Swift中HomeKist发现和管理支持HomeKit的配件（五）

如果我们想打开灯，或者别的控件，首先需要找到改控件，根据该控件找到该控件的服务，根据服务找到该控件的特征，根据特征的描述打开或者关闭该灯，这里只写到特征，控制特征参考下一篇

import UIKit
import HomeKit

class ViewController: UIViewController,HMHomeManagerDelegate,HMAccessoryBrowserDelegate{
    
    @IBOutlet weak var tableView: UITableView?
    var manager: HMHomeManager!
    /*HMAccessory控件，具体到冰箱，洗衣机，空调*/
    var accessories = [HMAccessory]()
    /*HMAccessoryBrowser查找控件的类，*/
    lazy var accessoryBrower:HMAccessoryBrowser = {
        let brower = HMAccessoryBrowser()
        brower.delegate = self
        return brower
    }()
    var home:HMHome!
    var room:HMRoom!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.manager = HMHomeManager()
        self.manager?.delegate = self;
    }
    //homekit初始化完毕
    public func homeManagerDidUpdateHomes(_ manager: HMHomeManager){
        home = self.manager.homes[0]
        room = home.rooms[0]
        //开始查找配件，支持HomeKit
        self.accessoryBrower.startSearchingForNewAccessories()
    }
    
    //发现一个新的配件  HMAccessoryBrowserDelegate
    public func accessoryBrowser(_ browser: HMAccessoryBrowser, didFindNewAccessory accessory: HMAccessory){
        print("-------------(accessory.name)")
        home.addAccessory(accessory) {[weak self] (error) in
            let strongSelf = self!
            if error == nil{
                print("添加控件成功")
                strongSelf.home.assignAccessory(accessory, to: strongSelf.room, completionHandler: { (error) in
                    if error == nil{
                        print("把控件添加房间成功")
                        strongSelf.findServicesForAccessort(accessory: accessory)
                    }else{
                         print("把控件添加房间失败")
                    }
                })
            }else{
               print("添加控件失败")
            }
        }
        
        
    }
    //移除一个新的配件  HMAccessoryBrowserDelegate
    public func accessoryBrowser(_ browser: HMAccessoryBrowser, didRemoveNewAccessory accessory: HMAccessory){
        
    }
    
    func findServicesForAccessort(accessory:HMAccessory){
        print("发现服务")
        for service in accessory.services as [HMService]{
            print("--------service name:(service.name)  type:(service.serviceType)")
            //找到服务，遍历服务的特征
            findCharacteristicsOfService(service: service)
        }
    }
    func findCharacteristicsOfService(service:HMService){
        for characteristic in service.characteristics as [HMCharacteristic]{
            print("???????????????????? characteristic type:(characteristic.characteristicType)")
        }
