应用关闭，收到推送，点击通知，进不去app

// 获取推送消息
        let remote = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? Dictionary<String,Any>;
        // 如果remote不为空，就代表应用在未打开的时候收到了推送消息
        if remote != nil {
            // 收到推送消息实现的方法，此方法在应用未打开时操作
            self.perform(#selector(AppDelegate.receivePush(_:)), with: remote)
        }else{
            self.loadHomeVC()
        }
