Question

所以我有我的委托方法locationManager:didRangeBeacons:inRegion，它给了我NSArray个信标。通常它在阵列中只有1个信标，也就是我目前正在搜索的信标。然而，有时会发生阵列中有多个信标的情况，所有信标都具有相同的信息。它提供相同的主要，次要和UUID，但完全不同的距离读数。

肯定没有6个不同的信标与次要221，但有时它会在NSArray 6次出现。它给出的阵列中的一些距离是完全不准确的，而其他的则不是很糟糕，所以我不确定为什么完全不准确的结果就在那里。 / p>

locationManager:didRangeBeacons:inRegion内的代码如下：

-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
    if(beacons.count>0) {
        for(int i = 0; i < beacons.count; i++) {
            NSLog(@"Beacon #%d: %@", i, [beacons objectAtIndex:i]);
        }
        CLBeacon *beacon = [[CLBeacon alloc] init];
        beacon = [beacons lastObject];

        NSLog(@"%f", beacon.accuracy);
        if(beacon.accuracy != -1.0){
            unknownCounter = 0;
            activityView.hidden = YES;
            if(searching){
                controlView.hidden = NO;
            }
            [self determineHotColdBarColor:beacon.accuracy];
        }
    }else{
        NSLog(@"Couldn't find any beacons");
    }
}

这是我在6次找到相同信标信息时得到的日志：

如果有人知道为什么会发生这样的事情，我会非常感激。谢谢！

locationManager：didRangeBeacons：inRegion beacon数组包含同一个beacon的多个实例
