        let app = UIApplication.sharedApplication()
        //设置联网状态
        app.networkActivityIndicatorVisible = app.networkActivityIndicatorVisible ? false : true
        //设置图标消息数字，需要先获得权限
        let userSeting = UIUserNotificationSettings(forTypes: UIUserNotificationType.Badge, categories: nil)
        app.registerUserNotificationSettings(userSeting)
        //再设置数字
        app.applicationIconBadgeNumber = 10
        //打开网址
        app.openURL(NSURL(string: "http://baidu.com")!)
