
        {
            [_locationManager startMonitoringForRegion:region];
            [_locationManager startRangingBeaconsInRegion:region];
        }
        else
        {
            NSLog(@"This device does not support monitoring beacon regions");
        }


    }
    return self;
}
...
- (void)locationManager:(CLLocationManager *)manager monitoringDidFailForRegion:(CLRegion *)region withError:(NSError *)error{
    NSLog(@"monitoringDidFailForRange: %@ withError: %@", region, error);

}
- (void)locationManager:(CLLocationManager *)manager rangingBeaconsDidFailForRegion:(CLBeaconRegion *)region withError:(NSError *)error{
    NSLog(@"rangingBeaconsDidFailForRange: %@ withError: %@", region, error);
}

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

- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region{
    NSLog(@"RangingBeacons: %@ in (%@)", beacons, region);

}
@end

这是错误发生时iPhone中的输出：

2014-04-14 13:20:18.628 RangingBeaconsTest[9042:60b] monitoringStart: CLBeaconRegion (identifier:'Proves Range', uuid:<__NSConcreteUUID 0x15554170> 00001111-2222-3333-4444-555566667777, major:(null), minor:(null))
2014-04-14 13:20:23.752 RangingBeaconsTest[9042:60b] rangingBeaconsDidFailForRange: CLBeaconRegion (identifier:'Proves Range', uuid:<__NSConcreteUUID 0x15565390> 00001111-2222-3333-4444-555566667777, major:(null), minor:(null)) withError: Error Domain=kCLErrorDomain Code=16 "The operation couldn’t be completed. (kCLErrorDomain error 16.)"

此代码错误，是不可用的范围。有人可以帮我解决这个问题吗？

感谢。
