我一直无法弄清楚为什么从未调用startRangingBeaconsInRegion。我肯定知道调用了startMonitoringForRegion，并且我尝试将mRegionsArray输出为字符串并且它有效。但是，并没有调用didEnterRegion。我试着来回走来试图从我的信标中获取信号（即进入该地区），但没有运气。我无法绕过可能出错的地方，在这里经历了很多问题，但没有一个能反映我的问题。
我有一个Beacons表视图，每个单元应该包含每个信标上的信息（主要的，次要的）。除此之外，这些细胞没有被填充，因为测距没有发生。 :(我甚至试图改变它，所以它只检测到一个信标。我知道问题不在我创建的Beacon类中，因为loadTestData（）函数有效...
如果有人可以提供帮助，我们将不胜感激。

在iOS 8下，Apple添加了一些使用位置管理器的新要求（而iBeacons是一个位置管理器功能）
您必须将密钥NSLocationAlwaysUsageDescription和/或NSLocationWhenInUseUsageDescription添加到info.plist文件中，然后在尝试开始监控信标之前，您必须检查授权状态，如果是kCLAuthorizationStatusNotDetermined，您必须拨打新电话，requestAlwaysAuthorization或requestWhenInUseAuthorization
代码可能如下所示：
CLAuthorizationStatus status =[CLLocationManager authorizationStatus];
if (status ==kCLAuthorizationStatusDenied)
{
NSLog(@"Location manager denied");
}
theLocManager = [[CLLocationManager alloc] init];
theLocManager.delegate = self;
if (status == kCLAuthorizationStatusNotDetermined
&& [theLocManager respondsToSelector: @selector(requestAlwaysAuthorization)])
[theLocManager requestAlwaysAuthorization];
（您必须添加检查以确保位置管理响应requestAlwaysAuthorization或requestWhenInUseAuthorization方法，因为它们仅在iOS＆gt; = 8中可用。）
我不喜欢这个操作系统更改的事情是，如果你不进行请求调用，那么开始监视信标的调用将无声地失败。
