iBeacon測距和接近度是越野車

我正在研究一個類來處理我所有的iBeacon測試。它的目的是開始尋找地區，範圍的信標，確定他們，然後發送通知。代碼如下。iBeacon測距和接近度是越野車

我遇到的問題是應用程序運行速度非常慢，我知道iBeacons有延遲問題，有時只是停止工作（不會識別關閉的燈塔）。我的代碼很混亂，我知道，在我清理它之前嘗試對邏輯進行排序。我想知道我是否在這裏錯過了一個邏輯缺陷（我的意思是，我不知道我介紹過哪些邏輯缺陷！）。

#import "dcBeaconManager.h" 

@implementation dcBeaconManager 

@synthesize currentBeaconState;

信標只發送每隔幾秒鐘，不是？你是否說明了這一點。它不像他們處於連續發送模式... –

我在這幾天工作Estimote iBeacon，我注意到一些延遲和一些問題，以確定出口和在發送通知信標範圍的入口..有時不工作或最近工作。我已將廣告間隔更改爲50毫秒，但沒有任何更改。 – Firegab

您的意思是didEnterRegion和didExitRegion回調被延遲？

如果您的應用程序正在前臺運行，您應該在一秒鐘內輸入區域通知，並在幾秒鐘內退出區域通知。如果您的應用在後臺，最多可能需要15分鐘才能獲得區域內或區域外的通知。

有關此計時的詳細信息，請參閱here。

這些延遲問題不是信標特定的。他們必須處理CoreLocation API在iOS中的實現方式。
