iOS：Homekit - 如何检测设备中是否启用了蓝牙和WiFi服务？

Question

当我们尝试添加附件时，家庭应用程序显示以下警报。

我还在我的应用程序中使用了HomeKit framwork，并希望在用户尝试添加附件时显示警报。

我需要做什么样的更改在应用程序中显示相同的警报？

对于蓝牙在iOS中，你有CBPeripheralManager（在CoreBluetooth框架）。要检查蓝牙连接，声明类为代表的CBPeripheralManager然后创建一个局部变量：

var myBTManager = CBPeripheralManager(delegate: self, queue: nil, options: nil) 

然后，当你的蓝牙启用或禁用您的类必须实现回调得到注意。下面是从我的项目中提取的代码是灯塔经理

//BT Manager 
func peripheralManagerDidUpdateState(peripheral: CBPeripheralManager!) { 
    println(__FUNCTION__) 
    if peripheral.state == CBPeripheralManagerState.PoweredOn { 
     println("Broadcasting...") 
     //start broadcasting 
     myBTManager!.startAdvertising(_broadcastBeaconDict) 
    } else if peripheral.state == CBPeripheralManagerState.PoweredOff { 
     println("Stopped") 
     myBTManager!.stopAdvertising() 
    } else if peripheral.state == CBPeripheralManagerState.Unsupported { 
     println("Unsupported") 
    } else if peripheral.state == CBPeripheralManagerState.Unauthorized { 
     println("This option is not allowed by your application") 
    } 
} 

而对于WIFI，看看这个Github上：https://github.com/ashleymills/Reachability.swift
