CLRegionState是未知的。當我「米

Question

我測試iBeacon顯示的區域，我使用didDetermineState:方法和CLRegionState是CLRegionStateUnknown當我在該區域內，任何人可以告訴我爲什麼？

我的藍牙是在和探測信標時，我不等他們CLBeaconStateUnknown，發送者和接收者都在範圍（1米），這裏是我實現

-(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region 
{ 

    switch (state) { 
    case CLRegionStateInside: 
     currentBeconRegion = (CLBeaconRegion *)region; 
     [self.locationManager startRangingBeaconsInRegion:currentBeconRegion]; 
     NSLog(@"INSIDE the Region");//not logging 
     break; 
    case CLRegionStateOutside: 
     NSLog(@"OUTSIDE the Region"); 
     break; 
    case CLRegionStateUnknown: 
    default: 
     NSLog(@"Region state UNKNOWN!!!"); //Logging on console 
     statusLabel.text = @"Region state UNKNOWN!!!"; 
    //[self.locationManager stopRangingBeaconsInRegion:beaconRegion];   
    [self.locationManager startRangingBeaconsInRegion:beaconRegion];//Suceessfully ranging the beacon 

     break; 
    } 
}

我已重新啓動我的兩個設備並重新安裝了應用程序，仍然遇到同樣的問題，並且它沒有觸發didEnterRegion:和didExitRegion:。

- (void)viewDidLoad 
{ 

[super viewDidLoad];  
//set peripheralManager delegate 
self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self 
                   queue:nil 
                   options:nil]; 


//Set location managaer delegate 
self.locationManager = [[CLLocationManager alloc] init]; 
self.locationManager.delegate = self; 


uuid = [[NSUUID alloc] initWithUUIDString:@"E01D235B-A5DB-4717-8D2F-28D5B48931F1"]; 

// Setup a new region with that UUID and same identifier as the broadcasting beacon 
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:@"testRegion"]; 
self.beaconRegion.notifyEntryStateOnDisplay = YES; 
self.beaconRegion.notifyOnEntry = YES; 
self.beaconRegion.notifyOnExit = YES; 

}

Answer 2

你說你是「區域內」，但你怎麼知道的iBeacon是否真的被檢測到？藍牙是否開啓並正常工作？用戶在提示時是否允許位置訪問？

我會啓用iBeacon測距和記錄檢測到的任何事情，以驗證您的設備真的看到了iBeacon。我懷疑你會發現你沒有發現任何東西，或者iBeacon.proximity字段由於校準不好而返回CLProximityUnknown。

didDetermineState即使在啓動監控時沒有檢測到信標（或者當您在區域上設置了notifyEntryStateOnDisplay=YES時喚醒屏幕），也會獲得額外的呼叫。這是我認爲你可能得到CLRegionStateUnknown價值的唯一情況。我從未見過這個值返回，所以我很好奇它發生了什麼情況。找到我上面的問題的答案可以解決這個問題。請回報！

Answer 3

我以前有同樣的問題，得到的回答是，我只是忘記了打電話：

[self.locationManager startMonitoringForRegion:beaconRegion]; 

起初我錯誤地認爲，如果你開始使用範圍：

[self.locationManager startRangingBeaconsInRegion:beaconRegion]; 

...並獲取數據的rssi，準確性和UUID在locationManager:didRangeBeacons:inRegion:方法，CLLocationManager應該能夠找出手機在該地區，但顯然不是。因此，要求狀態時，有：

[self.locationManager requestStateForRegion:beaconRegion]; 

我在locationManager:didDetermineState:forRegion:得到CLRegionStateUnknown該區域像你這樣。

Answer 4

這個職位是根據在iOS 8，這可能在未來改變寫着：

我在這裏張貼一個答案的情況下，別人是有同樣的問題，因爲我。在意識到這是因爲我的手機處於飛行模式之前，我總共花了近4個小時。

TL;博士

如果飛行模式，區域通知不來通過
