IOS, how to detect a Bluetooth headset and its events

I am trying to open a “Bluetooth headset” and receive its events. I read the "CoreBluetooth" documentation and implemented a sample code as shown below. It does not run the delegate method " didDiscoverPeripheral".

Is there any solution for this?

the code:

CBCentralManager *myCentralManager;
[myCentralManager scanForPeripheralsWithServices:nil options:nil];


-(void)centralManagerDidUpdateState:(CBCentralManager *)central{

    //following line prints CBCentralManagerStatePoweredOn

    NSLog(@"state:%@", [self getCentralManagerState:central.state]);
}


//following method does not fire

-(void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{

}
