locationManager：在检测到信标时未调用didEnterRegion

问题描述

在使用信标（iOS设备）进行测试时，我发现监听器信标会发出一些意外行为。即使信标进入某个区域，也不会调用 locationManager：didEnterRegion 方法。但正确调用 locationManager：didRangeBeacons：inRegion：，并在那里显示检测到的信标。有没有人经历过这样的事情。

While testing with beacons (iOS devices) I found the listener beacon giving some unexpected behavior. locationManager:didEnterRegion method is not getting called even if a beacon enters a region. But the locationManager:didRangeBeacons:inRegion: is getting called correctly, and detected beacons are shown there. Has anyone experienced anything like this.

推荐答案

检查你的方法是否以下列方式实现。
在 viewDidLoad 中，最后开始监控

Check if your methods are implemented in the following way.In viewDidLoad, start moniotoring at the end

self.beaconRegion.notifyOnEntry=YES;
self.beaconRegion.notifyOnExit=YES;
self.beaconRegion.notifyEntryStateOnDisplay=YES;
[self.locationManager startMonitoringForRegion:self.beaconRegion];

您所定义区域的请求状态

after monitoring start, request state for your defined region

- (void) locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region
{
    [self.locationManager requestStateForRegion:self.beaconRegion];
}

确定状态后，开始测距信标

after state is determined, start ranging beacons

-(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region
{
    if (state == CLRegionStateInside)
    {
        //Start Ranging
        [manager startRangingBeaconsInRegion:self.beaconRegion];
    }
    else
    {
        //Stop Ranging here
    }
}

并根据您的需要实施以下方法......

and implement the following methods according to your needs...

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region
{
    self.statusLbl.text=@"Entered region";
}

-(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region
{
    self.statusLbl.text=@"Exited region";
}

-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region
{
    if(beacons.count>0)
    {}
}

希望这会解决你的问题问题。
