IOS 通知

ios 的通知

swift2.3

NSNotificationCenter.defaultCenter().postNotificationName("HomRefresh", object: data)

NSNotificationCenter.defaultCenter().addObserver(self, selector: "homeRefresh:", name: "HomRefresh", object: nil)//接受消息


func homeRefresh(Notification:NSNotification){
        // 传递的各种类型的数据
        let data = Notification.object as XX


    }

swift 3 里面写法变了 更新下写法

NotificationCenter.default.post(name: NSNotification.Name(rawValue: "namexxx"), object: "数据", userInfo: nil)



NotificationCenter.default.addObserver(self, selector: #selector(self.collcetNotifiaction(_:)), name: NSNotification.Name(rawValue:VideoCollectMessage), object: nil)


    /// 收藏 消息接受
    func collcetNotifiaction(_ sender:Notification)  {
         let cell = self.tableView.cellForRow(at: IndexPath(row: 0, section: 2)) as? VideoNewPageOtherViewMenuCell
        if cell != nil{
            DispatchQueue.main.async {
                cell!.setMenuBtnStatus(3, status: true)
            }
           
        }
    }
