UIRefreshControl无法正常工作

刷新轮停止在95%满,只有从屏幕的最顶部到达底部才能刷新.

lazy var refreshControl: UIRefreshControl = {
    let refreshControl = UIRefreshControl()
    refreshControl.addTarget(self, action:
       #selector(VFeedVC.refresh(_:)),
                            for: .valueChanged)
    return refreshControl
}()

override func viewDidLoad() {
    self.tableView.addSubview(refreshControl)
}

func refresh(_ sender: Any) {
    Metric.sendEvent("RefreshFeed")
    self.refreshControl.beginRefreshing()
    self.getFeeds(self.user.id)
}

func getFeeds(_ userId: Int) {
    VNetwork.getFeeds(userId) { feeds in
        self.feeds = feeds
        self.tableView.isHidden = self.feeds.count == 0
        self.configureCells()
        self.refreshControl.endRefreshing()
        self.tableView.reloadData()
    }
}
