收到后台BluetoothManager通知 [英] Receive BluetoothManager notifications in background

问题描述

我用我的应用程序的BluetoothManager私人框架，我想知道我怎么能收到BluetoothManager通知，当应用程序在后台（例如：在接收后台连接/蓝牙disconected通知）

I'm using the BluetoothManager private framework in my app and I want to know how can I receive BluetoothManager notifications when the application is in background (ex: Receive the connected/disconected bluetooth notification in background).

先谢谢了。

推荐答案

使用

// global notification explorer
CFNotificationCenterAddObserver(CFNotificationCenterGetLocalCenter(),
    NULL, MyCallBack, NULL, NULL, 
    CFNotificationSuspensionBehaviorDeliverImmediately);

和收到通知：

// global notification callback
void MyCallBack (CFNotificationCenterRef center,void *observer,CFStringRef name,const void object,CFDictionaryRef userInfo)
{
    NSLog(@"CallBack:CFN Name:%@ Data:%@", name, userInfo);
}
